You’re about to embark on a weight loss journey. You’ve been through your kitchen and thrown all the junk food into the trash. You’ve got a diet plan and you’ve taken those awkward “before” selfies. What is the one thing you might have missed?
Have you made the common mistake of underestimating the caloric content of your favourite drinks?
The majority of beverages consumed by the public are packed with hidden calories. The drinks you might gulp down could be responsible for weight loss plateaus or lack of progress toward your weight loss goals.
The “healthy” smoothie from the organic store? It contains more calories than a double cheeseburger (a large Strawberry Surf Rider from Jamba Juice has 640 calories, a McDonald’s Double Cheeseburger has 440 calories). The coffee on your morning commute? It has the same amount of calories as two glazed donuts (a Venti Starbucks White Chocolate Mocha Frappuccino has 550 calories, while two Dunkin Donuts Glazed Donut have 520 calories). Having a beer with dinner? That’s more calories than a candy bar (a Lagunita’s IPA has 220 calories, while a Hershey bar has 214 calories).
The calories consumed from beverages may be adding hundreds of calories to your daily intake.
Whether it’s juices, flavoured coffees, sodas, beers, or even those popular “healthy” smoothies, they all contain high amounts of calories.
Instead of changing your diet, try rethinking your lifestyle. Don’t count calories, make calories count. The importance of getting the best nutrition out of every calorie will help you reach your goals. Here are a few of the best weight loss drinks to help you get there.
Drinking Your Weight
Most diets place emphasis solely on food—neglected is the significant nutritional value of what you drink. It’s vital to be aware of liquid calories and large quantities of sugar in drinks you’re consuming.
Beverages do not trigger the same satiation responses compared to their solid food counterparts. Studies have shown that meals with solid foods provide better sensations of fullness compared to liquid meal replacements alone.1 When dietary calories are drastically reduced to kick-start weight loss, it becomes crucial that satiation is maximized. Every calorie counts when sticking to a healthy diet.
A typical 16oz bottle of soda has around 200 calories; that’s approximately equal to six ounces of chicken breast. An average juice smoothie from a national chain has around 300 calories; that’s the equivalent to four whole eggs. Most beer has at least 150 calories, equivalent to five pieces of turkey bacon. As you can see, choosing the non-beverage option in each of these scenarios will not only provide more nutritional value, but will also help you feel satiated.
There are several drinks that also tout themselves as diet or zero-calorie options. These drinks have a similar taste but are sugarless. Once sugar is removed, artificial sweeteners are often incorporated into the new drink for taste purposes. These added ingredients mimic the taste of sugar without the added calories.
There is controversy surrounding these sweeteners due to their potential side effects.
- Studies have shown body weight, fat mass, and blood pressure may all be negatively affected by the consumption of sweeteners. Two of the most commonly added artificial sweeteners are aspartame and saccharin.
- Some research has indicated that with sweeteners such as aspartame, sucralose, and saccharin, there’s a potential risk of adverse metabolic effects and type 2 diabetes.
- Monitor your intake of artificial sweeteners as they are often used in zero-calorie drinks.
Try to pick natural, non-processed drink choices that contain minimal artificial sweeteners to be safe.

Losing weight doesn’t have to mean sacrificing all beverage-based enjoyment. There are plenty of lower calorie, healthy options that can satisfy your taste buds and battle the bulge.
Green tea contains valuable antioxidants that supercharge weight loss benefits—extract from green tea is one of the most common ingredients added to fat burning supplements. Tea leaves contain many antioxidants such as catechins, which may help decrease body weight. In research on people drinking green tea along with caffeine, they lost an average of 0.2kg – 3.5kg compared to the control group.
Matcha is a Japanese green tea with higher concentrations of catechins. It contains up to 137x the amount of catechins compared to standard green tea; this higher dose has the potential to further enhance fat oxidation. Caffeine, also in many green teas, may also help support weight loss. In one study, people who were able to maintain weight loss consumed more caffeine.
So, if you’re feeling “hangry,” brew yourself a healthy green tea to help you stay on track.
Another type of tea, black tea, may help reduce body weight. Black tea contains polyphenols, which are micronutrients from plant-based foods. Mounting evidence suggests these antioxidants may help prevent obesity.
The polyphenols in black tea promote weight loss through calorie reduction, increased fat breakdown, and increasing friendly gut bacteria. Who would have thought the humble cup of tea could be a health drink?
Coffee is synonymous with caffeine. Caffeine is the most widely-used nootropic in the world, with millions using coffee as a way to increase energy and potentially increase productivity. At one-point people believed coffee was linked to heart disease and high blood pressure, but in fact recent studies have suggested coffee may actually help prevent chronic diseases such as type 2 diabetes and liver disease.
Coffee may also have positive metabolic effects for both obese individuals and people of healthy weight.
Coffee can boost metabolism. A study found metabolic rate increased significantly three hours after drinking coffee. Furthermore, fat oxidation improved after consumption compared to a control group.
Not only does coffee help with weight loss, it also may help with weight maintenance. Studies have shown caffeine users are able to better maintain weight loss.
Coffee can also reduce energy intake as an appetite suppressant. One study suggests overweight adults who drank coffee were more likely to consume fewer calories. As a result, energy expenditure is reduced.
Water—the Earth is made up of it, your body is made up of it, you need it to survive. Puzzlingly, most people do not get the recommended daily amount. Drinking adequate amounts of water will improve overall health.
Besides the health benefits of proper hydration, water can also help with weight loss. Many people mistake thirst for hunger. There’s a chance you may be overeating if not properly hydrated.
A study performed on overweight adults found those drinking seventeen ounces of water before a meal lost 44% more weight compared to a control group. Having a glass of water before each meal can help control appetite resulting in fewer consumed calories.
Drinking water can also increase resting energy expenditure (REE). REE is the amount of calories consumed at rest over the course of a day. In a study performed on overweight children, REE was increased up to 25% for around 40 minutes after the drink. Consuming the daily recommended amount of water may result in weight loss due to increased expenditure. The results may be true in adults as well.
Some people think drinking regular old water is boring. If you need to spice it up a bit, try adding mint leaves or citrus to hot water or cold water to give it a flavour boost.
Out of the Box Options
Outside of those everyday drinks, there’s a group of less common beverage options for potential weight loss.
Apple Cider Vinegar
Apple cider vinegar probably hides out in your condiments cupboard, but you maybe should bring it out more often. Emerging science suggests that it could be a great extra addition to your weight loss regime. It contains acetic acid, a compound linked to decreased belly fat and reduced accumulation of fat in the liver. In a study performed on rats, apple cider vinegar helped prevent obesity in those with type 2 diabetes. In another animal study, it also reduced body weight in obese mice.
The research on apple cider vinegar performed in humans is limited, but some research suggests it may improve metabolic health in humans. Consuming two tablespoons of ACV per day resulted in decreased body weight, waist circumference, and body fat compared to a control group.
Drinking apple cider vinegar on an empty stomach may help improve digestion; consuming it after meals may improve insulin sensitivity and help lower blood sugar levels.
The versatility of apple cider vinegar makes it a valuable tool for overall wellness.
You may think athletes are the only ones who need to supplement with electrolytes, but everyone needs them to function properly. Drinking enough electrolytes is important to maintain proper fluid balance throughout the body. Sports drinks often have added electrolytes to counteract their loss in sweat as you work out. Unfortunately, many of these products contain high sugar contents, making them calorically dense. Every calorie counts on a diet. Luckily today, there are low-calorie electrolyte drink options available to provide proper electrolyte balance.
Staying properly hydrated is essential for overall health, and is important for weight loss.
While it seems counter intuitive, the body may retain extra water if not properly hydrated. This water weight can add extra pounds on the scale.
No secret here: consuming whole vegetables maximizes nutrient intake. But preparing vegetables takes time—something on which many of us are short.
If you are on the move, vegetable juice is a convenient shortcut to make sure you eat those greens and get plenty of micro-nutrients. Unless you are a rabbit, eating several cups of spinach, broccoli, carrots, and kale in one sitting is hard. Instead, simply grab a blender and combine the ingredients into one beverage. Easy.
People tend to over complicate juicing by adding obscure ingredients together. Make things simple with this easy to follow recipe:
2 cups of spinach
4 stalks of celery
Handful of kale
1 cup of blueberries
Lemon juice to taste
An easy-to-follow. go-to recipe will help meet daily dietary needs, while still being low in calories.
Low Calorie Pre-Workout Drinks
Combining weight loss, dieting and working out may be a difficult balance for many people. They ask: don’t I have to increase my calorie intake to fuel my workouts?
Actually, it’s not essential to eat before working out, and doing some exercise while fasted or in a carb-depleted state can actually increase endurance adaptations.21 When carbohydrate stores are depleted, the body turns to fat as fuel, especially for lower intensity, aerobic exercise. That said, carbs are usually needed to fuel more intense workouts with a high anaerobic component; it can take a while for the body to fat adapt and become efficient at using fat rather than carbs.
Most people are not fat-adapted and tend to workout at a relatively high intensity. In these situations, carbs are generally the body’s workout fuel; having a small amount of carbs pre-workout can protect the quality of your workout, which is important even for individuals on a set diet plan. Just make sure you take into account the amount of energy you need for the workout before you choose your pre-session drink.
Many pre-workout drinks contain a high amount of sugar and carbs to get people pumped and feeling energetic.
For the calorie conscious gym-goer there are several pre-workout drink options containing little to no calories. The bad news is many contain other active ingredients such as beta alanine, tyrosine, and taurine, which supposedly boost your workout, but in reality the evidence for their impact is largely lacking.
What’s more, these extra ingredients often come as part of a proprietary blend, meaning the manufacturer provides little information as to the exact amount of each ingredient included. People should be concerned about putting unknown chemicals into their body in random quantities. It’s nice to know what you are putting in your body.
Instead of consuming pre-workout beverages with a laundry list of ingredients, choose one with fewer additives. Caffeine can be useful during workouts as it provides an extra boost of energy, especially on diet-days where you feel like you lack energy. Sprint, HVMN’s nootropic for energy and focus, has caffeine to help fuel your hardest workouts. And you won’t be spilling coffee and burning yourself as you dash between work and the gym.
For most people 100mg – 200mg of caffeine is sufficient to power through a workout.
Low Calorie Post-Workout Drinks
When sticking to a diet plan, it’s important to properly refuel after intense training sessions. Without proper post-workout fuel, recovery time will be prolonged and strength / endurance adaptations may not be fully realized.
Consuming protein post-workout is one way to maximize your gains. It’s often not possible to rustle up a protein rich meal in the few hours after your gym session; in this case, supplementation is a convenient alternative.
Taking a drink that is rich in protein not only enhances muscle protein synthesis, but also can be satiating as well.
Increasing evidence has shown that whey protein may increase fullness through a satiety-inducing hormone release. Casein and pea proteins in particular have also been shown to have a promising effect on reducing short term food intake. Having a protein shake prior to a meal can help prevent overeating leading to better weight loss results. Just make sure you account for the extra calories from the shake!
There is evidence that having a protein shake prior to sleep may improve protein synthesis, morning metabolism, and overall satiety.
Working out should go hand-in-hand with a proper diet plan to maximize weight loss and improve body composition. Consuming adequate protein will not only maximize your workouts, but may prevent overeating as well.
If you are searching for the extra boost to your performance or simply want to maximize your workout, try HVMN Ketone, the world’s first ketone ester drink. Taken 30 minutes prior to work out, it can elevate levels of the ketone fuel source, beta-hydroxybutyrate (BHB). Having the extra ketone fuel can help improve cognitive and endurance performance. What’s more, it only contains 120 calories (all from ketones).
In tests performed on elite cyclists, those who used HVMN Ketone performed 2% – 3% better, cycling 400m further in a 30-minute time trial. Whether you are striving to be among the most elite athletes on earth or are simply looking for an edge in the gym, HVMN Ketone will be there to push you across the finish line.
For recovery, drinking HVMN Ketone plus a post-workout drink activates pathways that trigger muscle protein regeneration, 2.5x more than a normal carb and protein post-workout drink. This could help athletes to maintain and build lean muscle mass after exercise. If you are on a calorie restricted diet, this may help maintain muscle mass while in a catabolic state.
Not only will HVMN Ketone power you through a workout, it may help curb appetite, lowering levels of hormones associated with hunger.
HVMN Ketone is an exogenous ketone source that can impact on endurance performance and recovery.
Liquid Meal Replacements
Liquid meal replacements have been popular in America for decades. The idea of meal replacements is simple: take out the hassle of cooking and drink your breakfast, lunch, or dinner. The good news—these products tend to be lower in calories than a normal meal and generally have a well-rounded macronutrient profile. They also are often fortified with extra vitamins and minerals.
While these meal replacements may help you stick to daily caloric goals, they tend to lack the satiating properties associated with whole foods. A normal meal replacement shake has approximately 200 calories and 20 grams of protein. Instead of drinking a shake, you could have a small chicken breast with a side of veggies.
In a study performed on liquid versus solid meal replacements, those on liquid meal replacements had greater weight gain over a six-month period. These studies suggest liquid meal replacements should not be substitutes for solid meals, but rather should complement an existing whole food diet.
Liquid Cleanses or Detoxes
Detox diets have become popular over the years due to promises of fast weight loss results.
The reasons these type of drinks work in the short term are two fold. One, if you are on a strict liquid cleanse, you’re consuming far fewer calories daily than recommended. This can be considered the most extreme form of crash dieting.
The other reason cleanses work is their laxative powers. They are designed to make people lose water weight and gut fibre weight as opposed to true fat loss. For someone looking for long term results, we do not recommend these types of cleanses.
DRINKS TO AVOID
Many drinks will contain far more calories than you may realize. These drinks should be avoided as they are high in calories, carbs, and added sugar.
Soda: one 12-ounce soda will contain a minimum of 140 calories
Energy drinks: popular brands of energy drinks contain high amounts of added sugars along with controversial ingredients such as taurine, tyrosine, and beta alanine
Fruit juice: once considered a health food staple, most fruit juices today contain high amounts of added sugars. These processed drinks lack the fibre and nutrition associated with real fruit. They also can trigger more of a blood sugar spike compared to the real thing.
Alcohol: generally, alcohol is not diet-friendly. A full-flavored beer or modest size glass of wine will contain 140 – 200 calories. Spirits are slightly less in caloric value, but become more calorically dense when combined with mixers. If you do choose to drink spirits, mix them with a zero-calorie seltzer water to minimize calories.
Coffee flavourings: adding sweet creamers, syrups and sugar to coffee drinks can rack up calories in a hurry. To avoid this drink, black coffee or only add heavy cream. Or you can add HVMN’s MCT Oil Powder for healthy, filling fats that provide all-day energy.
Drinking these beverages can increase caloric intake in a hurry. In order to avoid this, simply stick to the low or no calorie beverages we have suggested.
Drinking Your Way to Success
Dieting is hard enough already. Don’t make it even more difficult by sabotaging yourself with highly-caloric drinks.
Stick to the basics. And remember to always check nutrition labels to see if your favourite drinks are laden with added sugars (hint: they probably are). Remember not to count calories, make every calorie count.

WEIGHT LOSS DRINKS FOR A SUCCESSFUL DIET
By Adam Felman
Blood pressure is the amount of force that blood exerts on the walls of the arteries as it flows through them. When this pressure reaches high levels, it can lead to serious health problems.
In the United States, approximately one in every three adults has high blood pressure, which equates to about 75 million people, according to the Centres for Disease Control and Prevention (CDC).
Without treatment, high blood pressure, or hypertension, can lead to grave health conditions, including heart failure, vision loss, stroke, and kidney disease.
In this article, we look at the causes of high blood pressure and how to treat it. We also explain the blood pressure measurements that health authorities consider to be healthy and too high.
Age, physical inactivity, and obesity can all increase the risk of high blood pressure.
The heart is a muscle that pumps blood around the body.
It pumps blood with low oxygen levels toward the lungs, which replenish oxygen supplies.
The heart then pumps oxygen-rich blood around the body to supply the muscles and cells. This pumping action creates pressure.
If a person has high blood pressure, it means that the walls of the arteries are constantly under too much force.
It is possible to divide the causes of high blood pressure into two categories:
- Essential high blood pressure: This type of high blood pressure has no established cause.
- Secondary high blood pressure: Another health problem is causing increased blood pressure.
Even though essential high blood pressure has no identifiable cause, strong evidence links specific factors to the risk of developing this condition.
The risk factors for essential and secondary high blood pressure include the following.
Age: The risk of high blood pressure increases as a person becomes older because the blood vessels become less flexible.
Family history: People who have close family members with hypertension have a significantly higher risk of developing it themselves.
Ethnic background: African-American people have a higher risk of developing hypertension than other people. Hypertension also presents more severely in African-American people and is less responsive to certain medications.
Obesity and being overweight: People who are overweight or have obesity are more likely to develop high blood pressure.
Some aspects of sex: In general, high blood pressure is more common among adult men than adult women. However, after the age of 55 years, a woman’s relative risk of hypertension increases.
Physical inactivity: Lack of exercise and having a sedentary lifestyle raise the risk of hypertension.
Smoking: Tobacco intake causes the blood vessels to narrow, resulting in higher blood pressure. Smoking also reduces the blood’s oxygen content, so the heart pumps faster to compensate, causing an increase in blood pressure.
Alcohol intake: Drinking excessive amounts of alcohol can dramatically raise blood pressure and increase the risk of heart failure, stroke, and irregular heartbeat.
Poor diet: Many healthcare professionals say that a diet high in fats and salt leads to a high risk of hypertension. However, most dietitians stress that the problem is the type of fat rather than the amount.
Plant sources of fats, such as avocados, nuts, olive oil, and omega oils, are healthful. Saturated fats and trans fats, which are common in animal-sourced and processed foods, are bad for health.
High cholesterol: More than 50 percent of all people with high blood pressure have high cholesterol. A diet that contains lots of unhealthful fats can cause cholesterol to build up in the arteries.
Mental stress: Stress can have a severe impact on blood pressure, especially when it is chronic. It can occur as a result of both socioeconomic and psychosocial factors.
Excessive stress might also lead to actions that increase the risk of hypertension, such as consuming larger amounts of alcohol.
Diabetes: People with diabetes have a higher risk of developing hypertension. However, prescribed use of insulin and consistent blood sugar control can reduce the long-term risk of people with type 1 diabetes developing hypertension.
People with type 2 diabetes are at risk of hypertension as a result of high blood sugar, as well as other factors, such as certain medications, underlying cardiovascular disease, and being overweight or having obesity.
Pregnancy: Pregnant women have a higher risk of developing hypertension than women of the same age who are not pregnant. Preeclampsia is a placental disorder that can increase blood pressure to dangerous levels.
Sleep apnea: This sleep disorder, which causes people to stop breathing while asleep, might also lead to hypertension.
Signs and symptoms
A person with a headache, nausea, and blurred vision might be experiencing a hypertensive crisis. High blood pressure does not usually cause symptoms.
Most people with high blood pressure will not experience any symptoms. People often call hypertension the “silent killer” for this reason.
However, once blood pressure reaches about 180/120 millimetres of mercury (mm Hg), it becomes a hypertensive crisis, which is a medical emergency. At this stage, symptoms will show, including:
- a headache
- blurred or double vision
- heart palpitations
Anybody who experiences these symptoms should see their doctor immediately.
Children with high blood pressure may have the following signs and symptoms:
- a headache
- blurred vision
- Bell’s palsy, which is an inability to control the facial muscles on one side of the face.
Newborns and very young babies with high blood pressure may experience the following signs and symptoms:
- a failure to thrive
- respiratory distress
People with a diagnosis of high blood pressure should get frequent blood pressure checks. Individuals whose blood pressure is within the normal range should get a reading at least once every 5 years, while anyone with some of the risk factors above should have more frequent checks.
Without treatment or control measures, excessive pressure on the artery walls can lead to damage of the blood vessels, which is a form of cardiovascular disease. It can also damage some vital organs.
The extent of the damage depends on the severity of hypertension and how long it continues without treatment.
Possible complications of high blood pressure include:
- heart attack and heart failure
- blood clots
- kidney disease
- thickened, narrow, or torn blood vessels in the eyes
- metabolic syndrome
- brain function and memory problems
Treatment for high blood pressure depends on several factors, such as severity and the associated risks of developing cardiovascular disease or stroke.
The doctor will recommend different treatments as blood pressure increases:
Slightly elevated: The doctor may suggest some lifestyle changes for people with slightly elevated blood pressure who have a lower risk of developing cardiovascular disease.
Moderately high: If blood pressure is reasonably high, and the doctor believes that the risk of developing cardiovascular disease during the next 10 years is above 20 percent, they will probably prescribe medication and recommend certain lifestyle changes.
Severe: If blood pressure levels reach 180/120 mm Hg or above, this is a hypertensive crisis. An immediate change to the type or dosage of medication may be necessary.
Moderate exercise can help reduce blood pressure.
In 2017, the American Heart Association (AHA) issued guidelines introducing lifestyle adjustments that can help reduce blood pressure.
Discuss any planned lifestyle changes with a healthcare professional before introducing them.
Even walking for 30 minutes on 3–4 days of the week will usually reduce a person’s blood pressure by 4 mm Hg, according to an older study in Hypertension journal.
People should see the benefits quite soon after beginning an exercise program. Blood pressure will usually start to improve within a matter of 2 to 3 weeks, especially in people who are just embarking on a more active lifestyle.
A person should check with their doctor before embarking on any physical activity program and ensure that they tailor exercise to their own needs and state of health.
Exercise is most effective when it is regular. Exercising at weekends and doing nothing from Monday to Friday will be much less effective than exercising every other day, for example.
Studies have revealed that even moderate weight loss of between 5 and 10 pounds can make a significant contribution to lowering elevated blood pressure.
People who are overweight should aim to get closer to their healthy weight range. Blood pressure is likely to fall as a result. Weight loss will also improve the effectiveness of blood pressure medications.
Achieving a healthy body weight involves a combination of exercise, a healthful diet, and at least 7 hours of good quality sleep each night. Keeping a food diary can also improve the effectiveness of a weight loss program.

Some low-quality studies have shown that certain relaxation techniques, including yoga, meditation, and guided breathing, can have a short-term and low-level impact on blood pressure.
The AHA issued a statement noting that there is modest evidence to support the efficacy of some meditation techniques in reducing blood pressure.
A 2014 review found some very low-quality evidence in support of yoga as a way to manage hypertension. However, the authors noted that yoga was no more beneficial for hypertension than regular exercise.
Relaxation techniques may be more effective at an earlier stage of elevated blood pressure.
Although increasing sleep alone cannot treat hypertension, sleep deprivation and poor sleep quality have strong links to high blood pressure.
A 2015 analysis of data from a Korean national health survey found that hypertension was significantly more common among the participants who had less than 5 hours of sleep per night.
However, while improved sleep may support active treatment for high blood pressure, it is not a standalone solution.
Below are some of the most common drugs for treating high blood pressure. Some people might require a combination of several different medications.
1) Angiotensin-converting enzyme inhibitors
Angiotensin-converting enzyme (ACE) inhibitors block the actions of some hormones that regulate blood pressure, such as angiotensin II. Angiotensin II causes the arteries to constrict and increases blood volume, resulting in increased blood pressure.
People with a history of heart disease, women who are pregnant, and individuals with conditions that affect the blood supply to the kidneys should not take ACE inhibitors.
Doctors may order a blood test to determine whether the individual has any pre-existing kidney problems. ACE inhibitors can reduce the blood supply to the kidneys, making them less effective. As a result, regular blood tests are necessary.
ACE inhibitors may cause the following side effects, which usually resolve after a few days:
- a persistent dry cough
If a person finds the side effects too unpleasant or long-lasting to manage, a doctor may prescribe an angiotensin II receptor antagonist instead.
Side effects are less common with these alternative medications, but they may include dizziness, headaches, and increased potassium levels in the blood.
2) Calcium channel blockers
The primary effect of calcium channel blockers (CCBs) is to decrease calcium levels in the blood vessels.
A drop in calcium relaxes the vascular smooth muscle. The muscle contracts less strongly, resulting in the widening of the arteries, which leads to reduced blood pressure.
People with a history of heart disease, liver disease, or circulation issues should not take CCBs.
Individuals using CCBs may experience the following side effects, which usually resolve after a few days:
- redness of the skin, usually on the cheeks or neck
- swollen ankles and feet
- skin rash
- swollen abdomen, in rare cases
3) Thiazide diuretics
Thiazide diuretics act on the kidneys to help the body get rid of sodium and water, resulting in lower blood volume and pressure. They are often a doctor’s first choice of high blood pressure medication.
Thiazide diuretics may cause the following side effects, some of which may persist:
- low blood potassium, which can affect both kidney and heart function
- impaired glucose tolerance
- erectile dysfunction
People taking thiazide diuretics should receive regular blood and urine tests to monitor their blood sugar and potassium levels.
Those over 80 years of age may need to take indapamide (Lozol), a particular type of thiazide diuretic that helps reduce the risk of death from stroke, heart failure, and some other types of cardiovascular disease.
Beta-blockers were once very popular for the treatment of hypertension. Nowadays, people are more likely to use them when other treatments have not been successful.
Beta-blockers slow the heart rate and reduce the force of the heartbeat, causing a drop in blood pressure.
These drugs may cause the following side effects:
- cold hands and feet
- slow heartbeat
The side effects below are also possible, but they are less common:
- disturbed sleep
- erectile dysfunction
Beta-blockers are often the standard medication for a hypertensive crisis.
5) Renin inhibitors
Aliskiren (Tekturna, Rasilez) reduces the production of renin, which is an enzyme that the kidneys produce. Renin plays a key role in the production of angiotensin I, a protein that the body converts into the hormone angiotensin II. This hormone narrows blood vessels and raises blood pressure.
Aliskiren blocks the production of angiotensin I to reduce levels of both angiotensin I and II.
By doing this, it causes the blood vessels to widen, resulting in a drop in blood pressure. As it is a relatively new medication, healthcare professionals are still determining its optimal use and dosage.
Aliskiren may have the following side effects:
- flu-like symptoms
- a cough
It is essential to read the packaging of any medication to check for interactions with other drugs.
A healthful diet can help reduce blood pressure.
Managing the diet can be an effective way of both preventing and treating high blood pressure.
A healthful, balanced diet includes plenty of fruits and vegetables, vegetable and omega oils, and good-quality, unrefined carbohydrates. People who include animal products in their diet should trim all the fat off and avoid processed meats.
Lowering salt intake
The World Health Organization (WHO) strongly recommend that their member states take active steps to reduce salt consumption across the whole population.
Reducing salt intake by 3 grams per day could have profound effects on cardiovascular health, reducing systolic blood pressure by 5.6 mm Hg in people with hypertension.
The AHA recommend limiting salt intake to no more than 2,300 milligrams (mg) every day, with a view to eventually reducing this amount to 1,500 mg. People in the U.S. currently consume an average of more than 3,400 mg of sodium daily.
Those who often lose large quantities of sodium in the sweat, such as athletes, do not need to reduce their salt intake to the same extent.
The DASH diet
Number of weekly servings for those eating 1,600–3,100 calories a day
Number of weekly servings for those on a 2,000-calorie diet
Grains and grain products
Mostly low-fat or non-fat dairy foods
Lean meat, fish, or poultry
Nuts, seeds, and legumes
Fats and candy
The National Institutes of Health (NIH) designed a way of eating to control blood pressure called the DASH diet. The AHA also recommend this diet for people with high blood pressure.
The DASH diet focuses on an eating plan that emphasizes fruits, vegetables, nuts, seeds, beans, and low-fat dairy products.
People who are following the diet should ensure that they eat three whole-grain foods each day.
The plan essentially uses a “pyramid” of healthful foods, with grains, fruits, and vegetables making up the foundation of the diet and fats, sweets, and meat forming the top of the pyramid, which represents much lower consumption.
Some studies indicate that consuming alcohol helps lower blood pressure, while others report the opposite.
In minimal amounts, alcohol may lower blood pressure. However, drinking too much, even in moderate amounts, might increase blood pressure levels.
People who regularly drink more than moderate amounts of alcohol will almost always experience elevated blood pressure levels.
Many studies report on the relationship between caffeine and blood pressure. They have conflicting conclusions but agree that moderating caffeine intake is advisable for people with high blood pressure.
Anyone whose blood pressure is 140/90 mm Hg or more for a sustained period has stage 2 high blood pressure.
Doctors will define a blood pressure reading under one of the following five categories:
- Normal: Less than 120/80 mm Hg.
- Elevated: 120–129/80 mm Hg. At this stage, a doctor will advise the individual to make lifestyle changes to return their blood pressure to the normal range.
- Stage 1: 130–139/80–89 mm Hg.
- Stage 2: Over 140/90 mm Hg.
- Hypertensive crisis: 180/120 mm Hg or above.
A person in hypertensive crisis may need a prompt change in medication if they give no other indications of problems. Immediate hospitalization may be necessary if organ damage has occurred.
There are two parts to a blood pressure measurement:
- Systolic pressure: This is the blood pressure when the heart contracts.
- Diastolic pressure: This is the blood pressure between heartbeats.
If blood pressure is 120/80 mm Hg, it means that the systolic pressure is 120 mm Hg and the diastolic pressure is 80 mm Hg.
A sphygmomanometer measures blood pressure.
Most people will have seen this device, which consists of an inflatable cuff that wraps around the upper arm. When the cuff inflates, it restricts blood flow.
A mercury or mechanical manometer measures blood pressure.
A doctor will often use a manual sphygmomanometer together with a stethoscope. With a digital sphygmomanometer, electrical sensors take all of the measurements.
Advances in new wearable technology mean that people can now keep track of their blood pressure at home. Read our review of the best home blood pressure monitors currently available for home use.
One blood pressure reading is insufficient to diagnose hypertension. Blood pressure can fluctuate during the day, and a visit to the doctor may cause the reading to spike due to anxiety or stress.
A recent meal may also temporarily affect blood pressure readings.
As the definition of hypertension is “repeatedly elevated blood pressure,” a healthcare professional will need to take several readings over a fixed period. They may take three separate measurements, each a week apart. Often, the monitoring goes on for longer than this before the doctor confirms a diagnosis.
People with extremely high blood pressure or signs of end-organ damage should receive an immediate diagnosis to enable prompt treatment.
End-organ damage is damage to major organs that the circulatory system feeds directly, such as the heart, kidneys, brain, and eyes.
Kidney disorder: If an individual with high blood pressure also has a urinary tract infection (UTI), urinates frequently, or reports pain along the side of the abdomen, they could have a kidney disorder.
If the doctor hears the sound of a rush of blood when they place a stethoscope on the side of the abdomen, this could be a sign of stenosis. Stenosis is the narrowing of an artery supplying the kidney.
Additional tests for high blood pressure
The doctor may order the following tests before confirming a hypertension diagnosis.
Urine and blood tests: The underlying cause of high blood pressure might be an infection, a kidney malfunction, or high levels of cholesterol, potassium, or blood sugar. Protein or blood in the urine may indicate kidney damage, while high glucose in the blood might be due to diabetes.
Exercise stress test: An exercise stress test is a more common test for people with borderline hypertension. It usually involves pedaling on a stationary bicycle or walking on a treadmill.
The test assesses how the cardiovascular system responds to a spike in physical activity.
It is vital to declare a hypertension diagnosis before the start of the test. The test monitors the electrical activity of the heart, as well as the blood pressure during exercise.
An exercise stress test sometimes reveals problems that might not be apparent when the body is at rest. The doctor might take imaging scans of the blood supply to and from the heart.
Electrocardiogram (ECG): An ECG tests electrical activity in the heart. This test is more common in people with a high risk of heart problems, such as hypertension and elevated cholesterol levels.
Healthcare professionals call the initial ECG a baseline. They might compare subsequent ECGs with the baseline to reveal any changes, which might point to coronary artery disease or thickening of the heart wall.
Holter monitoring: For 24 hours, the individual carries an ECG portable device that connects to their chest through electrodes.
This device can provide an overview of blood pressure throughout the day and show how it changes as the level of activity varies.
Echocardiogram: This device uses ultrasound waves, which show the heart in motion. The doctor will be able to detect problems, such as thickening of the heart wall, defective heart valves, blood clots, and excessive fluid around the heart.
High blood pressure is a health problem that often causes no symptoms but can lead to severe health complications. Some underlying conditions can cause high blood pressure, but the exact cause of other cases is unknown.
Age, race, sex, lifestyle, family history, pregnancy, and stress can all contribute to high blood pressure, which can increase the risk of stroke and heart disease.
A healthful lifestyle and a balanced diet can help keep high blood pressure at bay.
A doctor will try to manage hypertension by recommending lifestyle changes, such as following the DASH diet, and prescribing medications.
