Chronic kidney disease (CKD) is known as a ‘silent killer’ as most people live with the disease for years before they have any symptoms. By the time the disease is detected, for many people it’s already too late. Hypertension and diabetes are the most common causes of CKD. Other much fewer common conditions that can cause CKD include inflammation, infections, genetics, or longstanding blockage to the urinary system (such as enlarged prostate or kidney stones

 In an advanced stage, CKD can only be treated with regular dialysis or through a kidney transplant making it very expensive to manage. Early detection and prevention are essential. However, it can usually be prevented by controlling key risk factors but, most countries have no strategy for chronic kidney disease.

Left untreated, CKD progresses from Stage 1 through to Stage 5. Stage 5 is also known as End-Stage Renal Disease (ESRD), which means regular dialysis treatment, or a kidney transplant is needed to survive.

Fast Facts about Chronic Kidney Disease 

  • Early chronic kidney disease has no signs or symptoms – many people living with CKD don’t even know it until the disease is in an advanced stage.
  • About 10% of the adult population is living with some degree of CKD, and every year millions die prematurely from CKD and related complications.
  • CKD is a major risk factor for cardiovascular diseases, which are the primary cause of death for all people living with CKD.
  • If CKD is detected early and managed appropriately, the deterioration in kidney function can be slowed or even stopped, and the risk of associated cardiovascular complications can be reduced.
  • CKD is largely preventable and can be detected early with simple blood and urine tests.

Symptoms and complications of CKD may include:

  • High blood pressure
  • Anaemia (low blood count)
  • Weak bones
  • Poor nutritional health
  • Nerve damage
  • Swollen ankles
  • Fatigue

Another consequence of CKD is that it increases the risk of early death from associated cardiovascular disease (i.e., heart attacks and strokes). People living with CKD therefore have an increased risk of dying prematurely from cardiovascular disease, regardless of whether they ever develop kidney failure.

How can we prevent chronic kidney disease?

There are several ways to reduce the risk of developing kidney disease.

  • Be active
  • Eat a healthy diet
  • Reduce your salt intake
  • Don’t smoke
  • Check and control your blood sugar and blood pressure as part of your regular check-ups
  • Get your kidney function checked if you have one or more of the ‘high risk’ factors: diabetes, hypertension, obesity, a family history of CKD.

 Blood and urine tests can easily detect CKD and simple, low-cost treatments can slow the progression of the disease, reduce the risk of associated heart attacks and strokes, and improve quality of life.

The early detection of failing kidney function can be lifesaving because it allows CKD to be treated through medications, diet, and lifestyle changes rather than dialysis or a kidney transplant, which are economically inaccessible for most people around the world. These treatments are known as renal replacement therapies (RRT) because they attempt to “replace” the normal functioning of the kidneys.

When you have kidney failure, wastes and fluids accumulate in your body and you need regular dialysis treatments for life to remove these wastes and excess fluid from your blood. For patients who can access it, a kidney transplant combined with medications and a healthy diet can restore normal kidney function.

Note this! About 1.3 million people die from kidney disease each year, with an additional 1.4 million deaths from cardiovascular disease that are attributed to impaired kidney function.

CKD is increasing in prevalence – and at an alarming rate. CKD deaths increased by 41.5% from 1990 to 2020, rising from the 17th leading cause of death to the 10th. Now, it is expected that CKD will climb to the fifth leading cause of death globally by the year 2040.

This is primarily due to changes in the way we eat, drink and move – as the junk food industry reaches virtually all corners of the world with its health-harming products and aggressive marketing techniques, diabetes and hypertension – the key risk factors for CKD – are skyrocketing. Most of this increase is occurring in low- and middle-income countries (LMICs) and among more marginalised communities in all countries.

CKD can occur at any age but becomes more common with increasing age and is more common in women. Although about half of people aged 75 or more have some degree of impaired kidney function, many of these people do not actually have diseases of their kidneys; they have normal ageing of their kidneys.

The cost of treating CKD represents an enormous burden on healthcare systems worldwide. In developed countries, kidney failure is a major cost driver for patients, their families and governments. For instance:

  • According to a recent report published by NHS Kidney Care, in England, CKD costs more than breast, lung, colon and skin cancer combined.
  • In the US, treatment of CKD is likely to exceed USD 48 billion per year, and the Stage 5 program consumes 6.7% of the total Medicare budget to care for less than 1% of the covered population.

In middle-income countries such as Nigeria, access to life-saving therapies has progressively increased, yet renal replacement therapy (dialysis or transplant) remains unaffordable for the vast majority of patients. Developing countries cannot afford dialysis or transplants at all—resulting in the deaths of over 1 million people annually from untreated kidney failure.

It is clear that we are not all equal with regard to kidney disease and access to treatment.
