Unhealthy living is accelerating chronic kidney disease (CKD) in South Africa  to the point where even potential donors are being disqualified, damaging not only their own kidneys but also reducing the chances of saving another’s life.

The South African Medical Journal estimates that 10% of people worldwide suffer from some degree of CKD, meaning that it is likely some 5 million South Africans over 20 years old may be affected by CKD, which significantly impacts their quality of life.

Fadhl Solomon, Cardiovascular (CVS) Product Manager for Pharma Dynamics says roughly 2 000 patients are currently awaiting a kidney transplant in the country, but for some, the chance of them being matched with a suitable donor organ while still healthy enough to undergo a transplant, is slim.

Solomon says diabetes and uncontrolled hypertension (high blood pressure) are leading causes of kidney disease, which over time can impair the function of one or both kidneys.

“Hypertension causes damage to blood vessels and filters in the kidney, making it difficult to remove waste from the body.

“Your kidneys are a pair of fist-sized organs located in your lower back region, on either side of your spine. They are responsible for balancing water and mineral levels in your body by filtering waste products and excess fluids from your blood into urine for excretion. If your kidneys don’t function optimally, it leads to the build-up of fluid and harmful waste products in your body.

“Once diagnosed with end-stage renal disease – a blood-cleansing process, called dialysis or kidney transplantation is necessary.”

Managing your risk of developing kidney disease is paramount.

“Te best way to control blood pressure is by making healthier lifestyle choices. Those who already have hypertension and/or kidney disease, should be prescribed medications that lower blood pressure and can protect the kidneys from further damage.

Preventative measures that can slow disease progression and protect against kidney and cardiovascular disease, include:

• Maintaining a healthy blood pressure by eating healthily, exercising regularly, limiting alcohol intake and quitting smoking.
• Taking combination therapies, such as an angiotensin II receptor blocker and a diuretic (water pill), or an angiotensin‐converting enzyme (ACE) inhibitor with a calcium antagonist have been shown to be effective in patients who do not respond to monotherapy (treatment of disease with one medication).
• Reducing salt intake.
• Maintaining a healthy body weight.

Solomon says there has been some controversy over whether taking anti-hypertensive therapy over the long term can affect your kidneys.

“It’s important to keep in mind that you cannot take certain medication like blood pressure lowering medication or strong anti-inflammatories when you are constantly dehydrated, as this puts additional strain on your kidneys. Adequate hydration is key.”

Some of the symptoms related to kidney disease include high or worsening blood pressure, a decrease in the amount of urine or cloudy or foamy urine, muscle cramps or spasms, dry and itchy skin, unexplained weight-loss, oedema (fluid retention) – especially in the lower legs, a need to urinate more often, especially at night.
