If you look after your kidneys, you also look after your body

While our kidneys may be small in size, they play a crucial role in our health and well-being. In commemoration of National Kidney Awareness Week (2 to 6 September), the Western Cape Department of Health and Wellness reminds residents of the key steps they can take to keep their kidneys in good working order and reduce their risk of developing chronic kidney disease.

Kidneys help regulate blood pressure, produce red blood cells, and maintain the health of our bones, to name a few crucial roles. Unfortunately, kidney disease often goes undetected (nine out of 10 people with kidney disease do not know they have it). This is because many people whose kidneys do not work properly, do not develop symptoms until their kidneys are close to failing.

Dr. Zunaid Barday, a nephrologist at Groote Schuur Hospital, says kidney disease can affect people of all ages and backgrounds. “Early kidney disease often has no signs or symptoms. An individual can lose up to 90 percent of their kidney function before experiencing any signs. To detect if you have kidney disease, you can have a urine or blood test taken to check if there is any protein in your urine, and to measure the level of creatine in your blood.

Prof. Yazied Chothia, a nephrologist at Tygerberg Hospital, says managing kidney disease is crucial to slowing its progression and maintaining overall health. “Drinking water is the best way to keep your kidneys hydrated. Next, think about what you eat. Adopt a kidney-friendly diet by reducing salt intake. Aim for less than one teaspoon of salt each day. Smoking is bad for your kidneys, as it closes up the blood vessels in the kidneys and also increases blood pressure. On the other hand, exercise is good for the kidneys. You can also help your kidneys by keeping to a healthy weight.

As it is not easy to spot yourself when your kidneys might have a problem, it is important to be aware of whether you need a regular kidney check. Your doctor or nurse will then be able to tell you whether you need any regular check-ups or any medication.
