Diet For Chronic Kidney Disease Patients (CKD)


Two kidneys are present on the left and right in the retroperitoneal space or on both sides of your spine of humans. The kidneys are two bean-shaped organs.

They perform several functions, its main job is to filter your blood. Kidneys filter waste products, excess water, and other impurities from your blood. 

Waste products are passed out from the body through urine which are stored in gall bladder.

Kidneys keep the right levels of electrolytes like sodium, potassium, chloride, and bicarbonate, pH and water and also maintain acid-base balance and water balance.

Regular exercise like walking, running, dancing, cycling is good for more than just your waistline. It can lower the risk of chronic kidney disease. It can also reduce your blood pressure and boost your heart health, which are both important to preventing kidney damage.

You have to drink plenty of fluids,you should never become dehydrated. By drinking water required(1,5 to 2 litres/day) daily health of kidney is maintained good. Water also removes toxic substances from kidney and also lowers the sodium, potassium and phosphorus contents.

Chronic Kidney Disease

It is a most common disease of kidneys, it is caused by high blood pressure and diabetes. Hypertension is dangerous for your kidneys because it can lead to increased pressure on the glomeruli, the functional units of your kidney.

So that kidney can’t work properly then you may go for dialysis. Dialysis filters fluid and wastes out of your blood, but it isn’t a long-term solution .You have to transplant a kidney if necessary.

In Diabetes, uncontrolled blood sugar levels leads to reduce the functions of kidney, thus failure of kidney takes place. To maintain health kidney after CKD, we have to restrict or reduce sodium, phosphorus and potassium in your diet.
