Patients that are on dialysis need to take care of their diet in order to control their waste products and fluid levels, and achieve the best dialysis outcome possible. It is necessary for dialysis patients to have the correct amount of calories, proteins, fluids etc in the form of a well-balanced diet each day in order to remain fit, since their kidneys do not function at full capacity. Kidney specialists in Sri Lanka will be able to provide specific dietary guidelines for dialysis patients based on test report parameters, kidney function, pressure and weight.
Typically, a healthy diet for a patient undergoing dialysis entails the following:
|Component||Required amount in diet||Standard values|
|Energy||High for Haemodialysis
Moderate for Peritoneal Dialysis
|30 – 35 kcal/kg BW per day 25–30 kcal/kg BW per day|
|Protein||Adequate for Haemodialysis patients
Adequate for Home Haemodialysis & Peritoneal Dialysis
|1.2 g/kg BW per day
1.2 – 1.3 g/kg BW per day
|Potassium||Low to Moderate||No more than 2 – 3 g per day|
|Sodium||Low||2 – 3 g per day|

Carbohydrates: Calories come in the form of carbohydrates, which should be sufficient in order to achieve and maintain an ideal body weight, and also to prevent the body from using proteins for energy purposes. If the patient has obesity or diabetes then calories will have to be restricted carefully. Carbohydrates include whole grain cereals, non bran cereals, yams, pulses, rice, noodles etc.
Protein: Dialysis patients are required to take adequate levels of protein, such as meat, fish, poultry and egg whites at each meal. As protein rich food contains phosphate, it is vital that patients take phosphate binders with their meals.
Fats: Patients that are on dialysis should consume a diet that is rich in omega 3 fatty acids such as oily fish. Care should be taken to limit saturated fat in order to decrease the risk of heart disease.
Sodium & Fluid: The amount of sodium that a patient requires is determined by the level of kidney function, patient blood pressure and weight. For patients that are on haemodialysis, 2 – 3 g of sodium per day, along with a fluid allowance of 1000 ml per day + urine output is recommended.
Vitamins & Minerals: Folic acid, Vitamin C and Vitamin D are some vitamins that nephrologists in Sri Lanka will prescribe for you. In addition, iron supplements are necessary for anemic patients.
Potassium: It is crucial to control potassium intake through diet. Avoid foods that are high in potassium and take food with low to moderate content such as nuts, beans, fruits and vegetables.
Phosphorus: Foods with high phosphorus levels should be avoided.
