Your diet will be very important in helping you to feel better and achieve successful treatment. The following dietary nutrients are especially important to regulate in the person receiving dialysis treatment; protein, sodium (salt), potassium, calories and fluids. A dietitian can tell you specifically which foods you should avoid and which foods would benefit you, according to their sodium, potassium and protein content. In general, there are less dietary restrictions after kidney transplant.
It is important that you follow these guidelines that have been suggested specially for you.
(A) Fluid intake
It is extremely important that you strictly adhere to the fluid intake allowance prescribed by your doctor. If you take more fluids than allowed, water will accumulate in your body, leading to serious complications such as a pulmonary edema and hypertension. Generally your fluid intake should be such that the weight gain is restricted to 1.5-2 kg between two haemodialysis sessions.
(B) Sodium (salt) intake
Your doctor will prescribed you a specific amount of salt to be taken per day. Please make sure that you consume the prescribed amount of salt (and not more) every day. Too much of salt intake will result in hypertension, increased thirst etc. Too little salt also will lead to problems such as weakness, and hypotension during dialysis; therefore it is important to take the prescribed amount of salt every day.
Salt substitutes (Lona salt) contain high potassium, hence avoid such preparations.
(C) Potassium intake
|Reduce potassium intake|
Please obtain specific instructions from your dietitian regarding the restriction of these in your diet. The dietitian will help you to choose a low potassium diet which will best suit your particular requirements. Only one fruit (100 gms) can be taken per day (pineapple, apple, papaya or guava).
All vegetables contain potassium. Wash, peel and cut vegetables into small pieces, soak in warm water for 2-3hrs, discard water and add large volume of fresh water, cook and discard water.
Tamarind, spices, condiments and coconut are to be used in very small quantities. They contain very high amount of potassium.
Avoid nuts, jaggery, instant coffee, chocolate, cocoa powder and salt substitutes (Lona salt)
(D) Protein intake
In the pre dialysis phase of Chronic Renal Failure(CRF) all the patients are advised to restrict protein intake. Once the patient is on regular dialysis he/she should take high protein diet (fish, chicken without fat, egg white for non-vegetarians and soya protein for vegetarians)
(E) Calorie intake
It is important that your calorie intake is adequate while you are on maintenance dialysis. Inadequate calorie intake will result in loss of weight, generalized weakness, reduced resistance to infections etc. Therefore, please check with your doctor regarding your daily calorie allowance and adhere to the recommendations given by the doctor.
(F) Dietary intake during the dialysis procedure
You are allowed to take anything you like, during the dialysis, but it must be consumed within the first hour of you dialysis. Even food items rich in potassium may be taken during this time. If you wish to take such items, please make sure that you inform the dialysis technician or nurse who is taking care of your dialysis. When you inform them, they will be able to ensure adequate removal of the excess potassium consumed during the first hour of dialysis.
