Haemodialysis is a type of dialysis. In this, the patient is tied up to a special dialysis machine and the blood is purified of all toxins and waste materials. This procedure is prescribed for all patients suffering from end stage kidney disease. These patients have very little or no kidney function and must undergo this blood cleaning procedure to remove their body of excess fluids and wastes. The procedure can be done 3-4 times a week and is normally carried out for 4 hours at a stretch. The machine mimics the function of the kidneys so that you feel well.
The Need For Following A Haemodialysis Diet
A haemodialysis diet is aimed at providing you with a nourishing diet that is high on protein to be able to give the body the essential amino acids. The diet is crucial so that the dialysis treatments are eventually effective. Potassium rich and sodium rich foods are curtailed in a haemodialysis diet.
Too much of potassium in the body is dangerous as it can cause muscle weakness and can make your heart stop beating. The kidney works towards controlling your potassium levels and these levels increase in end stage renal failure. While dialysis helps to control your potassium levels, a correct diet can further enhance the efficacy with which potassium is controlled in the diet.
Phosphorous is a mineral which is difficult to control through the dialysis machine and hence there is a need to curtail its intake. Excess phosphorus can cause heart problems and skin ulcers. Similarly, excess sodium is also not recommended as this can lead to high blood pressure. Here are some of the recommended nutrients in your diet.

Proteins have essential amino acids that are important for your blood. The by-products of protein are urea and creatinine, which are removed by the haemodialysis machine. Lack of adequate protein can lead to excess fluid retention and a reduction in the body’s ability to fight infection. Take protein in the form of fish, eggs, chicken and meat.
Kidney patients fare well if they eat nutritionally dense, complex carbs, which are derived from oats, whole pasta, brown bread and brown rice. These allow the patient to feel satiated and provide him/her with vital calories.
Potassium Foods To Avoid
Potassium tends to build up in the body in between sessions of dialysis. Hence, it is very important to avoid such foods at all costs. The foods to be avoided are beans, coffee and bananas all of which are very high in potassium.
Excess fats raise blood cholesterol levels, leading to heart problems in the patient. Hence, it is crucial to eat a diet that is low on fat and cholesterol. Cut out the fat from the meat, margarine, butter and certain refined oils.
It is very important to also curtail the intake of excess fluids and salt. This only leads to massive fluid retention, which makes it difficult for the dialysis machine to remove. Patients on lifetime dialysis have to be very strict about their diet and have to stick to such diets for life if they are to ever have a clean bill of health.
