Best Foods to Take for Dialysis Patients
Fluids: Due to the impaired function of kidneys, they are not able to get rid of the excess water from the body. This leads to water retention which can increase the blood pressure. Therefore, the intake of fluids should be limited. One should not have fruit juices or water containing fruits like melons, grapes, etc. Water and other beverages should also be consumed in limited amounts.
Sodium: Sodium containing foods make one thirsty, which will consequently increase fluid intake. Therefore, it is wise to cut down on sodium containing foods. Salted foods, spices, preserved foods should be avoided. Rather, one should have fresh foods and those marked with 'low sodium'.
Proteins: Once the person is on dialysis, his protein requirement increases. Specially people on the peritoneal dialysis have a higher requirement of proteins as much proteins are lost when the peritoneal fluid is discarded. Meat and meat substitutes, egg, fish, milk and dairy produce are some protein containing products that can be eaten. However, one should note that higher intake of proteins can exert pressure on the already weak kidneys. Therefore, it is wise to consult a doctor about the protein intake.
Potassium: People on hemodialysis (HD) need to lower their intake of potassium as potassium can build up in the body, in between the sessions of dialysis, which can lead to hyperkalemia. On the other hand, people on peritoneal dialysis (PD) should have higher potassium intake as their potassium levels fall due to daily dialysis. Tomatoes, bananas, oranges, contain high potassium.
Phosphorus: You also need to limit the intake of phosphorus containing foods, irrespective of whichever dialysis you are undergoing. This is because excess phosphorus in the body causes hollowing of bones. Cheese, peas, nuts, peanut butter, contain high amounts of phosphorus and hence, should be avoided. The phosphorus obtained from meat and vegetables is sufficient for the body.
