Patients: Hi, my father is on dialysis and wants to know if he can have orange, walnuts, almond and grapefruit.
Doctors: For people on dialysis, they usually find their diet is very strict, because though dialysis can replace damaged kidneys to work, it isn’t as effective as healthy kidneys. Potassium is something that dialysis can’t remove from the body completely.
From the above analysis, whether your father can consume orange, walnuts, almond and grapefruit depends on the type of dialysis and the level of his potassium level.
On peritoneal dialysis, the diet isn’t so strict, because peritoneal dialysis is usually done every day. Excess potassium can be removed from the body timely. Therefore, your father can consume these foods with correct amount.
On hemodialysis, the condition will be different. This is because patients commonly do three times of hemodialysis every week. During dialysis sessions, extra potassium will build up in the blood. Therefore, patients on hemodialysis have to pay more attention to foods they are eating.
