Foods You Should Avoid in Kidney Failure

In kidney failure, the kidneys have a hard time excreting waste product and so this waste accumulates in the body which can cause harm to the body. One of the ways that this harm is taken out of the body is through dialysis.

In the simplest of terms, Dialysis is a process where the blood of the person with kidney failure is filtered and the waste product is lost,

This dialysis machine basically does the job of the kidneys, because the kidneys can no longer function


One of the things that the kidneys have a hard time excreting is potassium, and so potassium piles up in your bloodstream


What is potassium and what does it do in the body?


Potassium controls your nerves and muscles and how they function.

Your heart also beats at a regular rate because the potassium levels are okay, any imbalance in this level can lead to an abnormal beating of your heart which can be dangerous for your heart

The kidneys also help to ensure that your potassium is kept a normal level
