Not in just kidney disease but in every disease “the causes are the preventions”. Knowing the causes can help one to follow, what to prevent. 

In kidney failure, most of the causes are 

• Unhealthy lifestyles and
•  Unhealthy eating habits.

And if we talk about eating habits in peritoneal dialysis, it is strictly restricted in many ways for the patient. 

• When your kidneys are not performing their function, it is important to maintain the urea level. 
• The dietitian will suggest the patient consume high-quality protein. 
• This is recommended so because as we know the kidneys are not able to work properly and filter the waste and extra fluid.
• In this case, high-quality protein will produce less waste which will not pressurize the body and the waste can be removed easily by peritoneal dialysis. 
• Protein is needed in our body but it is also found in the body, produced from the food we eat. 
• Protein is also found in the body which performs some crucial functions like helps fighting against infections, delivering vitamins and nutrients to the body from the consumed food. 
• In dialysis a patient needs to consume more protein to maintain the balance.

There are varieties of food that is rich in high-quality protein. Simultaneously, with clearing the urea, the body loses protein that should stay in the body.

By consuming high-quality protein, you can main the deficiency of protein and balance the loss. A high intake of protein will keep you nourished and healthy. In peritoneal dialysis, the patient will need a good source of protein. 

There is some protein source below that can get on your list during your dialysis to nourish your body.
