Managing fluids and diet as a patient on peritoneal dialysis

Managing fluids

Fluid weight is the liquid part of your body. Body weight may change daily depending on what you eat and drink.

It is important to keep fluids in balance. Your healthy kidneys were able to balance the amount of fluid in your body. PD will help remove some extra fluid but you need to pay attention to the amount of fluids taken in and removed from your body. Your weight and how you feel also depend on your fluid balance.



One of the kidneys’ major functions is to maintain the fluid balance in your body. When your kidneys are not working well, they are not able to remove water as effectively.



Protein is a macronutrient important for your everyday health. It is composed of building blocks called amino acids and can be found in every cell of our bodies.



Potassium is one of the main minerals found in your blood. It is also an electrolyte, which means it carries an “electrical charge.”
