When you have renal (kidney) failure, it's hard to feel hungry. The build-up of waste products and electrolytes between dialysis treatments can cause you to feel unwell. Restricting the amount of fluids, phosphate and potassium you take in can help. However, it's still important to make sure your body is replenished with the protein, vitamins and minerals it needs each day. Nutrition support from a product like NOVASOURCE^® RENAL can give you the high-quality nutrients your body needs in a small size.
