Introduction

Loss of appetite is a common concern among patients undergoing dialysis. Many family members become worried when a dialysis patient is not eating, as poor nutrition can lead to weight loss, muscle weakness, reduced immunity, and poorer overall health outcomes. While occasional changes in appetite may occur, persistent refusal to eat should never be ignored.

Several factors may contribute to poor appetite in dialysis patients, including the effects of kidney failure, medication side effects, infections, depression, nausea, altered taste, and dietary restrictions. Identifying the underlying cause is essential so that appropriate treatment can be started early.

At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive dialysis care, nutritional guidance, personalized treatment plans, dialysis optimization, kidney transplant evaluation, and long-term kidney care to help patients maintain the best possible quality of life.
