Gastrointestinal disease in end-stage renal disease

Abstract

When kidney function declines to a point where it can no longer maintain life and requires renal replacement therapy (i.e. renal transplant or dialysis), it is called end-stage renal disease (ESRD). Patients with ESRD often experience a range of gastrointestinal (GI) symptoms, with prevalence rates reported as high as 77%-79%. These symptoms and pathologies arise from various factors, including electrolyte imbalance, fluid imbalance, toxin buildup, uremia, medications, dietary and lifestyle restrictions, and the effects of dialysis. GI diseases in patients with renal failure can be further categorized into upper GI, small bowel, and lower GI issues. Common conditions include gastroesophageal reflux disease, nausea and vomiting, dysmotility within the esophagus and stomach, upper GI bleeding, peptic ulcer bleeding, angioectasia, irritable bowel syndrome, mesenteric ischemia, angiodysplasia, diverticular disease, constipation, pancreatitis, and diseases associated with peritoneal dialysis peritonitis and peritoneal stenosis. This review assesses the existing literature on the different GI diseases among individuals with ESRD, shedding light on their pathophysiology and prevalence.

Core Tip: Due to electrolyte imbalance, fluid imbalance, toxin buildup, uremia, medications, dietary and lifestyle restrictions, and the effects of dialysis, patients with renal failure experience gastrointestinal complications with a prevalence of 77%-79%. Common conditions include gastroesophageal reflux disease, nausea and vomiting, dysmotility within the esophagus and stomach, upper gastrointestinal bleeding, peptic ulcer bleeding, angioectasia, irritable bowel syndrome, mesenteric ischemia, angiodysplasia, diverticular disease, constipation, pancreatitis, and diseases associated with peritoneal dialysis peritonitis and peritoneal stenosis.
