Chronic kidney disease is a silent epidemic of the 21 centuries. Surveys have suggested that as many as 16% of the adult population have CKD1. The most common, non –renal, chronic disorder in patients with ESRD are gastro intestinal disorders2, accompanying ESRD including those receiving renal replacement therapy. Among upper gastrointestinal lesions caused by chronic kidney disease gastritis, esophagitis, gastric ulcer are the most prevalent lesions. Here an attempt is being made to study the upper gastro intestinal changes in chronic kidney disease and evaluate their relationship with the stage of CKD or GFR. Methodology: We conducted a cross sectional study on 50 patients of, who are diagnosed to have chronic kidney disease and being presented to opd and admission in Navodaya Medical College and Research Center, Raichur over a period of one year. All patients with chronic kidney disease who underwent upper gastrointestinal endoscopy were included in the study. Results: 50 patients were included in the study with mean age and males 28 and 22 females. Among 50 patients 42 patients manifested with upper-gastrointestinal lesion among them erosive gastritis 13(26%) is most common upper gastrointestinal lesion followed by gastro esophageal reflux disease with or without duodenitis 8 (16%), duodenal ulcer ,gastric ulcer 4(8%) each, pangastritis 3(6%), GERD with gastritis, erosive duodenitis, erosive esophgitis, pale gastric mucosa 2(4%) each, angiodysplasia and hiatus hernia 1(2%) each. Conclusion: Majority of the patients with chronic kidney disease have upper gastrointestinal involvement on endoscopic evaluation. Erosive gastritis is the most common lesion Esophageal and duodenal involvement are less common than the gastric lesions. Upper gastrointestinal findings are frequently observed in chronic kidney disease patients on dialysis. Early diagnosis and management of these upper gastrointestinal lesions in CKD can reduce mortality and morbidity and prevent fatal complication like massive upper gastrointestinal bleed.
