Risk factors for gastrointestinal<unk>  varies between instrumentation during upper endoscopy, sigmoidoscopy, colonoscopy, stent placement, endoscopic sclerotherapy, nasogastric intubation, esophageal dilatation, and surgery. Other risks include medications especially Aspirin, potassium supplements, disease-modifying antirheumatic drugs (DMARDs), and nonsteroidal anti-inflammatory drug. Peptic ulcer disease is the most common cause of stomach and duodenal<unk> . Colonic diverticulosis is common risk for colonic<unk>  in the developed world. Mesenteric ischemia increases the risk for<unk> . Embolism, mesenteric occlusive disease, and heart failure lead to gastrointestinal ischemia. In neonatal<unk> , prematurity is the commonest risk factor. Antenatal administration of glucocorticoids, nonsteroidal antiinflammatory drugs, indomethacin, and magnesium sulfate had been initially reported to increase the risk of<unk> .
