Gastrointestinal (GI) bleeding is one of the major indications for hospitalization in the elderly. The most common causes of GI bleeding in elders include peptic ulcer, diverticular disease, angiodysplasia, colitis, and adverse effects of medications. Kalimate (calcium polystyrene sulfonate) is commonly used to treat hyperkalemia, which has rare but severe complications of colonic necrosis and perforation. Cytomegalovirus (CMV) infection of the GI tract is uncommon and can be fatal. Here we present the case of a 73-year-old female with GI bleeding caused by combined cytomegalovirus enteritis and adverse effect of Kalimate.
