Ischaemic colitis is the most common form of intestinal ischaemia and is more common in the elderly and in the people having risk factors for colonic ischaemia. Colonoscopy procedure itself is a rare cause of ischaemic colitis. Fewer than 20 cases of ischaemic colitis caused by colonoscopy procedure have been reported in the english literature till date. This patient presented to us within hours of routine colonoscopy with rectal bleeding and lower abdominal pain. On repeat colonoscopy, the patient had mucosal oedema and ulcerations in the descending colon and sigmoid colon. Computed tomography of abdomen and biopsy of the involved segment confirmed ischaemic colitis. The patient recovered with conservative management.
