Who should not have Sigmoidoscopy?

Sigmoidoscopy may not be suitable for individuals with certain conditions, such as severe rectal bleeding, bowel obstruction, or recent intestinal surgery. Additionally, those with inflammatory bowel disease (IBD) in an active phase or severe heart and lung conditions may also be advised against the procedure. It is essential for patients to discuss their medical history and any potential risks with their healthcare provider before undergoing sigmoidoscopy.
