Enteroscopy may not be recommended for individuals with specific medical conditions or factors that elevate the risk of complications. Those with severe heart or lung disease, uncontrolled bleeding disorders, or recent heart attacks may not be suitable candidates due to the risks associated with sedation and the procedure itself. Additionally, individuals with anatomical abnormalities or strictures in their digestive tract may be advised against undergoing enteroscopy. It's crucial to discuss any current health conditions or concerns with your healthcare provider to determine if enteroscopy is suitable for you.
