Enteroscopy might not be advised for those with certain medical conditions or risk factors that increase the likelihood of complications. Those with severe heart or lung disease, uncontrolled bleeding disorders, or recent heart attacks may have heightened risks due to sedation and the procedure. Additionally, people with anatomical abnormalities or strictures in the digestive tract might be advised against it. Please discuss any existing health conditions or concerns with your healthcare provider to see if enteroscopy suits you.
