Enteroscopy might not be recommended for people with particular medical conditions or risk factors that could lead to complications. Due to the sedation and the procedure itself, individuals with severe heart or lung disease, uncontrolled bleeding disorders, or recent heart attacks may be at higher risk. Additionally, those with anatomical abnormalities or strictures in the digestive tract might be advised against it. It's important to consult your healthcare provider about any health conditions or concerns to decide if an enteroscopy is right for you.
