Enteroscopy might not be suitable for individuals with certain health issues that heighten the risk of complications during the procedure. This includes those with severe cardiovascular or respiratory conditions, uncontrolled bleeding disorders, or those who have recently suffered a heart attack. People with structural abnormalities or narrowing in their digestive tract may also be discouraged from having an enteroscopy. It is crucial to consult with your healthcare provider about any health conditions you have to determine if enteroscopy is safe for you.
