According to MedlinePlus, people are capable of living without their small intestines, although difficulties with digestion can occur after the removal. A surgery known as a small bowel or small intestine resection involves the removal of either a portion of or the entirety of the small intestine.
MedlinePlus states that surgeons perform small intestine resection surgeries when disease or blockage in the area necessitates it. Because the small intestine is where most of the digestion process occurs, people without their small intestines might experience difficulty absorbing sufficient nutrients from their food intake. Problems with loose stools can also occur. Most people who undergo a small intestine resection are able to resume normal activities.
