By Mayo Clinic staffIntestinal obstruction is a blockage of your small intestine or colon that prevents food and fluid from passing through. Intestinal obstruction can be caused by many conditions, but it's most often the result of fibrous bands of tissue in the intestine (adhesions), hernias or tumors.
Intestinal obstruction can result in an array of uncomfortable signs and symptoms, including abdominal pain and swelling, nausea, and vomiting. If left untreated, intestinal obstruction can cause the blocked parts of your intestine to die (become necrotic). This tissue death can lead to perforation of the intestine, severe infection and shock. However, with prompt medical care, intestinal obstruction can often be successfully treated.
