Definition
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, including fibrous bands of tissue in the abdomen (adhesions), hernias and 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. 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.
