Intestinal obstruction is blockage of your small intestine or colon. Your small intestine is the part of your digestive tract following your stomach. After partially digested food moves from your stomach into your small intestine, wave-like contractions move it through to your large intestine or colon. Sometimes the intestines become blocked by strand-like bands of tissue called adhesions. These are internal scars that form between 2 surfaces of the body so they stick together. Abdominal hysterectomy or other abdominal surgeries are a frequent cause of adhesions leading to obstruction of the intestines. When the scar tissue grows over the intestine, it can block the movement of digested food through the digestive tract. The bowel above the obstruction dilates, or gets wider. This causes collection of excess fluid and impairs the flow of blood through the veins and arteries in the walls of the intestine. Without a blood supply, the tissue slowly dies. Ultimately, the wall of dead intestinal tissue can tear open, spilling its contents into the abdominal cavity.
