Understanding an Intestinal Obstruction
When your intestine works normally, digested food moves from your stomach to your rectum. Along the way, your body toàn thân breaks food down into usable parts and turns the rest to feces ( stool ). You eventually eliminate it through a bowel movement .
An intestinal obstruction may partially or completely block this natural process. A complete blockage is an emergency and needs medical attention right away .
Among the many possible reasons for an intestinal obstruction are:

Abdominal adhesions. These are growths of tissue in bands that may force your intestines out of place.
-
Hernia. A hernia is a split in the muscle wall of your abdomen. Hernias can cause bulges and pockets. These may block your intestine.
-
Volvulus. A volvulus happens when part of your intestine twists around itself. This creates a blockage.
-
Intussusception. This condition means that a segment of your intestine slides into another segment. This narrows but may not block your intestine.
-
Scarring. When your body heals small cuts (wounds), scar tissue forms. This can happen inside your intestine as well. These scars can build up and create partial or total intestinal blockages. Scarring can result from tears in your intestinal wall, belly (abdominal) or pelvic surgery, or infections.
-
Inflammatory bowel disease. Crohn’s disease and ulcerative colitis are 2 examples.
-
Diverticulitis. Tiny pouches (diverticulae) can grow off the large intestine lining. These may become inflamed.
-
Tumors. Growths may be cancer or harmless (benign). Either way, they can block your intestine completely or partially.
-
Foreign objects. Nonfood objects that you swallow on purpose or accidentally may cause partial or complete intestinal obstruction.
-
Meckel diverticulum. About 2 in 100 people are born with this additional small pouch inside the intestine.
