Bowel obstruction occurs when there is a partial or complete block in the normal passage of digested material through the small and large intestine. The symptoms depend of the location of the blockage within the intestinal tract. In addition, the degree of obstruction is of vital importance and governs the type of symptoms which are produced. Symptoms tend to develop more quickly with the obstruction of the small intestine than with the obstruction of the large intestine. Complete obstruction leads to constipation and abdominal swelling. Repeated episodes of severe abdominal pain occur, associated with nausea and vomiting.
Causes of Bowel Obstruction
The most common cause of bowel obstruction is adhesions or scars within the abdomen caused by previous abdominal surgery. A portion of the intestine may become trapped in a hernia, a defect in the muscular layer of the abdomen. This may lead to bowel obstruction and damage or death to that portion of the intestine trapped in the hernia. Intussusception, where a portion of the intestine collapses into an adjacent portion of the intestine can produce bowel obstruction. Colon cancer can lead to obstruction of the lumen or opening of the large intestine as the tumor increases in size. Diverticulitis, inflammation of infection of small pouches which develop in the wall of the large intestine can produce bowel obstruction. Foreign bodies or hard stool can occasionally obstruct the intestinal tract. Adynamic ileus occurs after abdominal surgery. Here the normal contractions of the intestine stop in response to surgery. They usually recover on their own within several days.
Signs and Symptoms of Bowel Obstruction
The most common symptom of bowel obstruction is intermittent episodes of abdominal pain. These pains come in waves, and are often associated with nausea and vomiting. There is progressive swelling of the abdomen and progressive constipation. Weakness, fever, and bad breath occurs. As the problem worsens, the intestinal wall becomes further dilated. It may develop perforations or interfere with its own blood supply. These problems can result in peritonitis or death of a portion of the intestine.
