What causes bowel obstruction?
A bowel obstruction occurs when there is a blockage that prevents the passage of intestinal contents that should be excreted. Blockages can be mechanical or caused by ileus.
Mechanical causes of bowel obstruction
Mechanical obstructions are physical blockages due to various causes including:
- Adhesions (scar tissue from previous surgery or infections)
- Diverticulitis (inflammation of small pouches of the bowel)
- Foreign bodies
- Impacted feces
- Intussusception (sliding of part of the intestine into an adjacent part)
- Volvulus (twisting of the intestines)
Causes of ileus
Ileus, a malfunctioning of the movement of the bowel, is another type of obstruction. Causes of ileus include:
- Certain drugs and medications, such as opioids and sedatives, which slow down peristalsis, the contractions that propel food through the digestive tract
- Electrolyte imbalances
- Gastroenteritis (inflammation or infection of the stomach and intestines)
- Obstruction of the mesenteric artery, which supplies blood to the abdomen
What are the risk factors for bowel obstruction?
A number of factors increase the risk of developing bowel obstruction. Diseases and tumors of the gastrointestinal tract are risk factors associated with bowel obstruction including:
- Abdominal cancers
- Prior surgeries or radiation therapy that left scar tissue or adhesions
What is bowel obstruction?
The bowel, or intestine, is the part of the digestive tract that absorbs nutrients from foods we eat. The residue of digested food passes through the bowel and is excreted during elimination, the final stage of digestion. This process can be interrupted or halted by the presence of a bowel obstruction, which is a blockage that prevents the passage of intestinal contents. The cause of the b...
