Large Bowel Obstruction is a condition in which the normal passage of stool, gas, and intestinal contents through the large intestine (colon) becomes partially or completely blocked. Common causes include colorectal cancer, diverticular disease, volvulus (twisting of the bowel), strictures, fecal impaction, or inflammatory bowel conditions. Symptoms may include abdominal pain and distension, constipation, inability to pass stool or gas, nausea, vomiting, and changes in bowel habits. If left untreated, the obstruction can lead to bowel perforation, infection, compromised blood supply, and other life-threatening complications.
