What causes volvulus in human?

Volvulus is caused by the twisting of a portion of the intestine, which can lead to obstruction and reduced blood flow. Factors contributing to volvulus include anatomical abnormalities, such as a long mesentery, previous abdominal surgery, or conditions like megacolon. It can occur in various parts of the gastrointestinal tract but is most common in the sigmoid colon and the cecum. Symptoms typically include abdominal pain, bloating, and constipation, requiring prompt medical attention.
