Is bowel obstruction a common disease? Is it dangerous? What are the symptoms and treatment methods? Bowel obstruction is the blockage of the intestines, which hinders normal digestive function. It is a common ailment with many causes, including the twisting of a section of healthy intestine, inflammation, side effects of surgery, or cancerous tumors. Symptoms include intermittent pain, weak排气(exhaustion), constipation, and increasingly severe vomiting (not necessarily present from the beginning).
