what causes bowel obstruction
A bowel obstruction happens when either your small or large intestine is partly or completely blocked.ther causes include hernias and Crohn's disease, which can twist or narrow the intestine, and tumors, which can block the intestine. A blockage also can happen if one part of the intestine folds like a telescope into another part, which is called intussusception. In the large intestine, cancer is most often the cause.
