Please help me? what is bowel obstruction?

Intestinal blockage: Bowel obstruction can involve either the small or large intestine. There are many causes of obstruction - for the large intestine, masses including cancer, inflammation or twisting (volvulus), for the small intestine, scar tissue from previous surgery, congenital twisting, congenital band, tumor or hernia. Partial obstruction may resolve without surgery but complete obstruction requires surgery.

Intestine: Is basically a tube with lots of curves in them. When it kinks, caused by adhesions or hernias, it can block off. When there is a growth inside the tube, like a tumor or cancer, it can block off. When it blocks off, it is called bowel obstruction.
