K56.0: Paralytic ileus

You have an intestinal obstruction.

The intestines are made up of the small intestine and the large intestine or colon. Most of the nutrients are absorbed in the small intestine. The large intestine (colon) is where water and salt are withdrawn from the stool. The last segment of the large intestine (colon) is the rectum. Stool then leaves the body through the anus.

Various nerves control the muscles in the intestines. Your intestinal nerves are currently not working properly. If the intestinal nerves are no longer working properly, the intestinal muscles will be paralyzed. If the intestinal muscles are no longer able to properly convey the intestinal contents through the intestines, these contents may be jammed and clog the intestines. This is also called an intestinal obstruction or ileus.

If you have an intestinal obstruction, you may vomit. Your abdomen may be thicker than normal, because you have a lot of air, feces and fluid in your intestines. If you have an intestinal obstruction, you may be very sick.
