K59: Other functional intestinal disorders
K59.3: Megacolon, not elsewhere classified
The large intestine (colon) is like an upside down U in the abdomen. The first part lies in the lower right corner of the abdomen. Then it continues upwards and runs across from right to left. Then it descends again. There then follows an S-shaped part located on the bottom left side of the abdomen, which then merges into the rectum. The rectum is the last section of the large intestine (colon).
Parts of your large intestine are enlarged. The large intestine can become enlarged for various reasons. For example, the large intestine may become enlarged if it is obstructed or constricted in a particular place. The parts of the large intestine in front of the constriction may then become enlarged. The large intestine may also become enlarged if it is constantly inflamed. The inflammation can result in the large intestine no longer being able to contract and relax properly.
If the large intestine is enlarged, this can cause various symptoms. You may have severe abdominal pain, for example.
