K90: Intestinal malabsorption

K90.8: Other intestinal malabsorption

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 The large intestine (colon) is where water and salt are withdrawn from the stool.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.

There can be many different reasons why you have poor nutrient absorption. You may not tolerate certain foods. The small intestine may also have been damaged by another disease. If the small intestine is damaged by another disease, it will not absorb nutrients so well. For example, you may get diarrhea. You may have also become infected with certain bacteria. As a result, you may have other symptoms as well.
