K91: Postprocedural disorders of digestive system, not elsewhere classified
K91.2: Postsurgical malabsorption, not elsewhere classified
The stomach is located in the upper left abdomen. The stomach stores food and breaks it down further. Harmful pathogens are also killed by gastric acid in the stomach. The stomach thus prepares the food for digestion in the intestines.
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 The large intestine (colon) is where water and salt are withdrawn from the stool.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.
One part of your stomach or intestines was removed. Because of that, you are no longer able to properly absorb the individual nutrients from food. For example, you may have diarrhea or have to vomit. You also sometimes lose weight. It is also possible that the body is absorbing insufficient minerals such as calcium or iron. You may then have problems with your bones or blood formation.
