K91.1: Postgastric surgery syndromes

You have symptoms because you had stomach surgery.

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 stomach ensures that the food is released into the intestines in portions.

A part of your stomach was removed. As a result, your stomach is no longer able to release food into the intestines in portions. If you have then eaten too much at once, too much food may get into the intestines at once. You can then have various problems. You may even collapse.

Sometimes food contains many substances that bind water. If a large amount of such food suddenly gets into the intestines, a lot of water from the body will also get into them. As a result, you may have problems with your circulation. These symptoms occur rather suddenly after the ingestion of food.

If a large amount of food containing sugar suddenly gets into the intestines, the body releases a large amount of a specific messenger substance. Thanks to this messenger substance, the sugar level in the blood drops considerably after several hours. You may feel nauseated or sweat, for example.
