From an anatomical point of view, the stomach (technical term: ventriculus) is merely a stretchable, elastic muscle bag that connects to the esophagus and consists of the stomach mouth (cardia), stomach base (fundus), stomach body (corpus) and stomach outlet (antrum). It opens into the duodenum, the first section of the small intestine.

Sounds unspectacular, but the stomach has important tasks: it stores the food for a short time, starts digesting and then transfers the food to the small intestine in portions. The parietal cells in its mucous membrane produce stomach acid, which breaks down food and kills germs. The main cells form pepsinogens, which are activated by the acidic gastric juice and break down the proteins contained in the food pulp into smaller pieces.

Most people are familiar with temporary stomach problems: heartburn, nausea, stomach pain and a feeling of fullness can be symptoms. Often the symptoms are harmless and go away quickly. In other cases, especially if the symptoms are very severe, persist for a long time or keep recurring, a medical examination is necessary to clarify the causes.
