Nausea, stomach pain, bloating. As well as diarrhea, constipation and flatulence.

The complaints are often harmless and disappear after a few days. If they persist for a long time or recur repeatedly, the cause should be clarified medically. This is usually a challenge, because stomach and intestinal complaints are manifold. As varied as their triggers: stress, diet and lifestyle play a major role. In addition, infections, inflammations or cancer can be the cause of problems in the gastrointestinal tract. It is important to recognise the cause early on in order to be able to treat them successfully. We offer numerous examinations for this purpose. In addition to the selection on this page, you will find all tests in our test list.



With nausea, diarrhoea and vomiting, gastro-intestinal infections announce themselves. Usually the symptoms come as quickly as they go. Gastro-intestinal infections are among the most common infectious diseases worldwide. Almost everyone falls ill with diarrhoea and vomiting at least once in their lifetime. Often even several times. Campylobacter, noroviruses, salmonella and parasites are among the most common causes. Our comprehensive stool diagnostics examine for numerous pathogens.



Colon cancer often develops from intestinal polyps. In addition to certain previous diseases and genetic factors, an unhealthy lifestyle is also considered a risk factor. Stomach cancer can be caused by certain stomach diseases, diet or genetic factors. As with all types of cancer, early detection of stomach and intestinal tumours is considered the best chance of cure. We offer various parameters for this purpose. Does a tumor occur at a young age? You suspect a hereditary cause? Then you will find support in the clarification of hereditary tumours.



More than two million Europeans live with chronic inflammatory bowel diseases. The causes are manifold. It is important to clearly distinguish the possible triggers. Calprotectin is a gentle, non-invasive marker for the differential diagnostic differentiation of functional from chronic inflammatory and neoplastic changes of the intestine. For the diagnosis and follow up of acute inflammations  and also to differentiate between bacterial and viral infections we recommend the analysis of C reactive protein (CRP).
