Diagnosis
The diagnosis of a stomach flu is usually made quite simply on the basis of the symptoms. Which pathogen causes the inflammation is usually irrelevant, since in most cases they all heal within a few days. Only if the diarrhea and the symptoms persist, the specific pathogen is filtered out of a stool sample and determined, so that a special therapy can be initiated.
A coeliac condition can often be guessed from the history of the affected person. Parents report the onset of the symptoms since the child started eating the first cereal products. A blood test usually provides final clarity.
The blood of affected people often contains antibodies which, as part of our immune system, cause the inflammation in the intestine. These special antibodies are directed against the so-called endomysium, the gliadin and the so-called tissue transglutaminase. A sample taken during a colonoscopy can also provide clarity.
The diagnosis of Crohn’s disease is made on the basis of various examinations. Colonoscopy, X-rays, ultrasound, blood and stool tests play a decisive role in this process. During colonoscopy, it is the extensive, “map-like” inflammation that is most impressive, since almost never entire sections of the intestine are affected. In order to diagnose inflammation of the small intestine, the MRI according to Sellink has recently become established. After the administration of contrast medium, an MRI of the small intestine is performed, which shows changes in the mucous membrane very well.
Prognosis
The course of Crohn’s disease is highly variable and varies from patient to patient. If the patient adheres to the therapy sufficiently, the prognosis for Crohn’s disease is good and about 50% of those affected can live without symptoms. Life expectancy is not limited by the disease.
Celiac disease is also lifelong and can only be alleviated but not cured. An untreated celiac disease increases the risk of tumor development within the digestive tract. However, a gluten-free diet can reduce the risk of long-term damage almost to a minimum and keep the damage in the intestine to a minimum.
