[Does allergy of the digestive tract exist? (author's transl)].

Factors which set up an allergy of the digestive tract are alimentary antigens, fungal or bacterial antigens, drugs, among other things. The allergy is favored by achlorhydria, lack of pancreatic or duodenal enzymes or inflammations of the gastro-intestinal mucosa. The origin of a digestive allergy quite decisively depends on the A immunoglobulins. They can combine with high molecular weight antigens and so inhibit the transit of the active antigen. In the diagnosis, the authors have found a test particularly useful in which a few drops of antigen solution are administered sublingually. Therapy includes restoration of disturbed digestive functions, an individually planned diet and the avoidance of alcohol and strong spices.
