[The aging alimentary tract (author's transl)].
The physiological process of aging causes changes in volumen and composition of saliva, gastric and pancreatic juice and bile flow, a diminished absorption and an altered bacterial flora. However, these changes are compensated and do not cause symptoms. Besides of an increased disposition to develop carcinoma of the gut the alimentary tract in contrast to the cardiovascular system has no specific symptomatology as signs of wear. In old age, too, functional disorders rank first in clinical symptomatology.
