[Symptoms in the digestive tract for diseases of other organs].

Gastrointestinal symptoms in elderly patients are not only caused by primary diseases of the digestive organs. Even a healthy digestive tract commensurate with the age of the patient is affected by age and disease-related changes of other organs, in particular those of the cardiovascular and metabolic systems. This leads to a broad spectrum of secondary dysfunctions of the gastrointestinal tract.
