Irritable colon syndrome is a frequent diagnosis in outpatients of general
practitioners. At least one third of all patients with abdominal complaints
suffer from the irritable colon sydrome. Local factors, central control me
chanisms and psychic stress reactions are responsible for the development a
nd persistence of the complaints. Differential diagnosis is important to di
fferentiate the syndrome from other psychic diseases. Drug therapy may be a
pplied for a short period of time only: drug therapy alone is insufficient.
Nutritional counselling, relaxation and in some cases also psychotherapies
are the treatments of choice after adequate diagnostics.
