Non-ulcer dyspepsia

During the last decade a new disease entity numbered among functional disorders of the digestive tract and defined as "non-ulcer dyspepsia", has been isolated. This disease is diagnosed most frequently at the age of 20 to 40 years. In West-European countries it is diagnosed in about 30% of out patients. Symptomatology of the disease is very ample and is, after exclusion of organic diseases of the digestive tract, the basis of diagnosis and classification. Present knowledge on the pathophysiology of "non-ulcer dyspepsia" is incomplete and based mainly on study results of the motility of the stomach and small intestine under manometric examination. In spite of that one attains satisfactory therapeutical effects during a prolonged administration of prokinetic drugs (dopamine receptor antagonists and peripheral parasympathomimetics).
