[Peptic ulcer disease and primary hyperparathyroidism (author's transl)].

The causal relationship of primary hyperparathyroidism and ulcer disease is reviewed. In contrast to earlier ideas careful clinical and clinico-chemical investigations have shown that in patients with manifest primary hyperparathyroidism neither is the incidence of ulcer disease raised nor are deviations from the normal behavior of acid secretion or the serum gastrin level to be observed in comparison with the average population.
