Primary hyperparathyroidism and the gastrointestinal tract.
To determine the frequency of gastrointestinal symptoms in primary hyperparathyroidism, we retrospectively analyzed 100 consecutive patients seen at Emory University Hospital from Jan 1, 1977 through March 1, 1979. At the time of diagnosis, 28 patients complained of nausea, 19 of vomiting, 29 of abdominal pain, and 33 of constipation. One patient presented with acute pancreatitis and 14 had ulcer disease (two gastric and 12 duodenal ulcers). Hypercalcemia increases gastric acid secretion and may account for associated ulcer disease and the ulcer-like pain in primary hyperparathyroidism. The mechanisms causing the other gastrointestinal symptoms in hypercalcemia remain to be elucidated. These symptoms abate on correction of hyperparathyroidism.
