Patients who undergo malabsorptive bariatric surgery have a high incidence of mild hypocalcemia and seem to be at increased risk for developing severe symptomatic hypocalcemia after thyroid surgery. We describe 2 patients who underwent prior Roux-en-Y gastric bypass procedures who later had thyroid surgery that was complicated by severe hypocalcemia in the postoperative period. We also emphasize the importance of screening patients for thyroid disease and of completing any necessary thyroid procedures before bariatric surgery to avoid this serious complication.
