title: [Abnormal calcium metabolism in the remote period after bariatric surgery].
abstract: Calcium metabolism in the long-term period after bariatric surgery is reviewed in the present article. The study of calcium metabolism parameters and vitamin D status was performed in The Endocrinology Research Center. Morbidly obese patients (BMI > 40) were included in the 1st group (n = 22), patients who underwent biliopancreatic diversion for morbid obesity (n = 23) were included in the 2nd group, healthy normal weight controls (n = 22) were included in the 3rd group. 25 (OH) D level was different in the 3 groups (p < 0.001). Vitamin D deficiency prevailed in morbidly obese patients compared to healthy controls (p = 0.007). Elevated parathyroid hormone (PTH) level was found in 4 (18%) morbidly obese patients, in 12 (52%) operated patients. Not a single case of PTH over reference interval was found in the controls. The frequency of secondary hyperparathyroidism was significantly higher in the operated patients.
