Serum Fat-Soluble Vitamin Deficiency And Abnormal Calcium Metabolism After Malabsorptive Bariatric Surgery

Weight loss after biliopancreatic diversion or duodenal switch gastric bypass is due to decreased calorie absorption secondary to fat malabsorption. Fat malabsorption may also cause essential fat-soluble vitamin deficiencies, which may have severe clinical consequences and alter calcium metabolism.

Method

Serum vitamins A, D, E, and K, zinc, parathyroid hormone, corrected calcium, and alkaline phosphatase levels were measured in a cohort of patients who had previously undergone biliopancreatic diversion gastric bypass surgeries. Two bariatric surgery units were involved in the study: New York University School of Medicine (New York, NY), and the Wesley Medical Center (Brisbane, Australia). A total of 170 patients completed the study.

Results

The incidence of vitamin A deficiency was 69%, vitamin K deficiency 68%, and vitamin D deficiency 63% by the fourth year after surgery. The incidence of vitamin E and zinc deficiency did not increase with time after surgery. The incidence of hypocalcemia increased from 15% to 48% over the study period with a corresponding increase in serum parathyroid hormone values in 69% of patients in the fourth postoperative year.

Conclusion

There is a progressive increase in the incidence and severity of hypovitaminemia A, D, and K with time after biliopancreatic diversion and duodenal switch gastric bypass surgery. Calcium metabolism is affected with an increasing incidence of secondary hyperparathyrodisim and evidence of increased bone resorption in 3% of patients. Long-term nutritional monitoring is necessary after malabsorptive bypass operations for morbid obesity.

Laparoscopic or open bariatric surgery, such as gastric banding or bypass is not an easy solution to morbid obesity and weight loss. It is a serious surgical procedure, involving health risks. To produce lasting weight loss it requires a long-term patient commitment to eating a healthy diet and following a regular program of physical exercise. Life-long use of nutritional supplements may also be necessary. So, before deciding, discuss your options fully with your doctor. © 2003-2017 Bariatric-Surgery.Info - Terms - Contact - Information - Resources
