Effect Of Laparoscopic Sleeve Gastrectomy on Vitamin D, Parathormone and Calcium Levels

Obesity is likely to be the disease of the 21th century. The growth of obesity is worldwide, a pandemic, and has increased globally in the last 30 years. Developed countries were more affected, but developing countries have increasingly contributed to this epidemic as they continue to modernize.
