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

Effect Of Laparoscopic Sleeve Gastrectomy (LSG) 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. The national and global burden of obesity, with its public health and financial implications, is projected to increase markedly in the next two decades.

the study aimed to assess the effect of Vit D supplementation on preventing altered levels of calcium, Vit D, and parathormone after laparoscopic sleeve gastrectomy.
