About this study
Official title: The Impact of Bariatric Surgery on Estimated Bone Mineral Density in Chinese Obesity Patients: a Retrospective Cohort Study
Obesity and related metabolic diseases have become a chronic disease that is a threat to human health. Bariatric surgery can effectively and long-term reduce excess body weight and relieve related metabolic diseases, including type 2 diabetes. Laparoscopic gastric bypass surgery and laparoscopic sleeve gastrectomy are commonly used in bariatric surgery. Laparoscopic sleeve gastrectomy due to simple operation, good weight loss, and metabolic disease control effect, which is more widely used. However, there are several studies that show an increased chance of gastroesophageal reflux disease after laparoscopic sleeve gastrectomy. Long-term gastroesophageal reflux may lead to Barrett's esophagus or esophageal cancer. Nowadays, the cause of gastroesophageal reflux disease after sleeve gastrectomy is not clear and precautionary measures are not precise.
In this study, prospective randomized controlled trials were conducted to explore the possible causes of bone mineral after bariatric surgery and to explore ways to prevent bone mineral after bariatric surgery.
