Dietary Intake After Laparoscopic Sleeve Gastrectomy -a 5 Year Study

Weight Loss and Metabolic Surgery Center Min-Sheng General Hospital

Weight reducing surgery is the only effective therapy for morbid obese patients.

Sleeve gastrectomy is a popular choice for bariatric surgery because of less sequela. There is poor knowledge about the nutritional status inpatients after LSG. The aim of our study was to investigate the relationship between dietary intake and weight loss after LSG.

Weight reducing surgery is the only effective therapy for morbid obese patients. Restrictive type surgery is safer than mal-absorptive type surgery. Laparoscopic sleeve gastrectomy is an effective surgery. In laparoscopic sleeve gastrectomy (LSG), about 90% of the stomach is surgically removed by vertical resection of the great curvature side, including the fundus. The simplicity of surgical procedures, the low occurrence of complications, and the efficiency of reducing excess weight have made LSG as a popular choice for bariatric surgery. After LSG, the amount of food eaten is drastically reduced, leading to nutritional deficiencies potentially. There is poor knowledge about the nutritional status inpatients after LSG. Some literatures suggest that LSG results in less nutritional deficiencies than Roux-en-Y gastric bypass. The aim of our study was to investigate the relationship between dietary intake and weight loss after LSG.
