Weight Loss Surgery
Weight loss surgery (also know as bariatric surgery) is a procedure performed on the stomach or intestines to help with weight loss. It has been shown to be the most effective and long-lasting treatment for morbid obesity.
This type of surgery results in significant weight loss and helps prevent, improve or resolve more than 40 obesity-related diseases or conditions including type 2 diabetes, heart disease, obstructive sleep apnea and certain cancers.
Studies show that individuals with morbid obesity (BMI≥ 30) have a 50-100% increased risk of premature death compared to individuals of healthy weight. Clinical studies have demonstrated significant improvements in safety, showing that the risk of death is 0.1%, and the overall likelihood of major complications is about 4%.
Safety & Risks
Overall mortality rate is about 0.1% - less than gallbladder (0.7%) and hip replacement (0.93%) surgery - and overall likelihood of major complications is about 4.3%. Clinical evidence shows risks of morbid obesity outweigh risks of metabolic and bariatric surgery.
Studies show patients typically lose the most weight one-to-two years after surgery, and maintain substantial weight loss with improvements in obesity-related conditions. Patients may lose as much as 60% of excess weight six months after surgery, and 77% of excess weight as early as 12 months after surgery. On average, five years after surgery, patients maintain 50% of their excess weight loss.
Benefits of Weight Loss Surgery
These procedures improve or resolve more than 40 obesity-related diseases and conditions, including type 2 diabetes, heart disease, certain cancers, sleep apnea, GERD, high blood pressure, high cholesterol, sleep apnea and joint problems. Additional benefits include:
- 60% reduction in mortality from cancer, with the largest reductions seen in breast and colon cancers
- 56% reduction in mortality from coronary artery disease
- 92% reduction in mortality from type 2 diabetes
- 40% overall reduction in mortality in gastric bypass patient
