Weight Loss Surgery
Weight loss surgery, often referred to as bariatric surgery (which is a surgical procedure performed on the stomach or intestines to induce weight loss) has been shown to be the most effective and durable 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 or 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
