What is Weight loss surgery?
what is weight loss surgery and what are the benefits?
Surgery for weight loss (bariatric surgery) aims to reduce weight and improve medical conditions which are associated with obesity.28 Weight loss surgery works by increasing your sense of fullness after eating.34
Your doctor may consider bariatric surgery if you have some of the following conditions:
- Able to understand the risks associated with the surgery
- Committed to required lifestyle changes and follow-up care
- BMI is greater than 40
- OR BMI 30+ if there is an associated illness, e.g.type 2 diabetes or sleep apnoea, that may improve with weight loss
- OR BMI 30+ with inadequately controlled type 2 diabetes despite lifestyle and optimal medical therapy
HOW WELL DOES WEIGHT LOSS SURGERY WORK?
There are three main BENEFITS to weight loss surgery:
- Weight loss
- Improvement in associated medical conditions
- Improvement to your quality of life.
Studies have shown that surgery leads to the greatest and most sustained weight loss outcomes of all weight loss strategies.36
Amongst people with type 2 diabetes having bariatric surgery, 31-77% achieve normal blood sugar without diabetes medication and 80% maintain good glycaemic control with reduced or no medication.37
DID YOU KNOW?
Despite your best efforts, your body senses weight loss and actively works to return you to your starting weight.
- Changes to the hormones which control your hunger and fullness work to push your weight back up.12
- Your doctor can assess a wide range of things that may be influencing your health. Together you can then decide on the best approach for you to lose weight and improve your health.38
