What is weight loss surgery (bariatric surgery)?

Weight loss surgery, also known as bariatric surgery, is a medical procedure performed on individuals who are severely overweight or obese and have not been successful in losing weight through other methods such as diet, exercise, and medication. The primary goal of bariatric surgery is to reduce the size of the stomach or modify the digestive system in a way that promotes weight loss.

There are several types of surgical and nonsurgical bariatric procedures. Our nationally recognized and highly experienced team will expertly guide you as you evaluate the weight loss surgical treatment that suits your lifestyle and overall health.

Bariatric surgery is usually considered as a last resort for individuals who have been unable to lose weight through other means and who have serious health risks due to obesity, such as type 2 diabetes, heart disease, high blood pressure, or sleep apnea. However, it's important to note that bariatric surgery is not a quick fix and requires significant lifestyle changes, including dietary modifications and regular exercise, to achieve and maintain weight loss. It also carries risks and potential complications, so it's essential for individuals considering bariatric surgery to thoroughly discuss the benefits and risks with their healthcare provider.

Weight loss surgery is not the 'easy way.' It's not a cure – it's a tool. One reason I was success after surgery was the support; I never felt alone in the process.
