Why Surgery?
Many patients seek help with weight loss through fad diets, pills, and exercise programs. Often they lose some weight, but experience weight regain when the diet is over. Over time, they may even gain more weight back than they lost in the first place. As more time goes by, these patients may develop obesity-related illnesses that make it even more difficult to diet and exercise. For those patients with a body mass index (BMI) of 40 or more (about 100 pounds overweight) or those with a BMI between 35 and 40 and one or more obesity-related illnesses, weight loss surgery may be the best choice.
The decision to have weight loss surgery is a big one! It will change your life in a very positive, but often irreversible, way. You will begin to see food in a very different light. You will begin to examine your food behaviors for what they are – responses to emotion or stress. Patients begin to use food to help them live a healthy, active lifestyle. Many patients are able to stop taking some of the medications that are taking to manage their obesity-related illnesses, as they no longer need them. A recent study that included over 22,000 weight loss surgery patients showed that as many as 83.6% achieved a resolution of their Type 2 Diabetes and were able to stop all diabetes medication.
