Adjustable gastric banding is considered to be one of the least invasive surgery for weight loss. The procedure involves placing an implant, a soft silicone ring with an expandable balloon around the upper part of the stomach. A person eats enough food only to fill the top part of the stomach. Over time, after the meal, the food passes through the opening of the band into the remainder of the stomach, and digestion continues normally. This way you will feel fuller much sooner and can prevent yourself from overeating.
If the operation is successful, you are expected to achieve long-term weight loss results. However, this heavily depends on your ability to keep up with your new lifestyle. Long-term weight loss should improve any obesity-related health problems you may have such as heart disease, high blood pressure, sleep apnea and type 2 diabetes.
