Bariatric surgery is a tool for those patients suffering from obesity. Fox 2 has your basics on different surgery procedures and qualifications.

The three most common bariatric weight loss surgery procedures are gastric bypass, sleeve gastrectomy and gastric bands (also known as the Lap Band).

The surgeon staples off a large part of the stomach, leaving a small pouch for patients to fill with food. The benefits are almost instant.

A Sleeve Gastrectomy removes 60 percent of the stomach and the gastric band procedure involves an adjustable band placed above the stomach all meant to reduce food intake.

To be a candidate for bariatric surgery, most insurance companies require a Body Mass Index of 35 and higher-which is considered morbidly obese, and one or more life-threatening diseases or conditions brought on by obesity such as type-2 diabetes or high blood pressure.

Out-of-pocket costs for bariatric surgery range anywhere from $15,000 to $35,000 depending your surgeon, facility and region.

Next week, we’ll have more on what life is like after bariatric surgery and the different programs facilities offer.
