Welcome To Arch Bariatrics of St. Louis


Obesity is a major health challenge with no simple solution. For people with obesity, weight loss based solely on lifestyle changes can be very difficult to achieve and even more challenging to maintain.

At Arch Bariatrics of St. Louis, we believe that obesity is a disease, which requires multidimensional approach to treatment including bariatric surgery to achieve long-term weight loss. Our team of Bariatric Surgeons and dieticians partner with you in defeating obesity and maintaining long-term weight loss.

Bariatric surgery causes weight loss by a combination of anatomical changes to the stomach and/ or intestine. These in turn reduce the size of the stomach, decrease food absorption and change some chemicals (hormonal changes) in the body. All of this effectively help to lose weight and correct the medical co morbidities.

Bariatric Surgery or Weight loss surgery is now commonly performed by laparoscopy or minimally invasive techniques. Gastric Bypass, Sleeve Gastrectomy, Gastric Band (LAP-BAND) and Bariatric Revision Surgery are the most common weight loss surgeries done by the bariatric surgeons for weight loss.

Whether you are thinking about weight loss surgery, such as Gastric BypassSleeve GastrectomyGastric Band (LAP-BAND) or are interested in pursuing non-surgical weight loss with Gastric Balloon, nutrition counseling, you’ve taken an important first step.

Bariatric/weight loss surgery is advised only in patients who meet certain criteria. Please contact us to schedule an appointment with our bariatric surgeon to discuss if you qualify for weight loss surgery.
