What is Bariatric Surgery?

Bariatric surgery is a group of minimally invasive procedures that change the stomach, and sometimes the small intestine, to support significant, lasting weight loss and improve obesity-related conditions such as type 2 diabetes and sleep apnea. At Oneka Bariatrics & Wellness in Atlanta, Dr. Shani Belgrave, MD, FACS, FASMBS, performs the gastric sleeve (VSG), gastric bypass (Roux-en-Y), endoscopic sleeve gastroplasty (ESG), revision surgery, and transoral outlet reduction (TORe). Typical weight loss is about 60% of excess weight for the sleeve and 70% for the bypass, though results vary and are never guaranteed. Call (470) 250-0035.
If you are just starting to explore weight-loss surgery, this guide explains what bariatric surgery is, the main types, who it helps, and how to think about choosing. At Oneka, the goal is to give you clear information first, so you can make a confident decision.

How does bariatric surgery work?

Bariatric procedures work by limiting how much you can eat, changing hunger and fullness signals, and in some cases changing how the body absorbs calories. The result, for most patients, is significant and durable weight loss along with improvement in conditions tied to excess weight. The procedures are performed minimally invasively.

The main types of bariatric surgery

The gastric sleeve (VSG) removes part of the stomach to create a smaller, sleeve-shaped stomach. The gastric bypass (Roux-en-Y) makes a small pouch and reroutes the intestine, and is itself an anti-reflux operation. The endoscopic sleeve gastroplasty (ESG) is an incisionless option that stitches the stomach smaller. Oneka also offers revision surgery and transoral outlet reduction (TORe) for weight regain.

Is bariatric surgery effective for obesity?

Bariatric surgery is one of the most effective long-term treatments for obesity. Typical weight loss is about 60% of excess body weight for the sleeve and about 70% for the bypass, though results vary by patient and are never guaranteed. It works best alongside nutrition and lifelong follow-up, which is why Oneka pairs surgery with its programs.

Conditions it can improve

Lasting weight loss can improve type 2 diabetes, sleep apnea, high blood pressure, GERD, PCOS, fatty liver, and joint pain and mobility. We describe these outcomes as improvement or remission, never cure, since results depend on the individual.

How do I know which procedure is right for me?

The right procedure depends on your weight, your health conditions such as reflux or diabetes, and your goals. There is no single best operation for everyone. Dr. Belgrave reviews your history at consultation and helps you choose, including whether a non-surgical path might suit you better.

A clear definition

Bariatric surgery is a group of minimally invasive procedures that change the stomach, and sometimes the small intestine, to support significant, lasting weight loss and improve obesity-related conditions. At Oneka Bariatrics & Wellness in Atlanta, these are performed by board-certified surgeon Dr. Shani Belgrave.

The procedures Oneka offers

Oneka performs the gastric sleeve (VSG), gastric bypass (Roux-en-Y), endoscopic sleeve gastroplasty (ESG), revision surgery, and transoral outlet reduction (TORe). It does not offer lap-band, gastric balloon, duodenal switch, or SADI, and refers very complicated histories to an academic center.

Effective, with the right support

Bariatric surgery is among the most effective long-term obesity treatments, with typical loss around 60% of excess weight for the sleeve and 70% for the bypass. Results vary and are never guaranteed; Oneka pairs surgery with nutrition and mindset programs for lasting results.

  • A boutique practice where a real person answers and appointments are often within 24 hours.

Bariatric surgery for type 2 diabetes

Bariatric surgery, especially the gastric bypass, often strongly improves type 2 diabetes. Oneka frames this as improvement or remission, never cure, and Dr. Belgrave individualizes the recommendation with full review of your diabetes history.

Minimally invasive, faster recovery

Modern bariatric surgery is minimally invasive, so most sleeve patients go home the same day or within 23 hours with small incisions. This is a major change from older open surgery, and a reason recovery is faster than many patients expect.

When surgery is not the answer

Bariatric surgery is not right for everyone. Oneka also offers medical weight loss with GLP-1 medication from a BMI of 27 and lifestyle programs, so patients who are not surgical candidates still have effective, surgeon-led options.
