At Bariatric Guru in Los Angeles, we offer Mini-Gastric Bypass (One-Anastomosis Gastric Bypass) as an effective solution for those seeking significant weight loss and improved health. Led by the renowned Dr. Sepehr Lalezari, our team specializes in advanced bariatric procedures tailored to meet the unique needs of each patient.
What is Mini-Gastric Bypass?
Mini-Gastric Bypass, also known as One-Anastomosis Gastric Bypass, is a bariatric surgery designed to promote substantial weight loss by creating a long, narrow stomach pouch and attaching it directly to the small intestine. This procedure simplifies the traditional gastric bypass by requiring only one surgical connection (anastomosis), making it a less complex surgery with a shorter operation time.
The Mini-Gastric Bypass procedure involves creating a long, narrow stomach pouch from the upper part of the stomach and connecting it directly to a loop of the small intestine. This effectively bypasses a significant portion of the stomach and the initial part of the small intestine, reducing the area where food is digested and absorbed.
How Does Mini-Gastric Bypass Work?
The mechanism of Mini-Gastric Bypass includes both restrictive and malabsorptive elements. By reducing the size of the stomach, the amount of food intake is limited, while the bypassed portion of the small intestine reduces the absorption of calories and nutrients. Additionally, this alteration in the digestive system leads to beneficial changes in gut hormones, aiding in further weight loss and appetite control.
Expected Weight Loss
Patients undergoing Mini-Gastric Bypass can expect to lose about 60-75% of their excess weight within the first two years following the procedure. This significant weight loss can lead to improved overall health and a reduction in obesity-related conditions.
Benefits of Mini-Gastric Bypass
- Effective Weight Loss

The procedure is less complex, typically resulting in a shorter operation time and quicker recovery.

Risks and Considerations
As with any surgical procedure, Mini-Gastric Bypass carries potential risks and complications. These may include:
- Risk of Bile Reflux
There is a possibility of bile flowing back into the stomach, which can cause discomfort and other complications.
- Nutritional Deficiencies
Due to reduced absorption of nutrients, patients may experience deficiencies in vitamins and minerals, requiring lifelong supplementation.
- Surgical Complications
Risks include infections, leakage at the surgical connections, and other typical surgical risks.
