The mini gastric bypass, also known as the One Anastomosis Gastric Bypass, is a weight loss surgery that combines aspects of both gastric bypass and sleeve gastrectomy. It is designed to help patients lose weight by restricting food intake and reducing the body’s ability to absorb calories. The procedure involves creating a small pouch from the stomach and rerouting the small intestine to this pouch, leading to reduced food intake and decreased calorie absorption.

How Its Done
Similar to the standard gastric bypass, the first step of the mini gastric bypass procedure involves creating a small stomach pouch. The surgeon removes a portion of the stomach and forms a pouch about the size of an egg. This pouch significantly limits the amount of food that can be consumed at once, helping to reduce overall food intake.
After the pouch is created, the surgeon reroutes the small intestine to connect it to the newly formed stomach pouch. The rerouting involves bypassing a portion of the small intestine, reducing the area where food is absorbed. This results in fewer calories and nutrients being absorbed by the body, contributing to weight loss. Unlike traditional gastric bypass, where two connections (anastomoses) are made, the mini gastric bypass uses only a single anastomosis, simplifying the process and reducing potential complications.
The surgery is typically performed laparoscopically, meaning it is minimally invasive. Small incisions are made in the abdomen, and a camera (laparoscope) is used to guide the surgeon throughout the procedure. This approach results in quicker recovery times, reduced risk of complications, and less post-surgical discomfort compared to traditional open surgery.

Potential Risks
Before considering the mini gastric bypass, it is important to be familiar with the potential risks of bariatric procedures. Risks vary based on the health of the patient.
- Minor Complications
- Major Complications
Minor Complications
UNCOMMON AND CAN BE MANAGED FAIRLY EASILY
- Minor wound or skin infection
- Excess / loose skin
- Vomiting or nausea
- Acid reflux (heartburn)
- Changes in bowel habits like constipation, diarrhea, bloating, cramping, or gas
- Gastric ulcer or anastomotic stricture
- Development of gallstones or gallbladder disease
- Nutritional deficiencies as a result of food bypassing the stomach
- Dumping syndrome when high sugar foods move too fast from the stomach to the small intestine
Major Complications
COMPLICATIONS COULD RESULT IN RE-OPERATION
- Internal Bleeding
- Intestinal obstruction
- Blood clots in the legs or lungs
- Internal hernia
- Perforation of stomach/intestine or leakage
Gastric Bypass FAQs
How does the mini gastric bypass differ from the gastric bypass?
The mini gastric bypass differs from the traditional gastric bypass primarily in the surgical technique and the number of connections made during the procedure. In the mini gastric bypass, the surgeon creates a single connection between the stomach pouch and the small intestine, known as a single anastomosis. This contrasts with the traditional gastric bypass, which involves creating two connections: one between the stomach pouch and the small intestine and another for the bile and pancreatic enzymes to flow into the intestine.
The mini gastric bypass is simpler and quicker than a regular gastric bypass, as it involves a single anastomosis (connection between the stomach and intestine), compared to the multiple anastomoses in the traditional gastric bypass. This often leads to a faster recovery time and fewer complications.
Why would I want the mini gastric bypass vs. the standard gastric bypass?
The mini gastric bypass may be preferred over the traditional gastric bypass for several reasons. First, the mini gastric bypass is a simpler and quicker procedure because it involves only one connection (anastomosis) between the stomach pouch and the small intestine, compared to two in the traditional gastric bypass. This makes the mini gastric bypass less complex and may result in a shorter surgery time, reducing the risk of complications. Additionally, mini gastric bypass tends to have a faster recovery time, with many patients returning to normal activities within a few weeks.
Another benefit is that the mini gastric bypass generally requires fewer long-term adjustments and may be associated with a lower risk of complications, such as bowel obstruction, which is sometimes seen in the traditional gastric bypass due to its more complex rearrangement of the intestines. Both procedures result in significant weight loss, but the mini gastric bypass may be a more attractive option for those seeking a less invasive and quicker recovery experience. However, the decision should be made in consultation with a qualified surgeon, who will evaluate your individual health needs and goals.
How much weight will I lose after mini gastric bypass surgery?
Research shows that patients will lose between 60 and 80% of their excess weight. Patients who achieve greater success after gastric bypass surgery are those individuals who follow their surgeon and dietitians' instructions and incorporate exercise into their daily activities.
Is the mini gastric bypass reversible?
No, the mini gastric bypass is not reversible. It permanently alters the anatomy of the stomach and small intestine, which reduces the amount of food that can be consumed and the calories absorbed.
