Mini Gastric Bypass
Fast. Effective. Economical
Mini Gastric Bypass Surgery
Mini Gastric Bypass (MGB), also known as One-Anastomosis Gastric Bypass (OAGB), is one of the most efficient and least invasive bariatric procedures. Known for its shorter operation time, faster recovery, and high success rates in treating obesity and metabolic conditions such as Type 2 diabetes, hypertension, and hyperlipidemia, it has become a preferred option for many international patients.

What is Mini Gastric Bypass Surgery?
Mini Gastric Bypass is a laparoscopic bariatric surgery that combines the principles of both gastric sleeve and traditional gastric bypass. During the procedure:
- A long, narrow gastric pouch is created from the existing stomach.
- This pouch is then directly connected to a loop of the small intestine, bypassing a portion of the stomach and duodenum.
This rerouting reduces calorie absorption while also restricting food intake—leading to significant weight loss.

Key Advantages of Mini Gastric Bypass
- Simpler Procedure: Only one connection (anastomosis) is made, making it faster and technically simpler than Roux-en-Y gastric bypass.
- Shorter Surgery & Recovery Time: Operation time is shorter, typically 60–90 minutes. Most patients stay in the hospital for just 3–4 days.
- Effective Weight Loss: Comparable or superior to traditional gastric bypass in terms of total body weight loss and improvement in comorbidities.
- Improvement in Metabolic Conditions: Proven benefits in resolving or improving Type 2 diabetes, high blood pressure, sleep apnea, and cholesterol levels.
- Cost-Effective: With all-inclusive packages and high medical standards, Turkey offers excellent value for MGB surgery.
Procedure Details
- Anesthesia: Performed under general anesthesia.
- Laparoscopic Technique: Small incisions, minimal scarring, faster healing.
- Gastric Pouch Creation: Top part of the stomach is sectioned to create a sleeve-like pouch.
- Intestinal Bypass: The pouch is connected to the small intestine, bypassing part of the digestive tract.
- Closure & Recovery: Surgery takes 1–1.5 hours; early mobility is encouraged within 24 hours.
Risks & Considerations
While Mini Gastric Bypass is safe and effective, it’s still a major surgery. Potential risks include:
- Dumping syndrome (nausea, diarrhea after eating)
- Bile reflux gastritis (due to bypassed pyloric valve)
- Nutritional deficiencies (lifelong vitamin & mineral supplementation required)
- Inaccessibility of the bypassed stomach for future endoscopy
- Surgical risks: bleeding, infection, anesthesia complications
Important Note: Patients with a family history of stomach cancer must be evaluated carefully before undergoing MGB.
Who is a Candidate?
- BMI ≥ 40
- BMI 35–40 with obesity-related conditions (diabetes, hypertension, sleep apnea)
- Age 18–65 (exceptions considered case-by-case)
- Failed previous attempts at weight loss via diet and exercise
- Committed to long-term lifestyle and dietary changes
Life After Mini Gastric Bypass
- Hospital Stay: 3–4 days, including 1–2 days in ICU for observation
- Nasal tube: May be placed for 2–3 days post-surgery
- Vitamin monitoring: Regular 3-month checks for 1–2 years
- Gradual diet: Liquid → pureed → soft → solid
- Ongoing support: Dietitian consultations and long-term monitoring
Mini Gastric Bypass vs. Gastric Bypass
| Feature | Mini Gastric Bypass | Roux-en-Y Gastric Bypass |
|---|---|---|
| Anastomoses (Connections) | 1 | 2 |
| Surgery Time | Shorter | Longer |
| Risk of Bile Reflux | Higher | Lower |
| Nutritional Deficiencies | Possible | Possible |
| Reversibility | Relatively easier | More complex |
| Endoscopic Access to Stomach | No | No |
Alternatives to Mini Gastric Bypass
- Gastric Sleeve Surgery: Reshapes the stomach into a tube shape by removing ~80% of it.
- Gastric Balloon / Swallowable Balloon: Non-surgical, short-term options to reduce food intake.
- Gastric Bypass (RNY): More complex procedure involving two intestinal reconnections.

Frequently Asked Questions
Mini Gastric Bypass (MGB) is a bariatric surgery that involves creating a small stomach pouch and connecting it directly to the small intestine. This reduces food intake and limits calorie absorption, helping patients achieve significant weight loss.
Mini Gastric Bypass involves only one intestinal connection (anastomosis), making it simpler and quicker than Roux-en-Y, which has two connections. However, MGB may carry a higher risk of bile reflux due to the single-loop construction.
Patients typically lose 60–85% of their excess weight within the first 12–18 months after surgery. Success depends on adherence to dietary and lifestyle changes.
You may be eligible if you:
Have a BMI of 40 or higher, or
Have a BMI between 35–40 with obesity-related health conditions (e.g., Type 2 diabetes, hypertension, sleep apnea).
A thorough medical evaluation is required to determine your eligibility.
Technically, yes. Since the surgery involves fewer anatomical changes compared to other procedures, it is considered more reversible. However, reversal is rarely recommended unless medically necessary.
Mini Gastric Bypass typically takes 60 to 90 minutes under general anesthesia. Most procedures are performed laparoscopically (minimally invasive).
Most patients stay in the hospital for 3 to 4 days. Initial monitoring may include a brief stay in the ICU and the use of a nasogastric tube for 2–3 days.
Yes. Because the surgery affects nutrient absorption, you will need lifelong supplementation with multivitamins, iron, calcium, vitamin B12, and other essential nutrients.
Bile reflux can occur in some patients, as the pyloric valve is bypassed in this surgery. Although not common, alkaline reflux gastritis is a known potential complication. Monitoring and medical treatment may be needed in rare cases.
Endoscopy of the bypassed (excluded) portion of the stomach is difficult. If there’s a strong family history of stomach cancer or other GI risks, this should be discussed in detail with your surgeon before surgery.
Recovery is relatively fast. You'll begin with a liquid diet, followed by pureed foods, and gradually transition to solids. Most people can return to light activities within 2–3 weeks, with full recovery in 4–6 weeks.
