One Anastomosis Gastric Bypass

Obesity is a chronic health condition that can lead to serious medical problems such as Type 2 diabetes, hypertension, sleep apnea, heart disease, fatty liver disease, and joint pain. When lifestyle modifications and medical treatments are not enough, OAGB (One Anastomosis Gastric Bypass) in Vasant Kunj offers an effective and long-term weight loss solution. Dr. Sanjay Verma provides advanced bariatric surgery using minimally invasive laparoscopic techniques, helping patients achieve sustainable weight loss and improve their overall health.

One Anastomosis Gastric Bypass (OAGB), also known as Mini Gastric Bypass (MGB), is a well-established bariatric procedure that combines restriction of food intake with reduced calorie absorption, making it an effective option for patients with severe obesity.

What Is OAGB (One Anastomosis Gastric Bypass)?

OAGB is a minimally invasive bariatric surgery in which a long, narrow stomach pouch is created, and a loop of the small intestine is connected directly to this pouch through a single surgical connection (anastomosis). This reduces the amount of food you can eat and decreases calorie absorption, resulting in significant and sustained weight loss.

Compared to traditional gastric bypass, OAGB involves only one intestinal connection, making the procedure technically simpler while providing excellent weight loss outcomes in appropriately selected patients.

The surgery is performed laparoscopically through small incisions, resulting in less pain, minimal scarring, and faster recovery.

Who Is a Candidate for OAGB?

You may be a suitable candidate if you:

• Have a Body Mass Index (BMI) of 40 kg/m² or higher.
• Have a BMI of 35 kg/m² or higher with obesity-related conditions such as diabetes or hypertension.
• Have not achieved lasting weight loss through diet, exercise, and medical management.
• Are committed to lifelong dietary and lifestyle changes.
• Are medically fit for bariatric surgery following a comprehensive evaluation.

Dr. Sanjay Verma carefully evaluates every patient to determine whether OAGB is the most appropriate bariatric procedure.

Conditions That May Improve After OAGB Surgery

Successful weight loss following OAGB may improve several obesity-related health conditions, including:

• Type 2 Diabetes
• High Blood Pressure
• High Cholesterol
• Obstructive Sleep Apnea
• Fatty Liver Disease
• Joint Pain and Osteoarthritis
• Polycystic Ovary Syndrome (PCOS)
• Reduced Mobility
• Increased Risk of Cardiovascular Disease

Many patients also experience better physical fitness, improved confidence, and an enhanced quality of life.

Benefits of OAGB Surgery

OAGB offers several important advantages, including:

• Significant and sustained weight loss
• Minimally invasive laparoscopic surgery
• Single intestinal connection
• Shorter operative time in many cases
• Smaller incisions with minimal scarring
• Improvement in obesity-related diseases
• Better blood sugar control
• Reduced appetite
• Faster recovery compared to open surgery
• Long-term improvement in overall health

How Is OAGB Performed?

The procedure is performed under general anesthesia.

Step 1: Preoperative Assessment

A comprehensive evaluation is carried out, including medical history, physical examination, blood investigations, nutritional assessment, imaging, and anesthetic clearance.

Step 2: Creating the Gastric Pouch

Using laparoscopic instruments, a long, narrow stomach pouch is created to reduce stomach capacity.

Step 3: Connecting the Small Intestine

A loop of the small intestine is connected to the newly created stomach pouch through a single anastomosis. This allows food to bypass part of the digestive tract, reducing calorie absorption.

Step 4: Recovery

After surgery, patients are monitored closely and encouraged to begin walking early. Most patients remain in the hospital for approximately two to three days.

Recovery After OAGB Surgery

Recovery is generally smooth when postoperative instructions are followed carefully.

Recovery usually includes:

• Walking within hours after surgery
• Initial liquid diet
• Gradual transition to soft and solid foods
• Regular follow-up visits
• Nutritional counseling
• Lifelong vitamin and mineral supplementation
• Gradual return to exercise

Most patients can return to light daily activities within two to three weeks, depending on their recovery.

Lifestyle Changes After OAGB

Long-term success depends on adopting healthy habits after surgery.

Patients should:

• Eat small, protein-rich meals
• Avoid overeating
• Stay well hydrated
• Exercise regularly
• Avoid sugary foods and carbonated beverages
• Take prescribed vitamin and mineral supplements
• Attend regular follow-up appointments
• Follow dietary guidance from the bariatric team

These lifestyle modifications help maintain weight loss and reduce the risk of nutritional deficiencies.

Frequently Asked Questions (FAQs)

1. What is OAGB?

OAGB (One Anastomosis Gastric Bypass), also called Mini Gastric Bypass, is a bariatric surgery that reduces stomach size and bypasses a portion of the small intestine to promote weight loss.

2. How is OAGB different from traditional Gastric Bypass?

OAGB uses a single intestinal connection, whereas Roux-en-Y Gastric Bypass uses two. The choice depends on the patient's condition and the surgeon's assessment.

3. Who is eligible for OAGB?

People with severe obesity or obesity-related medical conditions who have not achieved adequate weight loss through non-surgical methods may be suitable candidates after evaluation.

4. Is OAGB performed laparoscopically?

Yes. OAGB is generally performed using minimally invasive laparoscopic techniques.

5. How long is the hospital stay?

Most patients stay in the hospital for two to three days after surgery.

6. Will I need vitamin supplements after OAGB?

Yes. Lifelong vitamin and mineral supplementation is usually recommended because the surgery reduces nutrient absorption.

7. How much weight can I lose after OAGB?

Weight loss varies from person to person, but many patients experience significant long-term weight reduction when they follow dietary and lifestyle recommendations.

8. When can I return to work?

Most patients can resume light work within two to three weeks, depending on their recovery and job requirements.

9. Can OAGB improve diabetes?

Many patients experience significant improvement or remission of Type 2 diabetes after OAGB, although individual outcomes vary.

10. How do I book a consultation?

You can schedule an appointment with Dr. Sanjay Verma in Vasant Kunj for a detailed bariatric evaluation and a personalized treatment plan.
