Gastric Bypass

Gastric bypass surgery is a well-established bariatric procedure that involves reducing the size of the stomach and rerouting part of the small intestine. This limits food intake and decreases calorie absorption.

The most common technique is the Roux-en-Y gastric bypass, where a small stomach pouch is created and connected directly to a section of the small intestine. Food bypasses most of the stomach and part of the intestine, supporting weight loss and improving metabolic function.

Mini gastric bypass (MGB), also known as one-anastomosis gastric bypass, is a modified version of traditional bypass surgery. It involves creating a small stomach pouch and connecting it to the intestine with a single connection rather than two.

This technique may reduce surgical time and recovery while offering similar weight-loss outcomes. Mini gastric bypass surgery in Dubai is selected based on clinical evaluation and patient suitability.

Gastric bypass surgery is performed laparoscopically under general anesthesia.

Procedure steps:

• Anesthesia: General anesthesia is administered for comfort and safety.

• Stomach pouch creation: A small pouch is created from the upper portion of the stomach.

• Intestinal rerouting: A section of the small intestine is connected to the pouch.

• Reduced absorption: Food bypasses part of the digestive tract, reducing calorie intake.

• Hormonal changes: The procedure alters gut hormones that influence hunger and metabolism.

The surgery typically takes 2–3 hours, and most patients stay in the hospital for 1–2 days.

Eligibility for gastric bypass surgery is determined through medical assessment. Candidates may include individuals who:

• Have a body mass index (BMI) of 35 or higher

• Have a BMI of 30–34.9 with obesity-related conditions such as diabetes or hypertension

• Have attempted supervised weight-loss programs without long-term success

• Are medically and psychologically prepared for lifestyle changes after surgery

A comprehensive evaluation is required to determine whether Roux-en-Y or mini gastric bypass is appropriate.

Gastric bypass surgery may help patients achieve:

• Sustained reduction in excess body weight

• Improved management of obesity-related conditions (diabetes, hypertension, sleep apnea)

• Reduced appetite and improved portion control

• Improved physical mobility

• Long-term metabolic health support

• Structured weight management with medical follow-up

Results vary and depend on adherence to dietary, lifestyle, and medical guidance.

The choice of procedure is determined based on clinical factors, BMI, and medical history.

Recovery after gastric bypass surgery typically includes:

• Hospital stay: 1–2 days

• Diet progression: Liquid → pureed → soft → solid foods over several weeks

• Activity: Light activity in 7–10 days; gradual return to full activity in 4–6 weeks

• Follow-up: Regular visits with the bariatric team for nutritional monitoring and progress assessment

Long-term follow-up and lifestyle adherence are essential for sustained outcomes.

Gastric bypass surgery is generally safe when performed by qualified surgeons. Possible risks include:

• Nutrient deficiencies (iron, vitamin B12, calcium)

• Dumping syndrome

• Temporary nausea or reflux

• Leakage at surgical connections (rare)

• Infection or bleeding (rare)

All risks are discussed during consultation, and preventive measures are implemented.

The cost of gastric bypass surgery varies based on:

• Type of procedure (standard or mini bypass)

• Surgeon’s experience

• Hospital and facility fees

• Preoperative investigations

• Postoperative care and nutritional support

A personalized cost estimate is provided after clinical evaluation.
