Gastric bypass surgery is a type of weight loss surgery that helps individuals with severe obesity lose weight by altering their digestive system. It reduces the size of the stomach and changes how food is absorbed leading to significant weight loss. One of the most common types is Roux-en-Y gastric bypass (RYGB) which helps patients improve their overall health and quality of life.

Doctors may recommend gastric bypass surgery for individuals who:

Have a BMI (Body Mass Index) of 40 or higher (severe obesity).

Have a BMI of 35 or more with obesity-related conditions like diabetes, hypertension or sleep apnea.

Have been unable to lose weight through diet and exercise alone.

Experience serious health risks due to excessive weight.

• Significant Weight Loss: Patients lose a large amount of weight within a year.
• Improves Health Conditions: Helps manage diabetes, heart disease and high blood pressure.
• Long term Results: More effective than a gastric sleeve in maintaining weight loss.
• Enhances Quality of Life: Improves mobility, confidence and overall well-being.
• Reduces Appetite: Changes in gut hormones reduce hunger and improve satiety.

• Medical Evaluation: A thorough check-up to ensure you meet the gastric bypass surgery requirements.
• Dietary Adjustments: Doctors may recommend a gastric bypass diet before surgery.
• Lifestyle Changes: Prepare for a long-term commitment to new eating habits.
• Psychological Counseling: Many doctors recommend therapy to ensure emotional readiness.

• Anesthesia: You are put under general anesthesia.
• Reducing the Stomach Size: The stomach is divided into a small pouch.
• Rerouting the Digestive System: The small intestine is rearranged to connect to the pouch (Roux-en-Y hepaticojejunostomy).
• Bypassing a Portion of the Intestine: This reduces calorie absorption.
• Closure: The procedure is completed laparoscopically (minimally invasive) or through open surgery.

Roux-en-Y gastric bypass surgery has some risks:

• Nutritional Deficiencies: Reduced absorption of vitamins and minerals.
• Dumping Syndrome: Eating high sugar foods may cause nausea and dizziness.
• Surgical Risks: Infection, bleeding or leakage at the surgical site.
• Long term Complications: Some may experience side effects of gastric bypass like ulcers or bowel obstruction even 15 years after gastric bypass.
