Bariatric Surgery

Bariatric surgery refers to a variety of surgical procedures designed to help people with obesity lose weight by making changes to their digestive system. These surgeries alter the stomach and/or intestines to limit food intake, reduce nutrient absorption, or change the way the body digests food, leading to significant and long-term weight loss. It is often recommended for individuals with a Body Mass Index (BMI) over 40 or over 35 with related health issues like diabetes, hypertension, or sleep apnea.

Types of Bariatric Surgery

1. Gastric Bypass (Roux-en-Y Gastric Bypass):
Procedure: A small pouch is created from the stomach and connected directly to the small intestine.
Effect: Reduces food intake and nutrient absorption.

2. Sleeve Gastrectomy:
Procedure: About 75–80% of the stomach is removed, leaving a banana-shaped tube.
Effect: Reduces food intake and alters hunger hormones.

3. Mini Gastric Bypass Surgery (MGB):
MGB, or Single Anastomosis Gastric Bypass, is a simpler alternative to traditional bypass surgery.

1. Procedure:
A small stomach pouch is stapled vertically. A loop of intestine (150–200 cm from stomach) is connected to the pouch, bypassing part of the intestine.

2. Mechanism of Weight Loss:
Restriction: Limits food intake.
Malabsorption: Reduces nutrient and calorie absorption.

3. Advantages:
Simpler operation, shorter time, fewer complications, comparable results, possibly reversible.

4. Potential Risks:
Includes leaks, infection, nutrient deficiencies (B12, iron, calcium), bile reflux.

5. Long-Term Effects:
Patients may lose 50–70% of excess weight in 1–2 years. Requires lifelong diet/vitamins/follow-ups.

Advantages of Bariatric Surgery

1. Significant and Long-term Weight Loss:
Improves quality of life and overall health.

2. Improvement in Obesity-related Conditions:
Diabetes, hypertension, sleep apnea, and heart disease risks are significantly reduced.

3. Better Mobility and Physical Activity:
Improved movement, reduced joint pain, increased energy.

4. Improved Mental Health:
Better self-esteem, less depression.

5. Increased Longevity:
May increase life expectancy.

6. Lower Risk of Certain Cancers:
Reduced risk of colon, breast, and uterine cancers.

Please Note:
Bariatric surgery is not a quick fix. Requires long-term lifestyle changes and medical follow-up.
