Bariatric and Metabolic Surgery
A Definitive, Evidence-Based Solution for Obesity and Metabolic Disorders
Obesity is a chronic medical condition characterised by excessive fat accumulation that negatively impacts overall health. When lifestyle changes and medical therapy are insufficient, bariatric and metabolic surgery offers a scientifically proven, long-term solution for obesity and associated metabolic diseases such as Type 2 Diabetes, hypertension, dyslipidemia, sleep apnoea, and more.
Who Is Eligible for Bariatric Surgery?
According to current international and Indian guidelines, surgery is recommended for individuals with:
- BMI ≥ 37.5 kg/m², or
- BMI ≥ 32 kg/m² with obesity-related complications such as diabetes, fatty liver, hypertension, or sleep apnoea.
How Bariatric Surgery Works
Bariatric procedures bring metabolic improvements through three primary mechanisms:
- Restriction: A smaller, reshaped stomach limits food intake.
- Reduced Absorption: Bypassing select intestinal segments reduces calorie absorption.
- Hormonal Regulation: Changes in gut hormones lead to reduced hunger and cravings.
How the Surgery Is Performed
Most procedures are performed using laparoscopic or robotic techniques, which require 5-6 tiny incisions measuring 1 cm or less, ensuring faster recovery and minimal scarring.
Diet & Recovery
- Clear fluids typically begin 12 hours after surgery.
- Diet progression follows a structured protocol.
- Usual hospital stay: 3–5 days.
Common Bariatric Procedures
- Laparoscopic Mini Gastric Bypass (MGB)
Recommended for:
- Morbid obesity
- Metabolic syndrome
- Uncontrolled Type 2 Diabetes
Combines restriction + malabsorption for sustained weight loss.
- Laparoscopic Sleeve Gastrectomy
Ideal for:
- Class I & II obesity
Patients without severe metabolic complications
Primarily a restrictive procedure.
