Bariatric Surgery in Ahmedabad: The Definitive Medical Guide

Obesity is not a lifestyle choice. It is a complex, progressive metabolic disease. Discover how Bariatric Surgery provides the only scientifically proven long-term cure.

1. The Science: Why Diets Fail (Set Point Theory)

Patients often blame themselves for a "lack of willpower." However, the World Health Organization (WHO) classifies obesity as a chronic disease.

The Metabolic Trap: Your body has a "weight thermostat" called the Set Point. When you suffer from morbid obesity, this set point is elevated. According to research from the National Institutes of Health (NIH), if you try to diet, your body triggers a survival response: it lowers your metabolism and spikes Ghrelin (the hunger hormone). This biological defense mechanism is why 95% of people regain lost weight within 2 years.

At Dwarika Hospital, we don't just treat the weight; we treat the underlying metabolic dysfunction. Surgery resets this thermostat, allowing you to lose weight naturally without fighting your own biology.

2. Our Surgical Solutions: Precision & Safety

We utilize advanced 4K Laparoscopic Technology for minimal scarring and faster recovery.

A. Laparoscopic Sleeve Gastrectomy (LSG)

The "Gold Standard" for Volume Eaters. We remove ~80% of the stomach, leaving a banana-shaped tube. This removes the fundus, the part of the stomach that produces Ghrelin. With hunger hormones gone, you feel full after small meals. Read more at Cleveland Clinic.


Time: 45-60 Mins Stay: 2 Days

B. Gastric Bypass (RYGB / MGB)

The "Diabetes Cure". We create a small pouch and bypass a portion of the small intestine. This triggers the Incretin Effect (GLP-1 release), which normalizes blood sugar often before significant weight loss occurs. (Source: Johns Hopkins)


Best for: Uncontrolled Diabetes Best for: Acid Reflux

3. Beyond Weight: Treating the "Deadly Quartet"

Obesity acts as a gateway to Metabolic Syndrome. Dr. Avinash Tank specializes in treating these associated conditions:

Type 2 Diabetes

Surgery can lead to full remission. See American Diabetes Association guidelines.

Hypertension

Weight loss reduces heart strain. American Heart Association confirms reduced stroke risk.

4. Real Stories, Real Results

5. Patient Resources & FAQ

Yes. Modern bariatric surgery is extremely safe. The mortality rate is <0.1%, which is safer than hip replacement surgery. The risk of not treating morbid obesity (heart attack, stroke) is statistically much higher than the risk of surgery.
Skin elasticity depends on age and genetics. We emphasize protein intake and hydration to minimize this. If loose skin persists after 18 months, body contouring can be discussed.
Yes. As per IRDAI Guidelines 2019, Bariatric Surgery is covered if:
  • BMI > 40
  • BMI > 35 with comorbidities (Heart disease, Sleep Apnea, etc.)
Our TPA desk assists with all cashless claims.
Costs vary based on the procedure (Sleeve vs Bypass) and room type. At Dwarika Hospital, we offer transparent packages starting from approx ₹2.5 Lakhs (subject to evaluation).
