What is Bariatric Surgery?

Bariatric surgery is a group of medical procedures designed to help people with severe obesity achieve significant and sustainable weight loss. Unlike temporary diets, bariatric surgery works by: - Reducing stomach size → You feel full after eating smaller meals. - Altering hormones → Hunger hormones like ghrelin decrease, reducing appetite. - Improving metabolism → Many obesity-related conditions like diabetes and hypertension improve dramatically. the most commonly performed bariatric procedure is Laparoscopic Sleeve Gastrectomy, where around 70–80% of the stomach is removed. The result is a smaller, banana-shaped stomach that holds less food and reduces hunger.

Who is a suitable candidate for Bariatric Surgery?

You may qualify for bariatric surgery if: - Your Body Mass Index (BMI) is above 40 (severe obesity). - Your BMI is above 35 and you also suffer from conditions such as: - Type 2 Diabetes - High Blood Pressure - Polycystic Ovarian Syndrome (PCOS) - Obstructive Sleep Apnea (OSA) - Osteoarthritis of knees/hips - You have tried non-surgical methods like diet, exercise, and medications without lasting success. - You are mentally prepared for long-term lifestyle changes and follow-up care. Our expert surgeon carefully evaluates every patient with a detailed preoperative assessment, including blood tests, heart/lung evaluation, and psychological readiness before recommending surgery.

What is Sleeve Gastrectomy and how does it work?

Sleeve Gastrectomy is currently the most popular bariatric procedure worldwide. During this surgery: - About 70–80% of the stomach is removed. - The remaining stomach looks like a narrow “sleeve” or tube. - Patients feel full quickly and consume much smaller portions. - Levels of ghrelin (hunger hormone) drop, reducing cravings. The surgery not only leads to weight loss but also has a metabolic effect, improving conditions like diabetes and high cholesterol even before major weight loss occurs.

How long does the surgery take and how many days will I need to stay in the hospital?

• Duration of surgery: 1–2 hours (on average). • Hospital stay: Most patients are discharged within 2–3 days after surgery. • Patients start walking the same evening or the next day. This quick recovery is possible because the surgery is done laparoscopically through small incisions, with minimal pain and faster healing.

Yes. Bariatric surgery is considered safe when performed by experienced surgeons using modern laparoscopic (keyhole) techniques. In fact, the risk level is comparable to common operations such as gallbladder or hernia surgery.

In our practice, with over 25 years of surgical experience and more than 400 bariatric surgeries, we have consistently achieved excellent safety outcomes. Every surgery is conducted in advanced operation theatres with strict safety protocols.

No major scars. The surgery uses keyhole incisions (0.5–1 cm each). These tiny cuts usually heal well and fade over time, leaving only small, faint marks that are barely noticeable.
