In today’s world, obesity has become one of the most pressing health challenges. Affecting millions globally, it’s not just about weight gain — it’s linked to serious health conditions like diabetes, hypertension, infertility, sleep apnea, heart disease, and more. For many who have tried diets, exercise, and medications without success, bariatric surgery offers hope and results.

But what exactly is bariatric surgery, and who is it for?

What is Bariatric Surgery?

Bariatric surgery refers to a group of procedures designed to help individuals lose weight by altering the digestive system, either by limiting food intake, reducing nutrient absorption, or both. These procedures not only aid in significant weight loss but also improve or resolve obesity-related conditions.

Common Types of Bariatric Surgery

  1. Gastric Sleeve (Sleeve Gastrectomy):
  2. About 80% of the stomach is removed, leaving a smaller “sleeve.” This limits how much you can eat and reduces hunger hormones.
  3. Gastric Bypass (Roux-en-Y):
  4. The stomach is divided, and part of the small intestine is rerouted. It reduces the amount of food you can eat and the calories your body absorbs.
  5. Adjustable Gastric Band (Lap-Band):
  6. A band is placed around the upper part of the stomach to create a small pouch, limiting how much food you can hold.
  7. Biliopancreatic Diversion with Duodenal Switch (BPD/DS):
  8. A more complex procedure that combines both restriction and malabsorption, usually reserved for severe obesity cases.

Who is Bariatric Surgery For?

Bariatric surgery is typically recommended for individuals who:

  • Have a Body Mass Index (BMI) of 40 or higher, or
  • Have a BMI of 35 or higher with serious health problems (like type 2 diabetes or sleep apnea)
  • Have tried and failed with non-surgical weight loss methods
  • Are committed to long-term lifestyle changes and follow-up care

Benefits of Bariatric Surgery

  • Significant and sustained weight loss
  • Reduced risk or resolution of obesity-related diseases
  • Improved mental health and self-esteem
  • Boost in fertility and safer pregnancies.
  • Enhanced mobility and quality of life
  • Reduction or elimination of medications for diabetes, hypertension, etc.

Risks and Considerations

Like all surgeries, bariatric procedures carry risks such as infections, bleeding, nutritional deficiencies, or complications from anaesthesia. That’s why it’s crucial to undergo surgery under the care of skilled bariatric surgeons and in a hospital with comprehensive post-surgery support, including dietary guidance, mental health counselling, and physical activity coaching.

Life After Surgery

Bariatric surgery is not a “quick fix.” It’s a tool, and success depends on long-term lifestyle changes. Patients must commit to:

  • Healthy eating habits
  • Regular exercise
  • Attending follow-up appointments
  • Taking vitamin supplements (as recommended)

With the right support, bariatric surgery can be transformational — physically, emotionally, and medically.
