Shedding Weight, Gaining Health: A Guide to Weight Loss Surgery in Singapore
4 min read

Obesity is a growing concern worldwide, and Singapore is no exception. For individuals struggling with significant weight and its associated health risks, weight loss surgery (WLS) can be a life-changing option. This blog post dives into the world of WLS in Singapore, exploring different types of procedures, eligibility criteria, potential benefits, and resources for finding qualified surgeons.

Understanding Weight Loss Surgery

WLS, also known as bariatric surgery, is a set of surgical procedures performed to modify the digestive system and promote weight loss. While not a magic bullet, WLS can be a powerful tool for individuals with a Body Mass Index (BMI) exceeding 40 or 35 with obesity-related health conditions like diabetes or sleep apnea.

Types of Weight Loss Surgery

There are three main categories of WLS procedures, each with its own mechanism for promoting weight loss:

  • Restrictive Procedures: These surgeries limit the amount of food the stomach can hold, leading to earlier feelings of fullness and reduced calorie intake. Examples include Laparoscopic Adjustable Gastric Band (LAGB) and Sleeve Gastrectomy (SG).
  • Malabsorptive Procedures: These surgeries alter the digestive system to limit nutrient absorption. Roux-en-Y Gastric Bypass (RYGB) is the most common example, where a portion of the stomach is bypassed, causing food to bypass some of the small intestine.
  • Biliopancreatic Diversion with Duodenal Switch (BPD-DS): This combines elements of both restrictive and malabsorptive procedures, resulting in significant weight loss but requiring lifelong vitamin and mineral supplementation due to reduced absorption.

Benefits of Weight Loss Surgery

Beyond just weight loss, WLS can offer a range of potential health benefits, including:

  • Improved control of type 2 diabetes
  • Reduced risk of heart disease, stroke, and certain cancers
  • Improved sleep quality
  • Increased mobility and pain relief from weight-related joint stress
  • Improved mental health and self-esteem

Eligibility for Weight Loss Surgery in Singapore

WLS is not for everyone. Singapore's Ministry of Health has established specific criteria to ensure patient safety and suitability. Generally, you may be considered for WLS if you meet the following:

  • BMI exceeding 40 or 35 with obesity-related health problems.
  • Have documented attempts at weight loss through diet and exercise for at least six months.
  • Possess a good understanding of the risks and benefits of WLS and are committed to lifestyle changes post-surgery.

Finding a Qualified Weight Loss Surgeon in Singapore

Singapore boasts a network of skilled and experienced weight loss surgeons. Here are some resources to help you find the right fit:

  • Hospital Websites: Major hospitals in Singapore list their bariatric surgery programs on their websites, often with details about the surgeons' qualifications and experience.
  • Singapore Medical Council (SMC) Website: The SMC maintains a searchable online directory of all registered doctors in Singapore. You can filter your search by specialty (General Surgery) and location.
  • Professional Associations: The Singapore Surgical Society website may list member surgeons specializing in weight loss surgery.
  • Patient Reviews: Online platforms and forums can offer patient experiences and reviews of bariatric surgeons. While not the sole deciding factor, they can provide insights into a surgeon's communication style and bedside manner.

Beyond Surgery: Long-Term Success with WLS

WLS is a powerful tool, but it's not the finish line. Long-term success requires commitment to lifestyle changes, including a healthy diet, regular exercise, and ongoing support.


Weight loss surgery can be a life-altering option for individuals struggling with obesity and its associated health problems. By understanding the types of procedures, eligibility criteria, potential benefits, and available resources for finding qualified surgeons in Singapore, you can make informed decisions about your weight loss journey. Remember, WLS is a tool, and achieving lasting results requires a dedicated and holistic approach to long-term health.
