Laparoscopic Sleeve Gastrectomy (LSG): Life-Changing Surgical Solution for Weight Management
10 March 2026
Obesity is a growing health concern in Malaysia. More than half (53.6%) of Malaysian adults are now overweight or obese according to the Global Obesity Observatory, placing Malaysia among the highest in Southeast Asia.
Beyond excess weight, obesity increases the risk of serious non-communicable health conditions, including type 2 diabetes mellitus, hypertension, cardiovascular disease, obstructive sleep apnoea (OSA), fatty liver disease, certain cancers, and more. While healthy eating, regular physical activity, and medical therapy are essential first-line strategies to managing obesity, they may not always lead to sustained weight loss for some individuals.
In such cases, surgical weight loss options like Laparoscopic Sleeve Gastrectomy (LSG) can be considered as part of a comprehensive obesity management plan.
What Is Laparoscopic Sleeve Gastrectomy (LSG)?
Laparoscopic Sleeve Gastrectomy is a minimally invasive weight loss surgery that removes approximately 75 to 80 percent of the stomach, leaving a smaller, sleeve-shaped stomach. This limits food intake and decreases appetite by lowering levels of hunger hormones.
Performed through small keyhole incisions with camera-guided laparoscopic tools, this bariatric surgery offers several benefits:
- Less pain and scarring
- Shorter hospital stays
- Faster recovery
- Lower complication rates compared with open surgery

Sleeve gastrectomy may also be performed using a robotic-assisted surgery approach, offering greater surgical precision.
Who Is Laparoscopic Sleeve Gastrectomy (LSG) Suitable For?
- Individuals with BMI above 27.5kg/m²
- Individuals with obesity-related comorbidities, such as type 2 diabetes, hypertension, high cholesterol, fatty liver, obstructive sleep apnoea (OSA), back or knee joint pain, and others
- Individuals who have tried lifestyle modifications such as diet, exercise and/or medications without success
