Bariatric surgery includes procedures like gastric sleeve and gastric bypass that modify the stomach or intestines to treat severe obesity. It helps patients lose significant weight when diet and medication have failed.
Beyond weight loss, it improves obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea. Surgery is recommended for BMI ≥37.5, or ≥32.5 with comorbidities.
Start your weight loss transformation with Malaysia’s trusted bariatric surgeon, Dr. Navin Mann. Specializing in gastric sleeve, gastric bypass, and metabolic surgery, we combine advanced safety with lifelong support for results that last.
Bariatric surgery is a medical treatment, not a cosmetic procedure. It’s considered when your health is at risk from severe obesity and you haven’t maintained weight loss through structured diet, exercise, or anti-obesity medications.
It helps in 3 ways:
If you have these conditions, bariatric surgery may do more than help you lose weight:
Procedure | What’s Done | Avg. Cost Malaysia | 5-Year Excess Weight Loss | Hospital Stay |
|---|---|---|---|---|
Gastric Sleeve Sleeve Gastrectomy | Removes 80% of stomach along greater curve | RM 28,000 – RM 38,000 | 50–60% | 2–3 days |
Gastric Bypass Roux-en-Y | Small stomach pouch + bypass of duodenum | RM 35,000 – RM 50,000 | 60–70% | 2–4 days |
Duodenal Switch BPD/DS | Sleeve + major intestinal bypass | RM 45,000 – RM 55,000 | 70–80% | 3–5 days |
Gastric Band Lap Band | Adjustable silicone band on upper stomach | RM 25,000 – RM 32,000 | 40–50% | 1–2 days |
Choose based on your health profile, not just weight loss numbers.
Gastric Sleeve fits if you:
Gastric Bypass fits if you:
Key risk trade-off: Bypass has higher early risk of internal hernia and ulcers. Sleeve has higher risk of new or worsened acid reflux in 15–20% of patients.
Duodenal Switch: Gives the most weight loss and diabetes control. Also carries the highest risk of protein malnutrition, diarrhea, and deficiencies in vitamins A, D, E, K. You must commit to lifelong blood tests and supplements. Only offered by a small number of experienced teams.
Lap Band: Lowest surgical risk and reversible. But 40–50% need removal or conversion within 10 years due to slippage, erosion, or poor weight loss. Most surgeons now recommend sleeve or bypass as first-line.
Your surgeon will match procedure to your goals and risks. General guidance:

Scenario | Out-of-Pocket Cost | Key Notes |

Within 30 days: Leak 1–2%, bleeding 1%, blood clots 0.3–0.5%, wound infection. Risk of death <0.3% at high-volume centers — similar to gallbladder removal.

Measured as % of excess weight lost. “Excess weight” = current weight minus ideal weight.
Weight regain: 20–25% of patients regain ≥15% of lost weight by 10 years. Regain is tied to snacking, liquid calories, alcohol, and missing follow-up.

Your bariatric team will require:
You’ll be admitted the morning of surgery. All procedures are done laparoscopically through 4–5 small cuts. Surgery lasts 60–120 minutes. You’ll be asked to walk a few hours after. Clear liquids start the same day.
You’ll advance in stages to let your stomach heal:
Next step: Book a consultation with a bariatric team for a personalized assessment. Bring your medical records, medication list, and past weight loss attempts.
