WHO Western cutoffs differ — Asian thresholds are lower
Category BMI Range Recommendation
Normal 18.5 – 22.9 Maintain lifestyle
Overweight 23.0 – 27.4 Diet & exercise
Obese Class I 27.5 – 32.4 Medical management
Obese Class II 32.5 – 37.4 Consider surgery*
Obese Class III ≥ 37.5 Surgery recommended

Why Asian BMI Cutoffs?

Standard WHO BMI cutoffs were developed based on Western populations. Research has shown that Asians — including Malaysians — develop obesity-related health problems such as Type 2 diabetes, high blood pressure, and cardiovascular disease at lower BMI levels than their Western counterparts. Asian-specific cutoffs better reflect the actual health risk for our population.

Am I a Candidate for Bariatric Surgery?

Bariatric surgery is considered for patients who meet the following criteria under Asian BMI guidelines:

  • BMI ≥ 37.5 — surgery generally recommended
  • BMI 32.5–37.4 with obesity-related conditions (diabetes, hypertension, sleep apnoea)
  • Failed previous non-surgical weight loss attempts
  • Committed to long-term lifestyle changes after surgery
