FAQ

BMI of 43 — is it good or bad?

BMI 43 for Males and Females means Morbid Obesity/Class III

Is BMI of 43 dangerous?

BMI of 43 falls into the "Morbid Obesity/Class III" category. A BMI of 25 or more may indicate excess body weight. Consult a healthcare professional for personalized advice.

What weight gives a BMI of 43?

BMI is weight divided by height in metres squared, so it names a weight only once the height is fixed: at 170 cm (5 ft 7 in) a BMI of 43 means about 274 lb (124.3 kg). A taller person reaches the same BMI at a proportionally higher weight.

Does a BMI of 43 mean the same for men and women?

Yes — the WHO adult scale has no separate cut-offs by sex, so a BMI of 43 reads as "Morbid Obesity/Class III" for both. Age is what changes it: the adult table starts at 18, while children and teenagers aged 5–19 are compared with age- and sex-specific reference values instead.
