oa SA Pharmacist's Assistant - Obesity and overweight : healthy lifestyle
The World Health Organization (WHO) defines obesity and overweight as excessive fat accumulation that presents a health risk. Body mass index (BMI) is used in the classification of patients as underweight, normal weight, overweight or obese (see Table I). BMIs are calculated in the same way, irrespective of age or sex, and should be used as a rough guide only, as they do not always correspond to the same degree of overweight or obesity in different individuals.
