The World Health Organisation (WHO) defines obesity based on Body Mass Index (BMI). The definition of obesity among Singaporeans and Caucasians is BMI =27.5 and BMI =30 respectively.
BMI | Category | Health Risk | Suggested Treatment |
---|---|---|---|
23 to 27.4 | Overweight | Moderate | Diet and Exercise |
27.4 to 32.4 | Obese | High | |
32.5 to 37.4 | Severely Obese | Very High | Consider obesity surgery |
37.5 and above | Morbidly Obese | Very High |
* BMI values for Asian population according to MOH guideline NIH Concensus Conference.

Adult with BMI more than 27.5 could be classfied as obese
There are many causes that may contribute to weight gain and to develop obesity. Hence, only a multidisciplinary approach can identify the different factors and engage a programme that leads to necessary reduction in weight.
Surgery has proven to be an effective treatment for patients who are morbidly or severely obese for the last 4 decades. It is in fact backed up by a recent study of more than 22,000 patients that patients could expect to lose more than 60%* of their excess weight after bariatric surgery. Another study showed that following surgery, up to 80%* of patients experienced complete resolution or improvement of their co-morbid conditions, such as diabetes, hypertension and sleep apnoea.
In the last 10 years, with the "keyhole" or minimally invasive surgery, bariatric surgery has become much less invasive than the conventional surgery. Bariatric Surgery usually involves a modification of the digestive tract with the aim of reducing the size of gastric reservoir with or without reducing the ability of the gut to absorb food.

Prior to surgery, each patient will be assessed by our multidisciplinary team. Here, it is also emphasised that lifestyle changes such as healthy eating and regular exercise are essential to sustain weight loss after surgery.
