Obesity is defined by body mass index (BMI) and further evaluated in terms of fat distribution via the waist?hip ratio and total cardiovascular risk factors. BMI is closely related to both percentage body fat and total body fat.One in nine Singaporean adults aged between 18 to 69 years were obese in 2010, and Singapore?s obesity rate is increasing at about 1 per cent per year, a survey revealed today With a suitable diet, anti-obesity drugs may be taken to reduce appetite or decrease fat absorption.
If diet, exercise, and medication are not effective, a gastric balloon may assist with weight loss, or surgery may be performed to reduce stomach volume and/or bowel length, leading to feeling full earlier and a reduced ability to absorb nutrients from food. Excess weight, especially obesity, is a major risk factor for cardiovascular disease, Type 2 diabetes, some musculoskeletal conditions and some cancers.As the level of excess weight increases, so does the risk of developing these conditions. In addition, being overweight can hamper the ability to control or manage chronic disorders.
