BMI Calculator – Are You Eligible for Weight Loss Surgery? Check your Body Mass Index & understand your weight-related health risks
Your Body Mass Index (BMI) is a quick and effective way to determine whether your weight is healthy for your height. It’s commonly used by doctors to assess eligibility for weight loss surgery and to evaluate risks related to obesity and metabolic disease.
BMI is not a perfect tool, as body types differ, but it provides a reliable indicator of whether your current weight may be affecting your health. (If you're of South or Southeast Asian racial background, add 2.5 points to your actual BMI in order to determine your health risk)

Example:
If you're 165 cm tall, a healthy weight is between 54 kg and 68 kg.
If you weigh over 81 kg, your BMI is above 30, placing you in the obesity range.

BMI Over 30 – You are eligible for Weight Loss Surgery
If your BMI is 30 or higher, you fall into the obese category, and your risk of conditions such as type 2 diabetes, reflux, high blood pressure, sleep apnoea and joint pain increases significantly.
- Bariatric surgery may be an appropriate treatment option, especially if past weight loss attempts haven’t resulted in long-term success.
- Surgery works by reducing hunger, providing portion control, improving gut metabolism, and resetting your body’s weight set-point, making sustainable weight loss more achievable.
