Check Your BMI (Body Mass Index)
By WeCovr
A quick and easy way to check on your health
Your Body Mass Index (BMI) is a widely used measure that uses your height and weight to gauge if you are in a healthy weight range. It's a useful starting point for understanding your overall health.
Maintaining a healthy BMI can reduce your risk of developing several health conditions. From an insurance perspective, having a healthy BMI can sometimes lead to more favourable premiums, as it indicates a lower health risk. We believe in empowering you with tools and information to take a proactive approach to your well-being.
