BMI Calculator
Body mass index or BMI is an easy way to assess whether your weight is in the healthy range. It is a simple calculation using your weight and your height. Please use our bmi tracker (insert link) and refer to the guide below for your range.
A healthy range is the ideal for reducing future health risks.
Being underweight (a score below 18.5) can lead to a weakened immune system, fertility issues and osteoporosis.
A higher bmi score (over 25) can lead to health problems including high blood pressure, heart disease, strokes, Type 2 diabetes, osteoarthritis and joint pain.
Your BMI classification sits in the underweight area. You should talk to your GP for support and advice and pay attention to increasing your calorie intake slowly from a balanced diet.
There are various resources on a healthy, balanced diet available - You can find information on the eatwell guide and other resources on our information pages and NHS live well for information on finding the cause of being underweight and tips on gaining weight healthily.
