Your BMI is a measurement that is a ratio of your weight and height. It’s a good way to gauge whether your weight is in healthy proportion to your height. In fact, knowing your BMI can help you - and your GP - determine any health risks you may face if it’s outside of the healthy range.
Being overweight can lead to a range of chronic conditions including:
- Type 2 Diabetes
- High blood pressure
- Heart or blood vessel problems
- Cardiovascular disease
- Musculoskeletal problems
Being underweight can result in other health issues like:
- Risk of malnutrition
