Gaining weight can be difficult for some people. With a few changes, you can gradually reach a healthy weight.
Being underweight could mean you're missing out on vitamins and minerals.
This could lead to health problems such as a weak immune system and bone fractures.
Non-urgent advice: Speak to a GP if:
- you've lost weight suddenly
- you’ve lost weight without changing your diet or exercise routine
- you use the control of food to cope with feelings and other situations
This could be a sign of an underlying health condition.

Find out if you're underweight
Body mass index (BMI) is a measurement that can show you if you're a healthy weight.
You'll need your height and weight to calculate your BMI.
