WH Result Take Care (possibly underweight)

What does this mean for you?

Take care:

A Waist-to-Height ratio (WtHR) of less than 0.4 is below the ‘healthy range’ and indicates you may be underweight. While you might not face the same health risks as people living with obesity, being underweight can still come with other health considerations. Consult your doctor or healthcare professional for an evaluation and further support.
