## Important information

This calculator is for general educational purposes only. It gives an estimate and is not medical advice, a diagnosis, or a treatment recommendation. It does not determine whether you qualify for any medication or treatment, and using it does not create a patient-provider relationship with Living+ Rx or any provider.

BMI is a screening measure. It does not directly measure body fat or health, and it can be misleading for some people, including athletes, people with a lot of muscle, and older adults. It is not intended for anyone under 20 or anyone who is pregnant.

Talk with a licensed health care professional before changing your diet, exercise, or medication. If you think you are having a medical emergency, call 911.
