Talk to a health professional
- Always ask a qualified health professional about any questions you have about a medical condition, symptoms or treatment.

About our tools
Our calculators and charts give general results based on published guidelines. They can't take your own health, history or medicines into account, and they don't diagnose any condition. A result in a "healthy" or "normal" range doesn't mean you have no health problems, and a result outside it doesn't mean you do. Talk to a health professional about your results.
Accuracy
We work to keep our information accurate and up to date and link to the official sources we use (see our editorial policy), but health guidance changes and we can't promise that every page is complete or current. Guidance can also differ between countries.
Links to other websites
We link to official health websites and other sources for more information. We aren't responsible for the content of other websites.
Mental health crisis
If you're thinking about harming yourself, get help now. In the U.S., call or text 988 (the 988 Suicide & Crisis Lifeline) or chat at 988lifeline.org. Elsewhere, call your local emergency number.
