How to Share Health Data with Your Doctor

If you track your health with a phone or wearable device — blood pressure readings, blood glucose levels, heart rate, activity, or sleep — sharing this data with your doctor gives them valuable information they cannot get from a single office visit. Trends over weeks and months can reveal patterns that help with diagnosis and treatment decisions.

Apple Health (iPhone) can share data directly with your healthcare provider if they support it. Open Health → Sharing → "Share with a Healthcare Provider." If your provider uses a compatible system (many MyChart providers support this), your data flows automatically. Otherwise, you can export specific data: Health → Browse → select a category → "Show All Data" → export icon → share via email or AirDrop.

For blood pressure or blood glucose readings: if you log readings in a health app, bring your phone to your appointment and show the history to your doctor. Most doctors find this very helpful. You can also take screenshots of your data trends and print them out.

Fitbit and Samsung Health allow you to export data as CSV files through the app or website, which you can email to your doctor. Fitbit: go to fitbit.com → Settings → Data Export. Samsung Health: Menu → Settings → Download Personal Data.

When sharing, focus on what is relevant to your current health concerns. If you are tracking blood pressure, show the blood pressure trends. If you are working on fitness, show step counts and active minutes. Your doctor does not need to see every piece of data.

Before your appointment, prepare a one-page summary: your recent averages, any concerning readings, and questions about the data. This makes the most of your limited appointment time.
