Hi Kieran Durrie,

Thank you for posting! From your screenshot, we see that your Health app is using an unexpectedly high amount of data. We certainly understand your concern with that, and we're happy to help as much as possible.

To double-check, have you been receiving any notifications about your storage?

Did you already update your device to iOS 14, or are you using a version of iOS 13?

Also, are you using iCloud to sync your Health data?
