Health app lost data after updating to 8.02

I had the same problem and noticed looking at my health data that in the past it was my steps had a little heart next to them for iHealth and now they have a picture of an iPhone. So I clicked on Health Data....then scrolled down to steps....then clicked on share data....and then clicked edit....and I changed my Health source to be first as opposed to my iPhone and it brought them all back into my dashboard.

Its all greyed out and won't let me click to edit it.

I'm not sure if it was due to IOS 8.02, but I just noticed today that all my data is gone. I had a lot of stuff in there already. Everything is gone. As someone else experienced; the app also crashes when I select the "Me" tab in "Health Data".
The only info remaining is the stuff in "Medical ID".
I'm on a 5S and the only app I have linked to it (in "Sources") is "MyFitnessPall".

usually rebooting my device fixes my problem with the health app, now no matter what I do, my dashboard are all empty. I just can't wait for the 8.1 to be release and hope it fix all the issues

I've been having the same problem on my iPhone 6 Plus for the past 2 days. I've been able to restore some after doing a hard boot. I've also went in to each dashboard item and rearranged the order of my share items make my Whitings Pulse primary when applicable and this seemed to help to.

The Health App has issues. All my data comes and goes. It was all gone when I opened the app the first time today. Same as the pat few days. Then for unknown reasons, all the data appeared several minutes later. Now, it's all gone again just a couple of hours after the data returned. Is Apple having an Healthgate issue like the Mapgate? Very unreliable. At least I know the data is still on the iPhone somewhere if it all eventually returns even for just a while.

Agreed @mainmazz. I've been having the same problems. I thought I was able to to resolve the issues. However I get days when data is there and days when it isn't. The data is definitely somewhere, but right now I have no information displayed in my Health App.

You'd think Apple would provide a faster solution for this since they made a big deal about health since their big unveil.

This is very disappointing makes this feature more than useless.

I updated my 5s to 8.1 last night. I had all my blood glucose levels in there to track my diabetes and after the update it was GONE. I put one data point in this morning and shut down my phone for a test and after restarting the phone the data I had just entered was erased again. WORTHLESS POS application.

I had a similar experience - except I didn't reboot - I entered 1 # this morning, and now the Blood Glucose category is entirely missing, not just the data is gone, the ability to track blood glucose is gone!

I lost all health data during first sync after 8.1 installation in 5S. Powered off and on and looks like it is restored.

Earlier it showed dashboard empty. This is not good

I feel y'all but I guess I might be one of the lucky ones without a problem since 8.1 update. I use 5S btw

I don't know others have had their dashboard health app freeze up since the last posting in Sept. but mine just froze up today, Dec. 11. I don't know if there was an update or what, but I"m stuck.
