My sugar levels are constantly above the shaded red region - should I be worried?

No. For a few reasons:

1. The red region is the “optimal” range for weight loss and optimal health, it’s not the “normal” range. Everyone is different.
2. Sensors calibrate differently each time, so on one sensor you might be a whole 1.0 higher or lower than previous sensor. Don’t worry about this, we’ll adjust the bars according to your baseline. We care about avoiding spikes, not what your baseline level is.
3. myLevels shows the interstitial or cell glucose level rather than blood glucose level. The two can be different, so the myLevels reading isn’t necessarily a good prediction of your blood glucose levels.

But in any case, myLevels isn’t a medical tool - if you want to know your diabetic status you should see your doctor and schedule a blood test.
