how high is too high a blood sugar level?

It depends on the time of day, how long since you've eaten, what you ate, etc. It also depends on whether or not you are diabetic. For non-diabetics, the parameters are different than for diabetics who are on insulin or oral meds. Why are you asking...are you concerned about yourself or someone close to you?

Can you give us some numbers, and when they were taken (fasting, after eating, etc.)?

Keps,

Yes, heed Ruth's message. Know that you will receive a variety of responses back, and most do NOT represent the ADA's recommendations.

Pass along more information for us to discuss.

Wish you well!
