Can blood sugar rise even if you haven't eaten all day?

Yes. The liver continues releasing and producing glucose during fasting. Insulin deficiency, insulin resistance, stress, or illness can cause levels to rise.

Why does my blood sugar go up between meals?

Your liver naturally supplies glucose between meals. If glucose enters the bloodstream faster than your body can use or store it, your reading may increase.

Can stress raise blood sugar without food?

Yes. Stress hormones can increase liver glucose production and temporarily reduce insulin effectiveness.

Should I skip meals if my blood sugar is high?

Not automatically. Skipping meals is not a reliable treatment for high blood sugar and can cause problems for people taking insulin or certain diabetes medications. Follow your individualized care plan.
