Medical terminology can be a bit confusing, even when the item in question is something very basic, like blood sugar. You’ve probably heard someone in your life talk about their blood sugar — also known as blood glucose — before. In truth, blood sugar levels affect everyone, not just those with diabetes. Temporary rises and falls in blood sugar can cause a host of problems, such as fatigue, weakness, nausea, vomiting, dizziness and headaches. Ongoing issues with blood sugar can lead to serious health conditions.

Learning about normal blood sugar levels is helpful for everyone and absolutely critical for those managing endocrine conditions like diabetes or hypoglycemia. If you’re not sure what “normal” should look like, check out this guide to normal blood sugar levels and diabetes test range numbers.
