What are the Normal Blood Sugar Levels?

Q: What are the normal blood sugar levels?



After not eating for at least eight hours, normal blood sugar levels are less than 100 mg/dL and after eating, they’re less than 140 mg/dL two hours.

Blood sugar levels usually stay at their lowest before meals in the daytime. For most people without diabetes, blood sugar levels before meals generally hover between 70 and 80 mg/dL. 60 is normal for some people while for others, 90 is the norm.


Sugar levels exceeding normal are unhealthy. If your sugar levels are higher than normal but not up to the point of full blown diabetes, you have pre-diabetes.


Normally, your body regulates the production of insulin so that you naturally have the amount of insulin you need to help control your sugar levels. But if your body stops producing its own insulin or if it can’t use the insulin produced in an effective way, you need insulin injection or other medications that will increase the amount of insulin your body produces.
