Hello! Lifehacker has detailed material on this topic. The norm of glucose in blood taken on an empty stomach from a vein is from 3.9 to 5.6 mmol / l (70-100 mg / dl).

If the results fall outside these boundaries, we can assume the following:

• From 5.6 to 6.9 mmol / L - prediabetes. Certain processes occur in the body that increase the risk of developing diabetes.
• 7 mmol / L and above - hyperglycemia. Most often, this indicates that you have diabetes.
• Below 3.9 mmol / L - hypoglycemia. An unhealthy condition that can be a sign of a variety of disorders in the body.

An elevated blood sugar level most often indicates a pre-diabetic state or already onset diabetes mellitus. But there may be other causes, such as hyperthyroidism, cancer, pancreatitis, or severe stress.

In any case, unsatisfactory test results should be discussed with a therapist. He will establish the cause, make an accurate diagnosis, and give instructions on how to return the glucose level to normal.

And at the link above, you can find out in more detail about the causes of low blood sugar, as well as about why the deviation of this indicator from the norm is generally dangerous.
