What level of blood sugar is dangerous?

Normal blood sugar levels are about 70-100 mg/dL. Your blood sugar will naturally fluctuate a bit throughout the day in response to food and other factors. However, it ideally stays within a set range and doesn’t change very much based on what you eat or your level of physical activity.

Blood sugar (glucose) is the main type of sugar in your blood.

You get it from the carbohydrates you consume.
