Low blood sugar is called hypoglycemia. A blood sugar level below 70 mg/dL (3.9 mmol/L) is low and can harm you. A blood sugar level below 54 mg/dL (3.0 mmol/L) is a cause for immediate action. You are at risk for low blood sugar if you have diabetes and are taking any of the following diabetes medicines: Insulin.

Hyperglycemia and hypoglycemia in type 2 diabetes. If someone has diabetes that isn't treated properly, they have too much sugar in their blood (hyperglycemia). Too little sugar in the bloodstream (hypoglycemia) is usually a side effect of treatment with blood-sugar-lowering medication.

Hypoglycemia is a condition in which your blood sugar (glucose) level is lower than normal. Glucose is your body's main energy source. Hypoglycemia is often related to diabetes treatment. But other drugs and a variety of conditions — many rare — can cause low blood sugar in people who don't have diabetes.

With type 1 diabetes, beta cells produce little or no insulin. Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. This buildup of glucose in the blood is called hyperglycemia.

Normal blood sugar levels are less than 100 mg/dL after not eating (fasting) for at least eight hours. And they're less than 140 mg/dL two hours after eating. During the day, levels tend to be at their lowest just before meals.

That's the interstitial fluid (ISF), a thin layer of fluid that surrounds the cells of the tissues below your skin, not from your blood. There is a 5 to 10 minute delay in ISF glucose response to changes in blood glucose. Glucose readings on ISF have been proven to reliably reflect glucose levels2.

A recent large study showed that the most common causes of hypoglycemia were smaller than usual food intake, delay in eating, or skipping a meal. Common symptoms of low blood sugar are: Feeling dizzy, shaky, or lightheaded.
