Low blood sugar also known by the name hypoglycemia usually occurs as a result of side effects of the drugs for diabetes.

The normal range of blood sugar is 70 – 100 mg or dL in a person without diabetes. Most people experience the symptoms and effects when their blood sugar levels are below 50 mg or dL.

The symptoms and severity of hypoglycemia, i.e., low blood sugar might vary from one individual to another.

A blood test might diagnose low blood sugar. Also, symptoms resolve when the blood sugar levels go back to their normal range. The medical term for low blood sugar is low blood glucose.
