Hypoglycemia: Understanding Low Blood Sugar - Symptoms & Causes

The lack of sugar in the blood is called hypoglycemia. It occurs when the body has less than the normal amount of sugar (glucose) in the bloodstream. Glucose is the body's main source of energy, so low blood sugar can cause various symptoms, including weakness, dizziness, hunger, sweating, and confusion. In severe cases, hypoglycemia can lead to seizures, coma, or even death.
