What condition occurs when there is too little sugar in the blood?

Hypoglycemia is the condition that occurs when there is too little sugar (glucose) in the blood. This can happen for various reasons, such as excessive insulin production, not eating enough, or prolonged periods of physical activity without food intake. Glucose is essential for providing energy to the body's cells, particularly those in the brain. Symptoms of hypoglycemia can include shakiness, confusion, sweating, irritability, and in severe cases, loss of consciousness or seizures. It is crucial to recognize and treat hypoglycemia promptly to restore normal blood glucose levels and prevent complications.

In contrast, hyperglycemia refers to elevated blood sugar levels, which is typically associated with diabetes. Polyuria and polydipsia are terms relating to excessive urination and excessive thirst, respectively, often linked to conditions like diabetes but not directly describing a state of low blood sugar.
