What is the state of having low levels of blood sugar?

Low levels of blood sugar are referred to as hypoglycemia. This condition occurs when the glucose in the bloodstream drops below normal levels, resulting in symptoms such as shakiness, confusion, sweating, and in severe cases, loss of consciousness. Hypoglycemia can be caused by various factors, including prolonged fasting, excessive physical activity, or the overconsumption of insulin or certain medications.

In contrast, hyperglycemia refers to high blood sugar levels, which can occur in conditions such as diabetes. Normal glycemia indicates levels of blood sugar that fall within the healthy range, while insulin resistance describes a condition where the body's cells do not respond well to insulin, leading to issues with blood sugar management. Therefore, hypoglycemia specifically identifies the state of having low blood sugar levels, making it the correct choice in this context.
