What is hyperglycemia?

  1. An abnormally low level of blood sugar

  2. A condition indicating normal blood sugar levels

  3. An abnormally high level of blood sugar

  4. A transient fluctuation in blood sugar

The correct answer is: An abnormally high level of blood sugar

Hyperglycemia refers to an abnormally high level of blood sugar (glucose) in the bloodstream. This condition is often associated with diabetes and can occur when the body either does not produce enough insulin or becomes resistant to the effects of insulin. Insulin is a hormone that helps regulate blood sugar levels by facilitating the uptake of glucose into cells for energy or storage. When blood sugar levels rise above the normal range, it can lead to various symptoms and potential complications, such as increased thirst, frequent urination, fatigue, and blurred vision. Prolonged hyperglycemia can result in more serious health issues, including damage to blood vessels, nerves, and organs. Thus, understanding hyperglycemia is critical for managing diabetes and maintaining overall health.
