Which term describes a high concentration of glucose in the blood?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Polyuria
• D. Pancreatitis

Answer: (A)

Hyperglycemia is the term for high glucose levels in the blood. The prefix “hyper-” means above or excessive, and “glycemia” refers to blood sugar, so together they describe blood sugar that is too high. This contrasts with hypoglycemia, which is low blood glucose. Polyuria describes excessive urination and is a symptom caused by high glucose levels, but it denotes a result rather than the glucose concentration itself. Pancreatitis is inflammation of the pancreas and isn’t related to blood glucose levels. In practice, hyperglycemia is a key feature in diabetes and can lead to symptoms like thirst and fatigue, and in severe cases to urgent medical emergencies.
