What is hyperglycemia?

• A. Low blood glucose levels.
• B. High blood glucose levels.
• C. Normal blood glucose levels.
• D. Elevated blood pressure.

Answer: (B)

Hyperglycemia is high blood glucose levels. It happens when there isn’t enough insulin or the body can’t use insulin effectively, which is common in diabetes. When glucose stays elevated, you might notice thirst, frequent urination, fatigue, blurred vision, or headaches. Over time, persistent high glucose can lead to dehydration and other serious complications, so managing it is important. You can diagnose hyperglycemia with lab values such as fasting glucose being 126 mg/dL or higher, random glucose 200 mg/dL or higher with symptoms, or an A1C of 6.5% or higher. The other options describe low glucose, normal glucose, or something unrelated to glucose levels, so they don’t match the meaning of hyperglycemia.
