What is hypoglycemia?

• A. Low blood glucose levels.
• B. High blood glucose levels.
• C. Blood pressure too low.
• D. Kidney function decline.

Answer: (A)

Hypoglycemia means there isn’t enough sugar in the blood to fuel the body's cells. It occurs when blood glucose drops below normal levels, often around 70 mg/dL or lower in many adults. This can happen if you take too much insulin or diabetes medicine, skip meals, or exercise more than usual. Quick recognition of symptoms like shakiness, sweating, hunger, dizziness, or confusion is important, because you should treat it fast with a rapid-acting carbohydrate (such as juice or glucose tablets) and then recheck blood sugar. The other ideas describe different problems: high blood glucose is hyperglycemia, low blood pressure is a circulation issue, and kidney function decline is a kidney problem—not hypoglycemia.
