High blood sugar is called hyperglycemia. It means glucose in the blood is higher than normal, which can happen when there isn’t enough insulin or when the body's cells don’t respond properly to insulin. The other terms describe different problems: hypoglycemia is low blood sugar, hypertension is high blood pressure, and hyperlipidemia is high fats in the blood. So hyperglycemia specifically refers to elevated glucose levels, a key concern in conditions like diabetes that requires monitoring and management to prevent complications.
