Hyperglycemia is defined as an abnormally high level of glucose in the blood. It typically occurs when the body either does not produce enough insulin or cannot effectively use insulin, which is essential for glucose to enter cells. This condition is commonly associated with diabetes mellitus but can also stem from other factors such as stress or illness. Recognizing hyperglycemia is crucial, as prolonged high blood sugar can lead to serious health complications, including diabetic ketoacidosis or hyperglycemic hyperosmolar state if not managed properly.

In contrast, low blood sugar levels indicate hypoglycemia, while normal blood sugar levels reflect a healthy metabolic state. Dehydration is a separate condition that can occur as a result of hyperglycemia due to increased urination, but it does not define the state of blood glucose levels specifically. Thus, identifying high blood sugar levels as the indication of hyperglycemia is essential for managing and understanding potential health risks.
