What is a common sign of hyperglycemia in patients with diabetes?

Excessive hunger is a common sign of hyperglycemia in patients with diabetes. When blood glucose levels are elevated, the body is unable to utilize glucose effectively, which can lead to feelings of increased hunger as the cells are signaling for more energy. This is part of the metabolic response to high blood sugar levels where the body is trying to compensate for the lack of glucose uptake into the cells.

In contrast, other symptoms related to hyperglycemia can include increased thirst, frequent urination, and fatigue, but these are not options here. Understanding this symptom is crucial for EMTs and healthcare providers, as recognizing excessive hunger along with other signs can help differentiate hyperglycemia from hypoglycemia or other diabetic issues during assessment and treatment.
