What is one of the main signs of hyperglycemia?

One of the main signs of hyperglycemia, which is a condition characterized by elevated blood glucose levels, is extreme thirst. This occurs because high blood sugar leads to increased urination, which in turn can cause dehydration. The body attempts to compensate for this loss of fluids by triggering the sensation of thirst, prompting the individual to drink more water to rehydrate. Recognizing extreme thirst as a symptom of hyperglycemia is important for timely intervention, as untreated high blood sugar can lead to serious complications, including diabetic ketoacidosis in those with diabetes.

The other symptoms listed, such as cool and clammy skin, shaking or tremors, and pale skin, are typically associated with hypoglycemia (low blood sugar) rather than hyperglycemia. Understanding the distinct signs and symptoms of these two conditions is essential for providing appropriate care and treatment.
