What are the signs and symptoms of hyperglycemia?

The signs and symptoms of hyperglycemia, or high blood sugar, are characterized by increased thirst, frequent urination, blurred vision, and fatigue. When blood glucose levels rise, the body responds by attempting to reduce excess sugar through urination, leading to frequent trips to the bathroom. This can result in dehydration, triggering the sensation of increased thirst. Additionally, hyperglycemia can affect the body's ability to focus and function normally, which is why individuals may experience blurred vision and feelings of fatigue or lethargy. These symptoms are indicative of the body's response to high glucose levels and the physiological stress that arises from trying to manage that condition.

Understanding the specific signs of hyperglycemia is crucial for effective assessment and management in emergency medical contexts.
