What is a sign of hyperglycemia?

• A. Cold, clammy skin
• B. Confusion
• C. Increased confusion; sluggish mood
• D. Shaking or trembling

Answer: (B)

Confusion is an important sign of hyperglycemia, which refers to elevated levels of glucose in the blood. When blood sugar levels are high, the body can struggle to function properly, affecting cognitive processes and leading to symptoms such as confusion and altered mental status. This disruption occurs because the brain relies on glucose for energy, and excessive glucose can impair its normal function. Recognizing confusion as a symptom is crucial for timely intervention, particularly for individuals with diabetes, where hyperglycemia can lead to more severe complications if not addressed promptly.

Other symptoms associated with hyperglycemia may include frequent urination, increased thirst, and fatigue, but confusion stands out as a more urgent indicator that requires immediate attention.
