Which sign or symptom is associated with hypoglycemia?

• A. Tachycardia
• B. Photophobia
• C. Cough
• D. Memory loss

Answer: (A)

The presence of tachycardia is indeed associated with hypoglycemia, as it is part of the body’s physiological response to low blood glucose levels. When blood sugar drops, the body releases stress hormones, such as adrenaline (epinephrine), which activate the sympathetic nervous system. This heightened state can lead to an increase in heart rate—resulting in tachycardia—as the body attempts to restore normal glucose levels by mobilizing glucose from stores or increasing insulin release.

Recognizing the signs and symptoms of hypoglycemia, such as tachycardia, is vital for early detection and treatment to prevent severe complications, such as loss of consciousness or seizures. Other symptoms often accompanying hypoglycemia may include sweating, trembling, irritability, and confusion, further illustrating the body's stress response to insufficient glucose availability.
