Which of the following is a common sign of hypoglycemia?

Sweating is indeed a common sign of hypoglycemia. When blood sugar levels drop significantly, the body activates the sympathetic nervous system as a stress response. This results in the release of adrenaline (epinephrine), which can cause symptoms like sweating, tremors, and a feeling of anxiety. Sweating occurs because the body is attempting to regulate its temperature and respond to the stress induced by the low blood sugar level.

Other symptoms associated with hypoglycemia can include dizziness, nausea, and headaches, but sweating is particularly characteristic and often one of the first signs that an individual's blood sugar is falling. Recognizing these symptoms is crucial for prompt intervention, as hypoglycemia can lead to more severe complications if not addressed in a timely manner.
