Which of the following is a symptom of hypoglycemia?

Weakness and confusion are classic symptoms of hypoglycemia, which occurs when blood sugar levels drop significantly below normal. When the body does not have enough glucose available for energy, especially for the brain, it can lead to neurological symptoms such as confusion, irritability, dizziness, and weakness. These symptoms arise because glucose is the primary energy source for the brain, and when levels are low, cognitive function and physical strength can be compromised.

While increased appetite, excessive thirst, and high energy levels could be symptoms associated with other conditions, such as hyperglycemia or diabetes, they do not accurately represent the symptoms of hypoglycemia. In contrast, the presence of weakness and confusion directly relates to the lack of glucose available for essential body functions.
