What is the condition characterized by rapid breathing often linked to anxiety?

The condition characterized by rapid breathing often linked to anxiety is hyperventilation. When a person experiences anxiety, their body may react by increasing the rate and depth of breathing, leading to hyperventilation. This rapid breathing can cause a decrease in carbon dioxide levels in the blood, which can result in symptoms such as lightheadedness, tingling in the extremities, and even a sense of panic, which further exacerbates the anxiety.

In the context of the other choices, while hypoglycemia involves low blood sugar and can lead to symptoms like confusion and shakiness, it is not specifically associated with rapid breathing. Hypotension refers to low blood pressure, which can cause dizziness but does not typically manifest through rapid breathing. Bradycardia, or a slow heart rate, is another condition that does not directly encompass symptoms of rapid breathing linked to anxiety. Therefore, hyperventilation is clearly defined by its association with rapid breathing and anxiety, making it the correct answer.
