What is hyperventilation syndrome characterized by?

Hyperventilation syndrome is primarily characterized by rapid breathing and lightheadedness. When a person hyperventilates, they breathe at an abnormally fast rate, which leads to a decrease in carbon dioxide levels in the blood, a state known as respiratory alkalosis. This condition can result in various symptoms, including dizziness and lightheadedness, as the brain and body receive an inadequate balance of oxygen and carbon dioxide.

Additionally, rapid breathing can cause a sensation of breathlessness, even though the person is inhaling more air than usual. This syndrome is often associated with anxiety or panic, but the hallmark signs are specifically the rapid and often shallow breathing pattern coupled with feelings of lightheadedness. Understanding these symptoms helps in recognizing hyperventilation syndrome and differentiating it from other respiratory or cardiovascular conditions.
