Hyperventilation can lead to which serious condition?

Hyperventilation leads to a decrease in carbon dioxide levels in the blood, which can result in respiratory alkalosis. This condition causes various physiological responses, including the constriction of blood vessels that supply the brain. As a result, the brain may not receive adequate blood flow, leading to symptoms like lightheadedness and, in severe cases, loss of consciousness. Understanding this mechanism highlights the importance of recognizing hyperventilation not just as a symptom of anxiety or stress, but as a condition that can have serious consequences if not addressed promptly.
