Low carbon dioxide levels in the blood indicate a condition known as hypocapnia. This is often caused by hyperventilation or breathing too rapidly, which makes you eliminate more carbon dioxide than you produce. The common symptoms include light-headedness, tingling sensations, shortness of breath, and confusion. In severe cases, hypocapnia can lead to health problems like hypoxia or shortage of oxygen in the body or more potentially, it can disturb the acid-base balance resulting in alkalosis. It's essential to address the underlying issues leading to hypocapnia, like anxiety or panic disorder, lung diseases etc. Please, consult a doctor for a comprehensive evaluation if you're experiencing these symptoms.
