Respiratory and other symptoms of hypocarbia. Since hypocapnia is based on chronic hyperventilation, its symptoms are the same as the symptoms of hyperventilation. They are very wide and range from chronic coughing and nasal congestion, to constipation, coughing and muscle cramps.
This is caused by the brain which controls the level of carbon dioxide in the blood. When the brain detects a low concentration of carbon dioxide, it tends to slow the process of breathing in order to return the carbon dioxide level to equilibrium. In some cases, hypocapnia will cause no outward symptoms. As the body breathes normally, the co2 level will normalize itself. There is a risk that the lack of carbon dioxide might cause a constriction of the blood vessels that feed blood to the brain. This becomes a medical emergency because there is a sudden fall in the level of oxygen in the brain. This situation is known as hypoxia.
