Respiratory alkalosis is a condition marked by low levels of carbon dioxide in the blood due to breathing excessively.
See also: Alkalosis
Common causes include:
- Pregnancy (this is normal)
Any lung disease that leads to shortness of breath can also cause respiratory alkalosis (such as pulmonary embolism and asthma).
The symptoms may include:
- Numbness of the hands and feet
Treatment is aimed at the condition that causes respiratory alkalosis. Breathing into a paper bag -- or using a mask that causes you to re-breathe carbon dioxide -- sometimes helps reduce symptoms.
What will happen depends on the condition that is causing the respiratory alkalosis.
Seizures may occur if the alkalosis is extremely severe. This is very rare.
When to Contact a Medical Professional
Call your health care provider if you have any symptoms of lung disease, such as chronic cough or shortness of breath.
