Definition
Respiratory alkalosis is a condition marked by low levels of carbon dioxide in the blood due to breathing excessively.
See also: Alkalosis
Alternative Names
Alkalosis - respiratory
Causes
Common causes include:
- Anxiety
- Fever
- Hyperventilation
Any lung disease that leads to shortness of breath can also result in respiratory alkalosis.
Symptoms
The symptoms may include:
- Dizziness
- Light-headedness
- Numbness of the hands and feet
Exams and Tests
- Arterial blood gas
- Chest x-ray

Treatment
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.
Outlook (Prognosis)
The prognosis is based on the condition that causes the respiratory alkalosis.
Possible Complications
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.
