Hyperventilation is breathing that is deeper and more rapid than normal. It causes a decrease in the amount of a gas in the blood. (This gas is called carbon dioxide, or CO2.) The decrease may make you feel light-headed. You may have a rapid heartbeat and be short of breath. It also can lead to numbness or tingling in your hands or feet, anxiety, fainting, and sore chest muscles.
Some causes of sudden hyperventilation include anxiety, fever, some medicines, intense exercise, and emotional stress. It also can occur because of problems caused by asthma or emphysema or after a head injury. But it occurs most often in people who are nervous or tense, breathe shallowly, and have other medical problems, such as lung diseases or panic disorder. It occurs more often in women than men. Most people who have it are 15 to 55 years old. It may occur when people travel to elevations over 2000 m (6500 ft). Symptoms can be like ones from another more serious medical problem, such as a lung problem.
Acute (sudden) hyperventilation is usually triggered by acute stress, anxiety, or emotional upset. Chronic (recurring) hyperventilation may be a lasting problem for people with other diseases, such as asthma, emphysema, or lung cancer.
Many women have problems with hyperventilation when they are pregnant. But it usually goes away on its own after the baby is born.
In many cases, hyperventilation can be controlled by learning proper breathing techniques.
Symptoms usually last 20 to 30 minutes. They may include:
Other symptoms may occur less often. You may not realize that they are directly related to hyperventilation. These symptoms can include:
Hyperventilation isn't a disease. But you may need to be checked by your doctor if you keep having symptoms. If you have recurring symptoms, you might be diagnosed with a condition called hyperventilation syndrome (HVS).
Treatment for hyperventilation depends on the cause. Home treatment is usually all that's needed for mild symptoms. Medical treatment may be needed for hyperventilation symptoms that are moderate to severe, that last for a long time, that come back, or that interfere with your daily activities. Treatment usually includes reassurance, stress reduction measures, breathing lessons, or medicine.

Home treatment may help you control your breathing and stop hyperventilation.
Always try steps to control your breathing or belly-breathe first. If these techniques don't work and you don't have other health problems, you might try breathing in and out of a paper bag that covers your nose and mouth.
First, sit down and concentrate on your breathing.
Breathe through pursed lips, as if you're whistling.
Or pinch one nostril, and breathe through your nose. It's harder to hyperventilate when you breathe through your nose or pursed lips, because you can't move as much air.
Or breathe slowly enough that symptoms gradually go away.
But don't use a paper bag if:
If you use the bag method, follow these precautions.
If you have episodes of hyperventilation that last a long time or occur often, talk to your doctor about your symptoms.
