Is there any problem in my lungs?

Q: I am a 22 years old man facing problem while breathing. Whenever I breathe for a short time (>20 sec) in a rapid manner through nose, I get dizzy and develop stomach cramps, which subside in a minute. Why is this happening? Are my lungs weak or damaged?

A:Rapid breathing can lead to hyperventilation and depletion of carbon dioxide in the blood. This can cause the symptom you are suffering from. To evaluate the functioning of the lungs, there is test called spirometry along with clinical evaluation, which can diagnose any lung disease.
