COPD (Chronic obstructive pulmonary disease) is two kinds of long-term lung diseases – chronic bronchitis and emphysema which often occur together.
As a type of lung disease, most of the causes of COPD are about the air you breathe in. Cigarette smoking is the main reason for COPD. Also if you breathe the smoke of cigarette a lot, it can also have a big chance to cause COPD. If you need to work at construction or factory, you may be exposed to things like dust, air pollution, or certain chemicals for long time. At this condition, you can also get COPD easily.
In rare cases, the genes play an important role in getting COPD. People who lack a protein called AAT (alpha 1 antitrypsin) may develop it easily. If you smoke and have COPD, it tends to get worse faster than normal people.
If you fit any condition above and feel uncomfortable when you breathe, call the doctor to check.
