Could copd be caused by an early childhood deformity in the lungs?

Not usually: Generally, COPD (chronic obstructive pulmonary disease) refers to a condition occurring in adulthood, usually from tobacco use, although there are some rare other contributing causes. Although we see occasional cases of congenital lung structural abnormalities (like congenital lobar emphysema), which can cause other health issues like recurrent pneumonias, it doesn't seem to lead to copd.

Unlikely: There are some deformities that can cause lung impairment and subsequently shortness of breath such as scoliosis and pectus excavatum. The resulting problem is not considered copd. Cystic fibrosis leads to changes that could be misdiagnosed as copd. Severe lung infections can cause a condition called bronchiectasis, it's main symptom is cough and phlegm.

Not usually...: The vast majority of COPD is caused by cigarette smoking. There is a form of COPD that is genetic, alpha1-anti trypsin deficiency, but this is not due to a deformity, but a decrease in a protein.
