My husband cough a lot and spits up phlegm does he have copd?

Many different cause: Though these care common symptoms of early COPD (chronic bronchitis) there are many other reasons for this. Smoking of course is a prime cause but work related causes are also suspect. If he works in a factory or other workplace where there is a lot of dust or other things (ie sawdust, chemicals, etc) you may want to start there. Either way, to make sure have him tested by a physician.
