yes your dad should get a chest xray asap... likely some form of COPD... perhaps Bronchiectasis if he continually produces mucus like that
I am in agreement with bsmsl. I was diagnosed 3 yrs. ago with moderate stage COPD. I too get mucus mainly in my throat. Many times I cannot cough it up. When I can get something up, it is usually white in color. Either your Dad has an upper respiratory infection or could possibly have some form of COPD. Different lung problems fall under the umbrella term COPD....asthma, emphysema and chronic bronchitis. I personally have emphysema and chronic bronchitis.
Your Dad really needs to see a doctor. A lung xray and a simple breathing test called a spirometry will determine if he has COPD. This is not going to go away on its own. I will pray for your Dad to seek medical treatment and this is nothing but an infection. God bless.
This could be several things. I know the constant coughing is annoying to him and ALL those around him. I have a chronic cough with sticky phlegm as well. I know what it is like.
First: He could have asthma of COPD (especially COPD since he was a smoker).
SeconD: He could have a chronic infection that could be treatable. That is the case with me.
I pray that you get some answers soon.
