Thanks for your question on Healthcare Magic.
I can understand your concern.
By his symptoms, history and barrel shaped chest, possibility of COPD (chronic
obstructive pulmonary disease) is more in his case.
It is progressive disease of lungs.
Cigarette smoking is the biggest risk factor for this.
So he should definitely quit smoking as soon as possible.
Other treatment options are as follows.
1. Enroll him in
pulmonary rehabilitation center where
chest physiotherapy any deep breathing exercises are done.
2.
Consult pulmonologist and get done PFT (pulmonary function test) to rule know the severity of the disease. Treatment is based on severity only. He will need inhaled bronchodilator (formoterol order salmeterol) and inhaled corticosteroids (ICS) (budesonide or fluticasone).
3. Give him adult respiratory vaccines like influenza and pneumococcal to prevent recurrent
respiratory tract infection.
So consult pulmonologist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wishing him good health. Thanks.
