My 71 yr old mother has had a persistent cough for about 4 years.  Three years ago she had a chest x-ray that said she had mild bilateral bronchitis.  She had another chest x-ray just six months ago and again in says she has bilateral bronchitis.  The doctor said the cough could be from her blood pressure medicine, so they prescribed something different.  Shouldnt they be treating her for bronchitis?
Hello thanks for posting at Chat Doctor. Since you have mentioned that your mother is suffering from cough from four years and x-ray reports bronchitis, she definitely has obstructive airway disease (OAD). Blood pressure medications like beta blockers can worsen OAD symptoms, but stopping them doesn't mean bronchitis will get treated. She definitely needs to be treated for her bronchitis or OAD with inhalers and tablets. For that we have to establish baseline lung function by doing a pulmonary function test. This will show if she has obstructive airways and the severity of obstruction. On basis of above information by PFT she can be started on medications. Please do a PFT and revert with the results. Wishing you good healthRegards.
