Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, by his history and description, possibility of chronic
bronchitis is more.
Treatment of bronchitis is based on severity only. And fir severity, PFT (pulmonary function test) is must.
So first of all, get done PFT to know the severity of the disease.
He may need newer longer acting inhaled bronchodilators like (indacaterol and glycopyrollium) for better symptomatic relief.
Oral bronchodilator, acebrophyllin is also indicated in severe bronchitis.
Oral
antioxidants like n acetyl
cysteine (NAC) is also beneficial in his case.
Chest physiotherapy and deep breathing exercises are also helpful in improving lung functions and reduce symptoms.
So
consult pulmonologist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
