Thanks for your question on Health Care Magic.
I can understand your concern.
Most common cause for
bronchitis is
lung infection.
So in my opinion, you should
consult pulmonologist for your wife and get done
1. Clinical examination of respiratory system
2. Chest
x ray 3. PFT (Pulmonary Function Test). Chest x ray is needed to rule out lung infection.
PFT is must for the diagnosis of bronchitis. It will also tell you about severity of the disease and treatment of bronchitis is based on severity only.
She may need antibiotic, anti
histamine, anti inflammatory drugs, inhaled bronchodilators and inhaled corticosteroid (ICS).
Don't worry, she will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
