Thanks for your question on Health Care Magic.
I can understand your concern.
You should consult pulmonologist
(lung specialist) for your wife.
She is mostly having asthma
So consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (Pulmonary Function Test).
3. Chest x ray
Chest x ray is needed to rule other lung pathology.
PFT is must for the diagnosis of asthma. It will also tell you about severity of the disease and treatment of asthma is based on severity only.
She needs regular inhaled bronchodilators and inhaled corticosteroid (ICS).
Oral combination of antihistamine and anti allergic drugs are also indicated.
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 wife. Thanks.
