Thanks for your question on Health Care Magic.
I can understand your concern.
Yes, pollution and environmental change can trigger breathing problem.
In my opinion, you are mostly having either
asthma or
bronchitis.
You are having positive family history of asthma, so pollution can trigger it.
Pollution is itself a risk factor for bronchitis.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (Pulmonary Function Test)
3. Chest
x ray.
Chest a ray is needed to rule other lung related causes.
PFT is must for the diagnosis of asthma and bronchitis. It will also tell you about severity of the disease and treatment is based on severity only.
You may need inhaled bronchodilators and inhaled corticosteroid (ICS).
Wear face mask to prevent pollution.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
