Thanks for your question on Health Care Magic.
I can understand your concern.
Yes, there is permanent cure for bronchitis.
Bronchitis is actually inflammation of airways. It causes
bronchospasm and this in turn causes cough and breathing difficulty.
So mainstay of treatment is
bronchodilator and anti inflammatory drugs.
But first of all we need to know the severity of bronchitis. And fir this get done PFT (Pulmonary Function Test).
It will tell you about severity of the disease and treatment is based on severity only.
You will improve with inhaled bronchodilators (formoterol,
salmeterol) and inhaled corticosteroid (budesonide or
fluticasone).
Don't worry, you will be alright.
Consult pulmonologist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
