<s>[INST] Hi my son is 1 year and was diagnosed with bronculitis. its been a month since hes been out of hospital but the cough is back and he still has gas when coughing even though he went through physio theraphy while in hospital what could be the corse of this cough [/INST] Thanks for your question on Health Care Magic. I can understand your concern. Bronchiolitis is inflammation of small airways. Most common cause for this is lung infection. Inflammation causes bronchospasm and cough. This needs antibiotics, inhaled bronchodilators and inhaled corticosteroid (ICS). So consult pulmonologist and discuss all these. He will need inhaled treatment for complete recovery. Usual time of recovery is 1-2 months. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks. </s>
