[/INST] Thanks for your question on Chat Doctor. Bronchiectesis is chronic, structural disease of lung causing dilated bronchi. In this dilated bronchi, secretions tend to accumulate and cause infection and inflammation. These in turn cause more coughing and difficulty in breathing So treatment of bronchiectasis is antibiotic, Multics, cough expectorant and inhaled bronchodilators. Better to consult pulmonologist and get done chest x-ray to rule out infection. Newer Multics and expectorant are N Acetyl Cysteine (NAC), aerosol and bromine. You may need inhaled treatment also. So consult pulmonologist and discuss all these. </s>
