Hello My Uncle has scarring of the lungs and about 7 year ago he had a stent put in This has worked OK apart from chest infections occasionally cleared up by anti biotics.For about 3 months now he has had what some would describe as a cold but its not obviously lasting all this time. He is 86 years old slim build and no weight problem.He is about 5 8 tall Thank you
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you should consult pulmonologist for your uncle. Scarred lungs can cause bronchitis and chronic lung infection like tuberculosis. And both of them can cause recurrent cough with expectoration. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PUT (pulmonary function test) 3. CT thorax. He may need inhaled bronchodilator and inhaled corticosteroids (ICS) and anti-tubercular Chat Doctor.  Don't worry, he will be alright. First diagnose the cause and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wishing good health to your uncle. Thanks.
