Bronchitis

For me, one of the causes that caused bronchitis was living in a city that had very bad air pollution, so as I breathed in, it started to affect my health.

I got bronchitis a lot as a kid. One of the main reasons for me was that I had allergies and asthma. So like my allergies would hit and then it would flare up my asthma and it eventually would turn into bronchitis. I got it like I think it was once a year from like fourth grade to seventh grade or something like that. But yeah that was the cause for mine was just a mixture of allergies and asthma.
