Bronchitis does not usually leave sequelae and can usually be completely cured with regular treatment. If acute bronchitis is not cured for a long time or is not treated regularly, it may cause chronic bronchitis. Chronic bronchitis tends to recur, and each time the symptoms are worse than the last. If you are suffering from acute bronchitis, it is best to go to the hospital in time to find out the cause of the disease, to clarify whether it is caused by bacterial infection or viral infection, or mycoplasma or chlamydia infection, and then to carry out targeted treatment according to the different causes, which can generally be completely cured in about a week. And chronic bronchitis requires not only inflammation control, but also daily life conditioning.
