Recurrent bronchitis, a condition that requires consideration of a number of factors, can be seen in chronic respiratory diseases, such as wheezing bronchitis, and also in bronchial asthma, which tends to develop acute attacks of chronic diseases when the body’s immunity is reduced by triggering factors such as fatigue, exposure to cold and rain. In addition, it is also seen in the case of other chronic diseases that themselves make the resistance lower, such as uncontrolled diabetes, uncontrolled lung diseases, such as pulmonary heart disease, etc., where recurrent attacks of bronchitis can occur when the body’s resistance is lowered. Also, it is seen in specific diseases, such as AIDS, leukemia, aplastic anemia, etc. These underlying diseases with poorer resistance are also prone to infection with pathogens and bronchitis.
