Bronchitis is a common disease in clinical practice. Patients often experience symptoms such as cough, expectoration, wheezing, and chest tightness. So, is bronchitis hereditary after contracting it? Bronchitis is not a genetic disease and is not hereditary. The causes of bronchitis in patients are often due to infections, physical and chemical irritations, allergies, and other factors, and are not largely related to genetics. Moreover, bronchitis can generally be controlled with active treatment.
