J41: Simple and mucopurulent chronic bronchitis

Simple and mucopurulent chronic bronchitis, categorized under the group code J41, are chronic pulmonary conditions affecting the bronchi, the air passages that conduct air into the lungs. These conditions are long-term inflammation of the bronchi, leading to an abnormal increase in mucus production and thickening of the bronchial walls. Simple chronic bronchitis is characterized by cough and sputum production for at least three months per year for two consecutive years. In contrast, mucopurulent chronic bronchitis is a more severe form of the disease, with pus-like, thick, yellowish-green sputum due to bacterial infection. The causes can include frequent exposure to irritants like tobacco smoke, dust, or fumes. Both conditions often present chronic cough as the primary symptom, associated with shortness of breath and wheezing. Over time, these conditions can interfere with normal breathing and may lead to severe complications like respiratory failure or heart diseases.
