What is chronic bronchitis?

Chronic bronchitis is a long-term inflammation of the bronchial tubes, which are the airways that carry air to and from the lungs. It is a type of chronic obstructive pulmonary disease (COPD), which is a group of lung diseases that cause airflow blockage and breathing problems.

Chronic bronchitis is characterized by a persistent cough that produces mucus (sputum) and lasts for at least three months in a year, for two consecutive years. The cough may be worse in the morning or when exposed to cold air or irritants. Other symptoms of chronic bronchitis may include:

- Shortness of breath

- Wheezing

- Chest tightness

- Fatigue

- Weight loss

- Increased mucus production

- Frequent chest infections

Chronic bronchitis is often caused by smoking, but other risk factors include exposure to secondhand smoke, air pollution, dust, and chemicals. It is also more common in people with asthma, allergies, and other respiratory conditions.

Treatment for chronic bronchitis usually includes lifestyle changes such as quitting smoking, avoiding irritants, and getting regular exercise. Medications may also be prescribed to help reduce inflammation, relax the airways, and improve airflow. In severe cases, oxygen therapy or surgery may be necessary.
