Bronchitis
Description
Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to and from the lungs. It can be acute (short-term) or chronic (long-term). Acute bronchitis is often caused by viral infections, while chronic bronchitis is commonly associated with smoking and long-term exposure to irritants. Symptoms include persistent coughing, production of mucus (sputum), wheezing, and shortness of breath, chest discomfort, and mild fever. In acute bronchitis, symptoms may last for a few weeks, whereas chronic bronchitis lasts for months and often recurs. Treatment depends on the type. Acute bronchitis usually resolves on its own, with rest, hydration, and over-the-counter medications to relieve symptoms. Chronic bronchitis may require bronchodilators, steroids, and pulmonary rehabilitation. Prevention includes avoiding smoking, reducing exposure to pollutants, and practicing good hygiene.
