Bronchitis

Bronchitis is an inflammation of the bronchial tubes, which are air passages in the lungs. It can be acute or chronic. Acute bronchitis is usually caused by viral infections, while chronic bronchitis is often linked to smoking or long-term exposure to irritants. Symptoms include coughing, wheezing, chest discomfort, and sometimes fever. Treatment typically involves rest, hydration, and symptom management. Antibiotics are usually not necessary unless there's a bacterial infection present. Chronic bronchitis requires lifestyle changes like quitting smoking and sometimes medication to manage symptoms and prevent complications.
