Bronchitis is an inflammation of the bronchial tubes, which carry air to and from the lungs. It can be acute, often caused by viral infections, or chronic, usually resulting from long-term irritants like smoking or pollution. Symptoms typically include a persistent cough, production of mucus, wheezing, and shortness of breath. Treatment focuses on relieving symptoms and may involve rest, fluids, and medications.
