Bronchitis (Medical Definition) | Quick Explainer Video

Bronchitis is a medical condition characterized by inflammation of the bronchial tubes, which are the airways that carry air to and from the lungs. This inflammation can cause a persistent cough, difficulty breathing, chest discomfort, and excessive mucus production. There are two main types of bronchitis: acute bronchitis, which is usually caused by a viral infection and can last for a few weeks, and chronic bronchitis, which is a long-term condition often associated with smoking or exposure to irritants. Treatment for bronchitis may include rest, hydration, cough suppressants, and in some cases, antibiotics. It is important to seek medical attention if symptoms persist or worsen.
