brochitis and COPD
Bronchitis is a respiratory condition characterized by inflammation and irritation of the bronchial tubes, which are the airways that carry air to and from the lungs. It can be classified into two main types: acute bronchitis and chronic bronchitis. **1. Acute Bronchitis:** - Acute bronchitis is a common condition and is usually caused by viral infections, such as the flu (influenza) or the common cold (rhinovirus). - It can also be caused by bacterial infections, though less frequently. - Acute bronchitis is typically self-limiting, and symptoms often improve within a few weeks without specific medical treatment. - Symptoms of acute bronchitis include: - Cough (initially dry and irritating, which may later produce mucus or phlegm) - Sore throat - Runny or stuffy nose - Mild fever - Fatigue - Shortness of breath or wheezing in some cases **2. Chronic Bronchitis:** - Chronic bronchitis is a more serious and long-term form
