Bronchitis is a condition where the airways in your lungs (bronchi) become inflamed and irritated, leading to a persistent cough, chest congestion, wheezing, and difficulty breathing. It can be acute, which is usually caused by a viral infection like the common cold and lasts for a few weeks, or chronic, which is a long-term condition often linked to smoking, pollution, or other lung diseases. Acute bronchitis usually improves with rest, fluids, and over-the-counter medications, while chronic bronchitis may require long-term treatment, including inhalers or lifestyle changes. If your cough lasts more than three weeks, worsens over time, or causes breathing difficulties, it’s important to visit a doctor for proper diagnosis and care.
