Bronchitis

What is Bronchitis?

Bronchitis is the inflammation of the bronchial tubes, which carry air to and from the lungs. This leads to coughing, mucus production, chest discomfort, and difficulty breathing. It can be acute (short-term) or chronic (long-term).

🔹 Chronic Bronchitis – A long-term condition, often due to smoking or air pollution, leading to persistent cough for at least three months per year for two consecutive years.
