Bronchitis is a condition where the bronchial tubes become inflamed, causing symptoms such as coughing, excess mucus, chest tightness, and trouble breathing. It may develop due to viral or bacterial infections, or from exposure to irritants like cigarette smoke and air pollution. Acute bronchitis usually clears within a few weeks, while chronic bronchitis is a long‑lasting form often associated with smoking or ongoing environmental exposure.

Common symptoms include tiredness, wheezing, and a cough that can be more noticeable at night. Management generally focuses on easing discomfort with rest, plenty of fluids, inhalers, or medications when needed. Some people also find relief with simple home measures like steam inhalation or honey. If symptoms don’t improve or begin to worsen, it’s important to speak with a doctor to rule out complications such as pneumonia.
