Bronchitis is an inflammation, or swelling, of the bronchial tubes in our respiratory system. These tubes are responsible for carrying air from our nose and mouth to our lungs. When we have bronchitis, the walls of these tubes become irritated and produce more mucus than usual. The excess mucus makes us cough and may lead to difficulty breathing.

Bronchitis can be caused by viruses, like the common cold or flu, or bacteria. It typically starts with a sore throat, congestion, and a mild cough that gradually worsens. In some cases, it can lead to chest discomfort and wheezing. Bronchitis can last for a few days to several weeks, depending on the cause and severity.

Treatment for bronchitis usually involves rest, drinking plenty of fluids, and using over-the-counter medications to relieve symptoms such as fever or pain. Antibiotics are only prescribed if bacteria are the cause of the infection. It’s important to avoid smoking and exposure to secondhand smoke, as they can worsen bronchitis symptoms and prolong recovery.
