Bronchitis seems to hit just when you think that your cold or cough is finally getting better. In addition to being painful, bronchitis makes it difficult to sleep and results in lost days from school or work. While the primary symptom of bronchitis is a persistent cough, there are several other symptoms you should know about.
Identification
Bronchitis affects the bronchial passages that carry oxygen throughout the lungs. When the mucus membranes in the bronchial passages become irritated, they swell and produce excess mucus. The combination of the swelling and the excess mucus narrows small airways in the lungs, which results in coughing and difficulty breathing.
Types
Acute bronchitis usually lasts 6 weeks or less, and can be caused by the same types of viruses that cause colds. These viruses are easily spread, and you can catch one if someone releases the virus into the air by sneezing. Shaking hands with an infected person can also be enough to transmit a virus, making it a good idea to regularly wash your hands during cold season.
Chronic bronchitis lasts for 3 months or longer, and is often caused by smoking, as cigarette smoke irritates the bronchial passages, causing excess mucus to be produced. Lengthy exposure to dust, fumes, chemicals or other irritants can also cause chronic bronchitis.
Features
A persistent, mucus-producing cough is the main symptom of bronchitis. The mucus you cough up will usually be yellow or green, indicating an infection. You may also experience fever, chills, wheezing, trouble breathing, chest soreness, or a burning or heavy feeling in your chest. You may find it difficult to perform everyday activities without becoming tired or out of breath.
Everyone does not experience the same symptoms, and some people with bronchitis produce more mucus than others. If you have a cough that won't go away and you are feeling unwell, it's a good idea to visit your doctor for a definitive diagnosis.
