Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. People who have bronchitis often cough up thickened mucus, which can be discolored. Bronchitis may be either acute or chronic.
The most common cause of bronchitis is however viral infection. The symptoms of viral bronchitis are wheezing, burning pain, difficulty in breathing, and headache. Viral bronchitis can disappear on its own without medications, with simple home remedies.
How does bronchitis occur?
The same viruses that give you cold or flu cause bronchitis. Though, bacteria too can cause bronchitis.
- The flu virus spreads through contact with an infected person, and through coughing and sneezing. When people who are infected, cough or sneeze, droplets are released into the air. People nearby inhale these droplets and get exposed to the virus.
- Infection also spreads when unsuspecting people touch any surface, contaminated with the droplets of cough and sneezing of an infected person, and then touch their mouth or nose.
Almost all respiratory viruses spread this way.
- When the germs enter your body, your immune system fights the germs, and during this phase, the bronchial passages may swell up and gear into action to create more mucus. This results in smaller openings for the air to flow through making it difficult to breathe for you. This is when bronchitis occurs.
- People with bronchitis suffer from reduced ability to fully breathe in oxygen into their lungs due to the heavy mucus or phlegm congesting their airways.
There are two types of bronchitis:
Acute Bronchitis: lasts for a shorter duration and commonly occurs after a cold or viral infection, such as the flu. It causes cough with mucus, fever, headache, and chest discomfort. It can last from three to four days to upto three to four weeks. Acute bronchitis is contagious.
Chronic Bronchitis: is a persistent form of bronchitis that can last for upto three months or even upto two years. It is caused by repeated irritation and damage of the lung and airway tissue and is caused by air pollution, dust and fumes.
- Don’t wait or self medicate.

- bacterial infection
The causes of chronic bronchitis include:
- chronic smoking
- long-term exposure to air pollution, dust and fumes

Diagnosis of bronchitis
A general practitioner can easily diagnose the symptoms of bronchitis. He will ask about the symptoms and in particular the cough and also about your medical history, and if you have recently suffered from a cold or flu. He will also ask if you have other health conditions and if you smoke, or if you have recently been exposed to substances such as dust, fumes, vapours, or air pollution.He will perform a quick medical exam with a stethoscope to listen for any abnormal sounds in the lungs.
Based on the severity of your condition the doctor may recommend:
- X-ray of the chest: to determine if you are suffering from pneumonia
- Sputum test: if you have any other illnesses such as whooping cough
- Pulmonary function test: to check the condition of your lungs and also see if you have any other medical condition such as asthma.
What are the complications of bronchitis?
Some complications of bronchitis include:
- dyspnea
- pneumothorax
- polycythemia
- emphysema
- respiratory failure
- pneumonia
- cor pulmonale (alteration in the structure of the right ventricle in the heart)
- chronic advancement of the disease
What is the treatment for bronchitis?
- If the bronchitis is due to bacteria the doctor will prescribe antibiotics. For viral bronchitis, he may prescribe a cough suppressant and pain reliever. You will also be asked to take plenty of fluids and be on bed rest.
- In cases of acute bronchitis, you may need inhalers and other forms of treatment. Make sure that you tell the doctor all your pre-existing medical conditions (that is if you have any) so that the doctor can prescribe medicines which do not clash with each other.
Prevention from bronchitis
To reduce your risk of bronchitis, follow these tips:
- Avoid cigarette smoke. Cigarette smoke increases your risk of chronic bronchitis.
- Get vaccinated. Many cases of acute bronchitis result from influenza, a virus. Getting a yearly flu vaccine can help protect you from getting the flu. You may also want to consider vaccination that protects against some types of pneumonia.
- Wash your hands. To reduce your risk of catching a viral infection, wash your hands frequently and get in the habit of using alcohol-based hand sanitizers.
- Wear a surgical mask. If you have COPD, you might consider wearing a face mask at work if you’re exposed to dust or fumes, and when you’re going to be among crowds, such as while traveling.
Complications of bronchitis
Although a single episode of bronchitis usually isn’t cause for concern, it can lead to pneumonia in some people. Repeated bouts of bronchitis, however, may mean that you have chronic obstructive pulmonary disease (COPD).
When to see a doctor
- See your doctor if your cough lasts more than three weeks
- Prevents you from sleeping
- Is accompanied by fever higher than 100.4 F (38 C)
- Produces discolored mucus
