What is bronchitis?
The inflammation of your bronchial tubes (bronchi), which are the air passages between the mouth, nose, and the lungs, is a condition known as bronchitis. This illness can be caused by viruses, bacteria, as well as allergens such as tobacco smoke, dust, fumes, vapours, and air pollution.
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.
