Bronchitis is a respiratory disease in which the mucous membrane in the lungs' bronchial passages becomes inflamed. In most cases the infection is viral in origin, but sometimes it's caused by bacteria.
Permanent bronchitis (excess smoking while ill) can cause a more permanent condition. This permanent condition is called COPD (chronic obstructive pulmonary disease).
Inflammation of the bronchial tubes +/- bronchii (part of the respiratory system), and it can be caused by infection, dust, allergens, bacteria...

What is acute bronchitis?

Bronchitis is the swelling and irritation in the small air passages in the lungs. In acute bronchitis there is a cough that produces phlegm, and pain behind the breastbone when you breathe deeply or cough.

How does it happen?

Bronchitis is commonly associated with viral infections of the respiratory tract, such as colds and flu. Bacterial infections may also cause acute bronchitis. It may also occur with childhood illnesses, such as measles and whooping cough. Infants, young children and the elderly are most likely to get acute bronchitis. Attacks are most frequent during the winter and when air pollution is high.

What are the symptoms?

There is cough with yellowish or greenish phlegm. Pain occurs behind the breastbone or in the chest on breathing deeply or coughing. Wheezing or breathlessness may be present. Fever with chills along with a headache or sore muscles may occur.

How is it diagnosed?

The doctor will ask about the symptoms and examine the patient’s chest with a stethoscope. Some tests may also be done, such as, sputum analysis (if it is yellowish, greenish or blood-tinged), chest X-ray and some blood tests.

What is the treatment?

Treatment includes taking medicines to relieve the symptoms. Antibiotics are required in bacterial infections. The doctor should be informed about any allergy to antibiotics. Steam inhalation or using a vaporizer helps in recovery. Cough syrups that help liquefy the phlegm may be used. If wheezing is present, bronchodilators may be needed.

How long will the effects last?

In most cases, bronchitis develops suddenly and clears up quickly. The symptoms last from 2 to 4 days. It may take longer to recover in smokers. People having a heart or lung disease, living in an area with air pollution or other health problems may delay recovery.

When should the doctor be consulted?

The doctor must be consulted if the patient doesn't feel better in a couple of days, has breathing trouble, a fever over 100.5 degrees F (38 degrees C) or blood on coughing.

How to prevent acute bronchitis?

Reduce the risk of getting a respiratory infection:


Do not smoke

Exercise regularly

Frequently wash hands

Eat healthy foods

Avoid damp, cold and polluted areas
all of the above,,,the bronchi,are the little air sacs in the lungs,when they get inflamed,it's hard to breath.Also exposure to cigerette smoking,dust,toxic gases in the work environment can cause acute bronchitis.Smokers with chronic bronchitis cough almost every day.
acute bronchitis can be spread from person to person,wash your hands good,or use hand santitizers.
Just when you thought you were finally over a cold, your chest starts to feel sore and you develop a cough. Later, you might get the chills or a slight fever.

If these signs and symptoms sound familiar, you might have acute bronchitis, a condition that occurs when the inner walls that line the main air passageways of your lungs become infected and inflamed.

Bronchitis can be caused by an infection (90% are viral in origin) or exposure to dust, chemicals, air pollution, or cigarette smoke.

Avoiding air pollution is an easy way to decrease bronchitis symptoms. Avoiding foods containing processed sugar or flour may decrease the amount of mucus in the lungs.

Most cases of acute bronchitis disappear within a few days without lasting effects, although coughs may linger for weeks. If you have repeated bouts of bronchitis, see your doctor. You may have a more serious health problem — such as asthma or chronic bronchitis — that needs medical attention.

All the best.
