bronchitis
INFLAMMATION of the BRONCHI , which occurs in two forms, acute and chronic. Bacteria or viruses cause the acute form, which is initially typified by the symptoms of the common cold but develops, with painful coughing, wheezing, throat and chest pains and the production of purulent (pus-containing) mucus. If the infection spreads to the BRONCHIOLES (bronchiolitis) the consequences are more serious as the body is deprived of oxygen. Antibiotics and expectorants can relive the symptoms. Chronic bronchitis is identified by an excessive production of mucus and may be the result of recurrence of the acute form. It is a common cause of death among the elderly, and there are several parameters of direct consequence to its cause: excessive smoking of cigarettes; cold damp climate; obesity; respiratory infections. Damage to the bronchi and other complications may occur, giving rise to constant BREATHLESSNESS .
Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. It causes a cough that often brings up mucus. It can also cause shortness of breath, wheezing, a low fever, and chest tightness. There are two main types of bronchitis: acute and chronic.
Most cases of acute bronchitis get better within several days. But your cough can last for several weeks after the infection is gone.
The same viruses that cause colds and the flu often cause acute bronchitis. These viruses spread through the air when people cough, or though physical contact (for example, on unwashed hands). Being exposed to tobacco smoke, air pollution, dusts, vapors, and fumes can also cause acute bronchitis. Less often, bacteria can also cause acute bronchitis.
To diagnose acute bronchitis, your health care provider will ask about your symptoms and listen to your breathing. You may also have other tests.
Treatments include rest, fluids, and aspirin (for adults) or acetaminophen to treat fever. A humidifier or steam can also help. You may need inhaled medicine to open your airways if you are wheezing. Antibiotics won't help if the cause is viral. You may get antibiotics if the cause is bacterial.
