Bronchitis Causes and Symptoms

Bronchitis is an inflammation of the airways between the windpipe and the lungs (bronchial tubes). The lining of these tubes produces large amounts of mucus, triggering a lingering cough. About one person in 20 in North America suffers from chronic bronchitis. Women are more at risk than men. People with bronchitis typically are smokers over 45 years of age.

Bronchitis Causes

There are two types of bronchitis:Acute bronchitis comes on rapidly, usually after a virus has invaded the upper respiratory tract. Sometimes there is a bacterial infection as well. Viruses most likely to trigger acute bronchitis are those responsible for influenza (the flu) or the common cold. The viruses that cause measles and rubella (German measles) can also cause acute bronchitis. In these cases, it is called acute infectious bronchitis. The condition is called acute irritate bronchitis when it is caused by inhaling dust, fumes, or smoke.

Chronic bronchitis is defined as a mucous-producing cough that lasts for at least three months in two consecutive years. The most important cause by far is smoking. Exposure to some pollutants can also contribute to chronic bronchitis. A growing number of specialists believe that some kind of infection is a necessary final trigger of chronic bronchitis.

About 90% of people with chronic bronchitis are smokers. Certain jobs such as coal mining, welding, asbestos work and grain handling also increase the risk of developing bronchitis.

Bronchitis Symptoms and Complications

Persistent coughing accompanied by mucus or phlegm is the most obvious symptom of bronchitis. Lung congestion and wheezing are also common.

Acute bronchitis usually starts out as a dry cough, but within a few hours or days the cough starts to produce thick mucus. This phlegm typically has a yellow or greenish colour. Wheezing after coughing is usual, and there might be some chest pain as well. Other symptoms are similar to that of a common cold, such as muscle aches, tiredness, and sore throat. A mild fever of about 101°F (38.5°C) may last about four days. A higher temperature, or a fever that isn’t gone within a week, may suggest a bacterial infection such as pneumonia. It’s important to see a doctor in this situation.

Chronic bronchitis features regular coughing and spitting up of a great deal of thick mucus – up to an ounce a day. This mucus can partly block the airways, making breathing difficult. The condition is often dismissed as smoker’s cough. The coughing is often ignored until the lungs have already been damaged.

The result is chronic obstructive pulmonary disease (COPD). This can lead to a chronic lack of oxygen. Signs such as blue lips and nail beds may be noticed. People with this condition tend to become sedentary. The mucous in the airways creates a good environment for viruses and bacteria to breed. This makes people with chronic bronchitis and COPD more prone to other infections such as pneumonia.

It’s important to be aware that symptoms of chronic bronchitis can suddenly get worse.If your medication no longer seems to be effective, see your doctor immediately.

    I, too, am prone to sore throat. I asked my doctor about it. Basically he told me that if I suffer the same soreness for several days, I should go in. Also if the sore throat accompanies a fever to go in right away. Sounds like you have a variety of sore throats. One could come from draining sinuses (after/during a cold or allergies).Try a dose of Tylenol and if that doesn’t help in 48 hours, see a doctor.
