Causes of Bronchitis

Bronchitis is one of the most common respiratory infections that could be contracted by both children and adults. This disease affects the respiratory tract and is characterized by coughing spells that are accompanied with greenish or yellowish-gray mucus. Other symptoms that could be seen for bronchitis are just like those that can be seen in upper respiratory tract infections like breathlessness, congestion, filled up sinus cavities, wheezing, fever and chills and overall malaise, among others. There are different causes of bronchitis and somehow their difference also lies on what type of bronchitis is contracted by a person.

When it comes to a person with acute bronchitis, the culprit is almost always the similar viruses that could be contracted and could lead to colds. However, one of the causes of bronchitis, especially the acute kind, could also be found on a person’s exposure to second-hand smoke from cigarettes or from his own cigarette smoking. Smog and household cleaners, which are among the most common pollutants that a person can get in contact with, are also known culprits when it comes to acute bronchitis.

The bronchitis disease may, however, also visit persons who have gastroesophageal reflux disease or GERD. This condition is characterized by the consistent backing up of acids right into the food pipe, from the stomach. Those workers who are also exposed everyday to fumes or certain dusts, which are common causes of bronchitis, could also contract what is known as occupational bronchitis. This is an acute type of bronchitis that usually clears up when its patients refrain themselves from getting exposed to the irritants.

Chronic bronchitis, on the other hand, which is a type of bronchitis where the thickening and inflammation of the bronchial tubes’ lining hasn’t improved for more than three months, also has its own causes and they are more serious ones. One of the major causes of bronchitis that has already progressed into being a chronic disease is smoking. Among the symptoms of chronic bronchitis are a continuous cough that is accompanied with great amounts of mucus being coughed up and shortness of breathing. A person is usually regarded as already having chronic bronchitis if his cough continues on after three months until two years.

There are also other causes of chronic bronchitis, which is a serious and ongoing disease. Among these are air pollution and the exposure to toxic gases and dust either in the workplace or in the environment. There are some cases wherein chronic bronchitis can lead to asthma because of the incessant inflammation of the lung’s airways. So, everyone should be mindful of the coughs that they are experiencing. They should consult with their doctors once they notice that they are coughing yellowish or greenish mucus, as mucus that is neither white nor clear can already suggest secondary infection like bronchitis.
