Causes of bronchitis

Bronchitis and the main symptoms

Bronchitis is a medical term for the disease marked by the inflammation of the linings of bronchial tubes, which have the role to transport air to the lungs as well as from the lungs. There are several types of bronchitis and the least serious is mild bronchitis, which usually occurs because of the cold or some respiratory infection. On the other side, chronic bronchitis is serious because in this condition frequent inflammations, usually caused by smoking, affect the lining of the bronchial tubes. Chronic bronchitis needs medical treatment and this condition belongs to chronic obstructive pulmonary diseases.

Bronchitis, as each disease, has its characteristic warning signs and symptoms, and the most common are cough, slight chills or fever and chest discomfort. Furthermore, the increased production of clear, white, yellowish-gray or green sputum is quite normal for bronchitis, and in addition to this signs, shortness of breath, fatigue and wheezing may also appear.

Chronic bronchitis can develop even in the case when acute bronchitis was not present, whereas, after acute bronchitis, a person who suffered from it may continue to cough for several weeks, and that is normal. Acute bronchitis usually does not need any treatment and disappears after a few days, but it is very important to visit the doctor when the cough is severe and prevents sleeping. Furthermore, the persistent low-grade fever, long-lasting cough, and chronic lung or heart problems are only some of the conditions that must be reported to the physician. Bronchitis can be caused by viruses, bacteria or some other factors that irritate the bronchial tubes.

Causes of acute bronchitis

Acute bronchitis can be causes by the same viruses that are responsible for the development of colds. Moreover, this type can appear as a result of tobacco smoking or due to the exposure to some pollutants, such as smog or some household cleaners. Acute bronchitis may develop when the stomach acid enters esophagus and several drops of it reach upper airway. This condition is known under the name gastroesophageal reflux disease. Occupational bronchitis is a type of acute bronchitis that can occur when a person is constantly exposed to dusts or fumes.

Causes of chronic bronchitis

Chronic bronchitis is a serious disease and in most cases it is caused by smoking. In addition to smoking, some other factors can lead to the occurrence of this disease, such as air pollution and dust or toxic gases in the environment. The doctors usually prescribe some antibiotics, cough medicines or bronchodilators. Anti-inflammatory medicines and glucocorticoid steroids are also very effective in treating bronchitis.
