Bronchitis is an inflammation of the bronchial tubes, which carry air in and out of the lungs during respiration. There are two types of bronchitis: acute and chronic. Acute bronchitis is common, occurring frequently as a complication of a cold or other respiratory infection. Chronic bronchitis, however, is less common and more serious. A person is considered to have the chronic form when the bronchitis lasts longer, up to several months, and occurs more frequently, two or more times a year. Chronic bronchitis may be a precursor of chronic obstructive pulmonary disease (COPD). Visit Premier Urgent Care in Harvest and Huntsville for immediate treament and for chronic broncitis.
Causes of Bronchitis
Although a typical case of bronchitis is caused by a virus (a cold or influenza), it can be complicated by a bacterial infection. If bronchitis remains viral, antibiotic treatment will not help. However, if bacteria are present, antibiotics may be necessary and helpful.
Pollutants often make the respiratory system susceptible to bronchial infection. The most common pollutant is cigarette (or cigar or pipe) smoke. Many people who suffer chronic bronchitis are smokers or live in smoke-filled environments. Dust, air pollution and airborne toxins, whether at home or in the workplace, make developing bronchitis more likely.
Risk Factors for Bronchitis
Some people are at much greater risk of developing bronchitis than others. The following factors increase the likelihood of contracting bronchitis:
- Smoking or being exposed to secondhand smoke
- Living or working in an environment polluted by chemical fumes
- Having severe gastroesophageal reflux disease (GERD)
- Being asthmatic
Babies or young children, the elderly, and those with underlying diseases/conditions that compromise their immune systems are also more likely to develop bronchitis.
Symptoms of Bronchitis
Symptoms of acute or chronic bronchitis include the following:
- Tightness in the chest
- Cough with clear or colored mucus
- Low-grade fever and chills
- General malaise and fatigue
- Shortness of breath
If symptoms last more than a few days, or if they include the following, a doctor at Premier Urgent Care should be consulted; our clinc are located nearby Athens, Owens Cross Roads, Hazel Green, Big Cove, Moores Hill, Triana, Meridianville, Madison and New Hope. No appointment is necessary.
- Inability to sleep due to coughing or wheezing
- Shortness of breath, or difficulty breathing
- Sputum that is yellow or greenish, or streaked with blood
Patients who have asthma, a disorder in which there is muscle tightening and swelling around the airways, tend to be prone to a form of bronchitis called "asthmatic bronchitis." They often have more severe symptoms and should seek medical care.
Diagnosis of Bronchitis
In order to diagnose bronchitis, the doctor takes a medical history and performs a physical examination. Listening to the patient's breathing through a stethoscope is important, because it allows the doctor to detect wheezing and, to a certain extent, congestion. A mucous sample may be obtained to check for bacterial infection. Usually, the patient's oxygen level is measured with an oximeter. Other diagnostic tests may be used, particularly if pneumonia, or some other complication, is suspected. These tests include chest X-rays, lung-function tests and blood tests.
Treatment of Bronchitis
If the bronchitis is viral, it usually resolves on its own in a few days. Resting and drinking fluids can decrease discomfort, and speed healing. If symptoms are severe or persistent, a physician, who may prescribe antibiotics or administer further tests, should be consulted. Patients who have chronic asthmatic bronchitis may be treated with corticosteroid inhalers or other medications, sometimes administered through a nebulizer, to keep their airways open. Patients with chronic respiratory ailments should be vaccinated for influenza and pneumonia.
