Causes For Recurring Bronchitis: Bronchitis Causes
Acute bronchitis is usually due to viruses, normally the exact same viruses that cause colds and flu (influenza). Antibiotics do not kill viruses, so this sort of medication isn't useless in most cases of bronchitis. The most common reason for chronic bronchitis is smoking cigs.
The study - led by Cardiff University in the UK - shows for the first time that the calcium-sensing receptor (CaSR) plays a key role in causing the airway disorder. Daniela Riccardi, principal investigator and a professor in Cardiff's School of Biosciences, describes their findings as "very exciting," because for the first time they have linked airway inflammation - which can be activated for example by cigarette smoke and car fumes - with airway twitchiness. She adds: "Our paper shows how these triggers release compounds that activate CaSR in airway tissue and drive asthma symptoms like airway twitchiness, inflammation, and narrowing.
Prof. Riccardi concludes: The researchers believe their findings about the function of CaSR in airway tissue could have important consequences for other respiratory ailments such as chronic obstructive pulmonary disease (COPD), chronic bronchitis. The researchers, from Washington University School of Medicine in St. Louis, consider their findings will lead to treatments for a variety of disorders including asthma, COPD, cystic fibrosis and even certain cancers.
Causes of Acute and Chronic Bronchitis (Persistent Cough)
Bronchitis is one of the more common lower respiratory tract illnesses and may happen in isolation or involve nearby structures like the trachea or lung tissue (parenchyma). The most common cause of acute bronchitis is an illness while in chronic bronchitis, cigarette smoking is a leading contributing factor. Numerous viruses including those associated with the seasonal flu (influenza), common cold, and other acute respiratory tract infections (ARTI) like the respiratory syncytial viruses (RSV's) are the common cause.
Acute bronchitis often develops along with or towards the latter phases of these viral infections which also impacts other parts of the respiratory tract pharyngitis (sore throat), laryngitis and tracheitis. According to the causative factor, it can result in repeated episodes of acute bronchitis which may lead to chronic bronchitis. Hence some of the causes mentioned above for acute bronchitis if recurrent or persistent may result in chronic bronchitis.
Acute Bronchitis vs. Chronic Bronchitis

Diseases of the Lung
Bronchitis is the inflammation of the bronchi, the main air passages to the lungs, it typically follows a viral respiratory infection. You need to have a cough with mucus most days of the month for at least 3 months, to be diagnosed with chronic bronchitis. The symptoms of either kind of bronchitis include: Cough that produces mucus; if yellow-green in color, you are more likely to have a bacterial illness Shortness of breath worsened by exertion or mild activity Even after acute bronchitis has cleared, you may have a dry, nagging cough that lingers for several weeks.
You can Find Two Types of Bronchitis: Acute (Short Term) and Chronic (Long-Term)
Babies, young kids, and the elderly have an increased risk of developing acute bronchitis, while smokers and people over 45 years of age are most likely to develop chronic bronchitis. Smoking is the most common reason for chronic bronchitis and may also lead to acute bronchitis. Treatment for chronic bronchitis includes bronchodilators, anti-inflammatory drugs, for loosening mucus in the lungs and chest physical therapy. Seek prompt medical care if you are being treated for bronchitis but moderate symptoms recur or are persistent.
Most Individuals With Chronic Bronchitis Have Chronic Obstructive Pulmonary Disease (COPD)
Tobacco smoking is the most common cause, with several other variables like genetics and air pollution playing a smaller part. Symptoms of chronic bronchitis may include wheezing and shortness of breath, especially. Most cases of chronic bronchitis are due to smoking cigarettes or other kinds of tobacco. Furthermore, persistent inhalation of irritating fumes or air pollution or dust from dangerous exposures in occupations like livestock farming, grain handling, textile manufacturing, coal mining, and metal moulding can also be a risk factor for the development of chronic bronchitis. Unlike other common obstructive ailments including asthma or emphysema, bronchitis scarcely causes a high residual volume (the volume of air remaining in the lungs after a maximal exhalation effort).
