What Causes Recurring Bronchitis: Bronchitis Causes
Acute bronchitis is generally caused by viruses, normally precisely the same viruses that cause colds and flu (influenza). Antibiotics do not kill viruses, so this type of medication isn't useless in most cases of bronchitis. The most common cause of chronic bronchitis is smoking cigs.
Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. You can find two principal types of bronchitis: acute and long-term. Chronic bronchitis is one sort of COPD (chronic obstructive pulmonary disease). The inflamed bronchial tubes produce lots of mucus. To diagnose chronic bronchitis, your doctor listen to your breathing and will look at your signs and symptoms. Chronic bronchitis is a long-term state that never goes away completely or keeps coming back.
What are the Causes of Recurring Bronchitis?
Regular or long-term exposure to pollution, dust or other air irritants can lead to recurring bronchitis. The lungs can be damaged by the irritants over time and produce a dry cough in people who have bronchitis. Individuals who smoke or are exposed to secondhand smoke may increase the risk of developing diseases due to exposure. By staying from the substances that cause it a lot of people can avoid future bouts with bronchitis. Gastroesophageal reflux disease, known as GERD, causes stomach acid to always back up into the esophagus, and can result in long-term cough and bronchitis.
The study - led by Cardiff University in the UK - reveals for the very first time the calcium-sensing receptor (CaSR) plays a vital role in causing the airway disease. Daniela Riccardi, principal investigator and a professor in Cardiff's School of Biosciences, describes their findings as "unbelievably exciting," because for the first time they've linked airway inflammation - which may 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 role of CaSR in airway tissue could have important consequences for other respiratory illnesses 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 range of diseases including asthma, COPD, cystic fibrosis and even certain cancers.
Causes of Acute and Chronic Bronchitis (Persistent Cough)
Bronchitis is among the more common lower respiratory tract illnesses and may happen in isolation or call for 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 factor that is contributing. 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 periods of these viral infections which also influences other parts of the respiratory tract pharyngitis (sore throat), laryngitis and tracheitis. Based on the causative factor, it can lead to repeated episodes of acute bronchitis which can lead to chronic bronchitis. Thus any of the causes mentioned above for acute bronchitis if recurrent or persistent may lead to chronic bronchitis.
Treatment of bronchitis mostly includes the alleviation of symptoms and, in cases of chronic bronchitis, minimising damage. Bronchitis, which may affect anyone, is one of the most common ailments for which medical advice is sought by people. Because of this, chronic bronchitis is regarded as a sort of chronic obstructive pulmonary disease (COPD), which will be a progressive and irreversible condition of decreased lung function. The most common cause of acute bronchitis is viral infection (90% of cases), but bacterial illness and environmental irritants are also causes.
Nearly All Individuals Identified as Having Chronic Bronchitis are Aged 45 Years or Old
People with chronic bronchitis can experience acute exacerbation (worsening) of their bronchitis, usually (in 70-80% of instances) due to an infection of the airways. The most obvious symptom of acute bronchitis is a short-term dry hacking cough, which can become a productive cough that produces sputum that is white or yellow. Children aged less than five years infrequently have parents will often hear a rattling sound in the chest and a productive cough sputum is typically seen in vomit.
The most common symptoms of chronic bronchitis are a repeated or persistent productive cough, wheezing, and gradually worsening shortness of breath. Continuing disease of the airways can also be an indication of chronic bronchitis. Because many symptoms of chronic bronchitis are not dissimilar to those of other lung ailments it's important that a doctor is consulted for a proper analysis. In acute bronchitis, coughing normally lasts between 10 to 20 days. Because most cases of acute bronchitis, also as acute exacerbations of chronic bronchitis, are caused by the common cold or flu, it helps to take measures to cease the spread of these viruses such as the following: The principal goal of treatment for chronic bronchitis is to control symptoms and to prevent additional airway damage and narrowing.
Diseases of the Lung
Bronchitis is the inflammation of the bronchi, the main air passages to the lungs, it normally follows a viral respiratory infection. You must 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 type of bronchitis include: Cough that produces mucus; if yellow-green in colour, you might be 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.
