Cause Of Chronic Bronchitis: Cause Of Chronic Bronchitis
The study - led by Cardiff University in the UK - shows for the first time the calcium-sensing receptor (CaSR) plays a key part in causing the airway disease. Daniela Riccardi, principal investigator and a professor in Cardiff's School of Biosciences, describes their findings as "amazingly exciting," because for the first time they have linked airway inflammation - that may be triggered for example by cigarette smoke and car fumes - with airway twitchiness. She adds: "Our paper shows how these triggers release substances 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 significant 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 diseases including asthma, COPD, cystic fibrosis and even certain cancers.
Chronic bronchitis is a common respiratory disorder in the USA. The most common reason for chronic bronchitis is smoking, and the threat of chronic bronchitis increases with the longer you smoke. Healthful lifestyle practices, including hand washing to prevent illness, drinking lots of fluids, following a well balanced diet, getting plenty of rest, and refraining from smoking, improve your symptoms and can reduce your risk of chronic bronchitis. Seek prompt medical care if you are being treated for chronic bronchitis but light symptoms recur or are persistent.

Chronic Obstructive Pulmonary Disease
Tobacco smoking is the most common reason for COPD, with a number of other variables including air pollution and genetics playing a smaller role. The most common symptoms of COPD are shortness of breath, sputum production, and a productive cough. COPD is more common than any other lung disease as a cause of cor pulmonale. Badly ventilated cooking fires fueled by coal or biomass fuels like wood and animal dung, lead in developing countries and are one of the most common reasons for COPD to indoor air pollution.
Chronic Bronchitis Symptoms, Treatment and Contagious
Bronchitis is considered chronic when a cough with mucus continues for at least two years in a row, and at least three months, for most days of the month. Bronchitis occurs when the trachea (windpipe) and the big and small bronchi (airways) within the lungs become inflamed due to illness or annoyance from other causes. Chronic bronchitis and emphysema are types of a condition characterized by progressive lung disease termed chronic obstructive pulmonary disease (COPD).
Herbal Remedies for Cough Sometimes even after a cold disappears, the cough remains for days. This makes a lot of stress on the throat and the stomach muscles, which usually get sore and injure.Fortunately, there are some successful herbal remedies for cough which can be...
- Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs.
- What are the symptoms of chronic bronchitis?
- Inflamed bronchi create lots of mucus, causing the cough and difficulty getting air in and from the lungs.
- Treatment will help your symptoms, but chronic bronchitis is a long term condition that never goes away.
Acute bronchitis is usually due to viruses, generally the exact same viruses that cause colds and flu (influenza). Antibiotics do not kill viruses, so this sort of medicine isn't useless in most cases of bronchitis. The most common reason for chronic bronchitis is smoking cigarettes.
What are the Symptoms of Chronic Bronchitis?
Cough is really a defense mechanism developed by the body in an effort to clear the airways of mucus or other kinds of like cigarette smoke and air pollution irritate the airways resulting in inflammation and an overproduction of mucus. Shortness of breath is often worsened by activity or exercise. Insufficient oxygen causes dyspnea in the bloodstream and is among the most common symptoms of chronic bronchitis. In chronic bronchitis, the bronchi (airways) become damaged and thickened, which alters the protective activity of the bacteria-fighting cells within the lungs.
The combination of increased mucus and damage to the bronchi makes a patient with chronic bronchitis more susceptible to lung infections. Wheezing is a high pitched whistling sound made during breathing and is brought on by a narrowing, or blockage, of the airways. Swelling (particularly of the lower extremities) and weight gain may accompany chronic bronchitis and frequently happen due to side effects of certain medicines used to treat the have questions about chronic bronchitis symptoms?
