Causes And Effects Of Bronchitis: Chronic Bronchitis Symptoms, Treatment and Contagious
Bronchitis is considered chronic when a cough with mucus lasts for most days of the month, for at least three months, and at least two years in a row. Bronchitis occurs when the trachea (windpipe) and the big and small bronchi (airways) within the lungs become inflamed because of infection or irritation from other causes. Chronic bronchitis and emphysema are types of an illness defined by progressive lung disease termed chronic obstructive pulmonary disease (COPD).
Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. Bronchitis may be either long-term or acute. Chronic bronchitis, an ailment that is more serious, is a continuous irritation or inflammation of the lining of the bronchial tubes, often due to smoking. Chronic bronchitis is one of the conditions contained in chronic obstructive pulmonary disease (COPD).
Bronchitis Causes and Effects?

But since most cases of bronchitis are viral in origin or caused by lung irritants like smoke and pollutants, antibiotics would not do any good.
The study - led by Cardiff University in the UK - reveals for the first time that 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 "incredibly 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 purpose of CaSR in airway tissue could have significant implications for other respiratory ailments such as chronic obstructive pulmonary disease (COPD), chronic bronchitis. The researchers, from Washington University School of Medicine in St. Louis, believe their findings will lead to treatments for a variety of disorders including asthma, COPD, cystic fibrosis and even certain cancers.

Continued episodes of acute bronchitis, which weaken and irritate bronchial airways over time, can result in chronic bronchitis.
Acute bronchitis is usually caused by viruses, typically the same viruses that cause colds and flu (influenza). Antibiotics do not kill viruses, so this type of medicine isn't useless in most cases of bronchitis. The most common cause of chronic bronchitis is smoking cigarettes.
Acute upper respiratory tract infections (URTIs) comprise colds, influenza and diseases of the throat, nose or sinuses. Saline nose spray and bigger volume nasal washes have grown to be very popular as one of several treatment alternatives for URTIs, and they've been demonstrated to have some effectiveness for chronic sinusitis and following nasal operation. This is a well-conducted systematic review and the decision seems dependable. Find all (14) Outlines for consumersCochrane authors reviewed the available evidence from randomised controlled trials on the utilization of antibiotics for adults with acute laryngitis. Acute upper respiratory tract infections (URTIs) contain colds, flu and infections of the throat, nose or sinuses. This review found no evidence for or against the use of increased fluids in acute respiratory infections.
Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD) is the term used to describe chronic lung illnesses that cause acute shortness of breath and block the airways in your lungs. Your doctor may also order a chest x-ray to try to find over-expanded places in the lungs; a CT scan to assess the severity of your COPD; an examination of your sputum; or a blood test to measure the amounts of oxygen and carbon dioxide in your blood. One study indicated that taking ginseng helped folks with COPD improve lung function and their exercise tolerance.
