What effect does chronic bronchitis have on the lungs?
People with chronic bronchitis have chronic obstructive pulmonary disease (COPD). This is a large group of lung diseases that includes chronic bronchitis. These diseases can block air flow in the lungs and cause breathing problems.
What is the main problem in chronic bronchitis?
Chronic bronchitis. In this condition, your bronchial tubes become inflamed and narrowed and your lungs produce more mucus, which can further block the narrowed tubes. You develop a chronic cough trying to clear your airways.
How serious is chronic bronchitis?
There are two main types, acute and chronic. Unlike acute bronchitis, which usually develops from a respiratory infection such as a cold and goes away in a week or two, chronic bronchitis is a more serious condition that develops over time. Symptoms may get better or worse, but they will never completely go away.
Does bronchitis damage your lungs?
The increased mucus causes airflow obstructions. Over time, chronic bronchitis can lead to permanent damage to the lungs, such as decreased lung function.
What is the main cause of bronchitis?
In most cases, bronchitis is caused by the same viruses that cause the common cold or flu. The virus is contained in the millions of tiny droplets that come out of the nose and mouth when someone coughs or sneezes. These droplets typically spread about 1m (3ft).
What are the risk factors of chronic bronchitis?
Risk FactorsBreathing in chemicals, dust, and other substances for a long time.Smoking cigars or marijuana for a long time.Being around secondhand smoke.Having family members with chronic obstructive pulmonary disease (COPD)Having a lot of lung infections as a child.Having asthma for a long time.
What is the best treatment for chronic bronchitis?
Bronchodilator Medications Inhaled as aerosol sprays or taken orally, bronchodilator medications may help to relieve symptoms of chronic bronchitis by relaxing and opening the air passages in the lungs. Steroids Inhaled as an aerosol spray, steroids can help relieve symptoms of chronic bronchitis.

What causes mucus to build up in the airways?
These extended periods of inflammation cause sticky mucus to build up in the airways, leading to long-term breathing difficulties. Along with emphysema, chronic bronchitis is one of the lung diseases that comprise COPD (chronic obstructive pulmonary disease).
What tests are used to diagnose bronchitis?
Tests used to diagnose chronic bronchitis include pulmonary function tests, chest X-rays or CT scans. Chronic bronchitis is not curable but there are a number of treatments that can help you manage your symptoms.
How long does it take for bronchitis to go away?
Unlike acute bronchitis, which usually develops from a respiratory infection such as a cold and goes away in a week or two, chronic bronchitis is a more serious condition that develops over time. Symptoms may get better or worse, but they will never completely go away.
Why do I cough so much?
This irritation can cause severe coughing spells that bring up mucus, wheezing, chest pain and shortness of breath. There are two main types, acute and chronic.
Is chronic bronchitis a COPD?

Your doctor may refer to your disease as either chronic bronchitis or COPD. Cigarette smoking is a major cause of chronic bronchitis. Other factors that increase your risk of developing this disease include exposure ...
What are the factors that increase the risk of developing bronchitis?
Other factors that increase your risk of developing this disease include exposure to air pollution as well as dust or toxic gases in the workplace or environment. It may also occur more frequently in individuals who have a family history of bronchitis.
What are the symptoms of chronic bronchitis?
Other symptoms of chronic bronchitis may include: fatigue. a fever.
How to get rid of bronchitis?
You may want to consider the following: Breathing in warm, moist air from a humidifier can ease coughs and loosen the mucus in your airways.
What is the inflammation of the lining of the bronchial tubes?
Bronchitis is an inflammation of the lining of the bronchial tubes. These are the tubes that carry air to and from your lungs. People who have bronchitis often have a persistent cough that brings up thickened, discolored mucus. They may also experience wheezing, chest pain, and shortness of breath. Bronchitis may be either acute or chronic.
Why does bronchitis make my lungs swell?
Chronic bronchitis occurs when the lining of the bronchial tubes repeatedly becomes irritated and inflamed. The continuous irritation and swelling can damage the airways and cause a buildup of sticky mucus, making it difficult for air to move through the lungs. This leads to breathing difficulties that gradually get worse.
What does it mean when you cough up mucus?
After a long period of inflammation and irritation in the bronchial tubes, chronic bronchitis can result in several hallmark symptoms, including a persistent, heavy cough that brings up mucus from the lungs. The mucus may be yellow, green, or white. As time passes, the amount of mucus gradually increases due to the increased production ...
What is the name of the condition where the lungs are blocked?
Together, the two conditions are referred to as chronic obstructive pulmonary disease, or COPD.
How long does bronchitis last?
It’s characterized by recurrent episodes of bronchitis that last for several months or years.
What causes coughing and mucus production?
by John Bottrell Health Professional. April 14, 2014. April 14, 2014. Chronic bronchitis is a lung disease that causes a cough with increased mucus production for at least three months in two consecutive years. It generally falls under the category of chronic obstructive pulmonary disease, or COPD. The most common cause is cigarette smoking, ...
What is the term for a thickened bronchial wall?
Bronchial walls become thick and scarred: This is often referred to as airway remodeling. It occurs when inflammation lasts for such a long time that the body tries to fix it. This results in scar tissue, causing the airways to become fibrotic, or stiff. This damage is permanent and there is no treatment for it.
Why do goblet cells increase in number?
Goblet cells increase in number: This also causes increased mucus production. 3. Bronchial walls become inflamed: This is due to repeated exposure to the harmful chemicals of cigarette smoke. These chemicals injure the walls, and the body's attempt to fix them causes them to become inflamed or swollen.
What is the best treatment for bronchitis?
A good treatment technique for this is to exhale through pursed lips, thus allowing more time for trapped air to get out. 10. Emphysema: Most people with chronic bronchitis also suffer from emphysema, which is the breakdown or destruction of lung tissue, which is probably also caused by inflammation.
Why is lung anatomy important?
Knowledge of lung anatomy is helpful because long-term exposure to inhaled cigarette smoke may cause changes inside the airways. 1.
Why do my airways spasm?
Bronchospasm: Inflamed airways are extra sensitive to certain triggers (such as inhaled irritants, allergens, and strong smells) that may cause flare-ups. This may cause the muscles wrapping around the airways to spasm. Flare-ups are discussed in my recent post " COPD flare-up causes .".
What are the symptoms of cyanosis?
Common symptoms of this are dyspnea and cyanosis, or a blue tinge around the fingertips and lips. Treatment for this is wearing oxygen. 13. Hypercapnia: Along with allowing less oxygen to get to the blood, less carbon dioxide (CO2) will be allowed to leave the blood and enter the lungs to be exhaled.
What is COPD in pulmonary disease?
Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) that is defined as a productive cough of more than 3 months occurring within a span of 2 years. Patients typically present with chronic productive cough, malaise, and symptoms of excessive coughing such as chest or abdominal pain. This activity reviews the evaluation and management of chronic bronchitis and explains the role of the interprofessional team in improving care for patients with this condition.
What is the most common symptom of chronic bronchitis?
The most common symptom of patients with chronic bronchitis is a cough. The history of a cough typical of chronic bronchitis is characterized to be present for most days in a month lasting for 3 months with at least 2 such episodes occurring for 2 years in a row. A productive cough with sputum is present in about 50% of patients. The sputum color may vary from clear, yellow, green or at times blood tinged. The color of sputum may be dependent on the presence of secondary bacterial infection. Very often changes in sputum color can be due to peroxidase released by leucocytes in the sputum. Therefore, color alone is not a definite indication of bacterial infection.
How long does bronchitis last?
Chronic bronchitis can be defined as a chronic productive cough lasting more than 3 months occurring within a span of 2 years. There is a strong causal association with smoking and is very often secondary to chronic obstructive pulmonary disease (COPD). [1]
What is the primary goal of bronchitis treatment?
The primary aim of treatment for chronic bronchitis is to relieve symptoms, prevent complication and slow the progression of the disease. The primary goals of therapy are aimed at reducing the overproduction of mucus, controlling inflammation and lowering cough. These are achieved by pharmacological as well as nonpharmacological interventions. [5][6][7]
What is the best treatment for chronic bronchitis?
Pulmonary rehabilitation is an important part of treatment for chronic bronchitis is pulmonary rehabilitation which consists of education, lifestyle modification, regular physical activity and avoidance of exposure to known pollutants either at work or living environment. [8]
What is the most critical factor in the diagnosis of chronic bronchitis?
The most critical factor in the diagnosis of chronic bronchitis is a typical history to exclude other possible diseases of the lower respiratory tract.
What are the causes of chronic bronchitis?
There are many known causes of chronic bronchitis, but the most important causative factor is exposure to cigarette smoke either due to active smoking or passive inhalation. Many inhaled irritants to the respiratory tract such as smog, industrial pollutants, and toxic chemicals can cause chronic bronchitis. Although bacterial and viral infections usually cause acute bronchitis repeated exposure to infections can cause chronic bronchitis. The predominant viruses that are causative are Influenza type A and B, and the dominant bacterial agents are Staphylococcus, Streptococcus, and Mycoplasma pneumonia. People who have an associated background in respiratory diseases such as asthma, cystic fibrosis, or bronchiectasis have a higher predisposition to develop chronic bronchitis. People who have repeated exposure to environmental pollutants such as dust or airborne chemicals such as ammonia and sulfur dioxide have a higher risk of developing chronic bronchitis. Chronic gastroesophageal reflux is a well documented but less frequent cause of chronic bronchitis. [1]
What causes mucus to be overproduced?
Mucous metaplasia, a process in which mucus is overproduced in response to inflammatory signals, is the pathologic foundation for CB. The primary mechanisms responsible for excessive mucus in COPD are overproduction and hypersecretion by goblet cells and decreased elimination of mucus. Mucus hypersecretion develops as a consequence of cigarette smoke exposure (34, 35), acute and chronic viral infection (36), bacterial infection (37), or inflammatory cell activation of mucin gene transcription via activation of the epidermal growth factor receptor (37). This leads to overproduction of mucus and hypersecretion from increased degranulation by neutrophil-mediated elastase. This is compounded by difficulty in clearing secretions because of poor ciliary function, distal airway occlusion, and ineffective cough secondary to respiratory muscle weakness and reduced peak expiratory flow (37–39). Figure 1summarizes the causes of excessive mucus in COPD.
What is COPD in the US?
Chronic obstructive pulmonary disease (COPD) is a common disease characterized by irreversible airflow obstruction and persistent inflammation to noxious environmental stimuli, usually cigarette smoke. It affects 12 to 16 million people in the United States and is the third leading cause of death and disease burden worldwide (1). COPD encompasses a spectrum of diseases, with chronic bronchitis (CB) at one end and emphysema at the other, with most individuals having some characteristics of both. The CB definition used in epidemiologic studies has been variable, but the classic definition is chronic cough and sputum production for at least 3 months per year for two consecutive years (2). CB has numerous clinical consequences, including an increased exacerbation rate, accelerated decline in lung function, worse health-related quality of life (HRQoL), and possibly increased mortality (3–6). We review the clinical phenotype of CB, the current understanding of its pathophysiology, and treatment options.
What are the cytokines produced by T cells?
The inflammatory mechanisms responsible for mucous metaplasia in COPD are poorly understood. T cells have been classically divided into two main populations, Th1 and Th2. Th1 cells produce cytokines such as IL-1, IL-6, and IFN-γ, whereas the cytokines produced by Th2 cells are IL-4, IL-5, and IL-13. Mucous metaplasia has been extensively described as an end product of Th2 inflammation and has been extensively studied in asthma, a disease with Th2 inflammation central to its pathophysiology (51, 52). However, the cellular response associated with COPD has been most frequently (although not exclusively) attributed to the inflammatory Th1 arm of the acquired immune system. Therefore, it would seem unlikely that patients with COPD would develop mucous metaplasia given the dominance of Th1 inflammation in the pathophysiology of COPD. However, recent advances in our understanding of effector T cell biology has revealed the existence of a second distinct subpopulation of CD4+T cells with particularly potent proinflammatory functional activities (53). These cells are designated Th17 cells because of their capacity to produce IL-17A and IL-17F.
What percentage of COPD patients have a productive cough?
Chronic productive cough: 60% in subjects with COPD
Is CB a risk factor for respiratory-related deaths?
CB is a risk factor for respiratory-related deaths. Prescott and colleagues found that chronic mucus hypersecretion in hospitalized patients with COPD was associated with an increased risk of death by pulmonary infection (63). Respiratory symptoms of cough and phlegm in 8,427 white U.S. adults over a 9- to 12-year observational period were associated with increased COPD-related mortality (24). In addition, Pelkonen and colleagues found an increased risk of respiratory-related death when CB was present (22).
What magnification is the Schiff stain?
Periodic acid fluorescent Schiff stain of a small airway from a patient with advanced emphysema. The entire airway is seen at ×10 magnification in Aand a quadrant of the airway at ×40 in B. Mucin granules are shown in redalong the apical border of the epithelium. Note the large intraluminal mucin plug (M) in A, also noted in B(white arrow). Reprinted by permission from Reference 120.
What are the risk factors for CB?
However, it should be noted that CB has been described in 4 to 22% of never smokers (15, 22), suggesting that other risk factors may exist. Other potential risk factors include inhalational exposures to biomass fuels, dusts, and chemical fumes (30, 31). A national household survey of South African adults found occupational exposure to be a risk factor for CB in men (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.7–4.0) and exposure to smoky domestic fuels to be a risk factor for CB in women (OR, 1.9; 95% CI, 1.4–2.6) (27). In a recent analysis of 5,858 smokers or ex-smokers without COPD, patients with CB were more likely to have been exposed to fumes at work (76.4 vs. 60.9%, P< 0.001) or to have worked more than 1 year at a dusty job (76 vs. 57%, P< 0.001) (19). Another potential risk factor for CB is the presence of gastroesophageal reflux, possibly by pulmonary aspiration of refluxed gastric contents producing acid-induced injury and infection or neurally mediated reflex bronchoconstriction secondary to irritation of esophageal mucosa (32, 33).
Lifestyle changes
Some lifestyle factors can help you live better with chronic bronchitis. Examples include:
Medications
Doctors will often prescribe medications to help your lungs work as well as they can. Examples of medications doctors prescribe include:
What color is sputum?
For either acute bronchitis or chronic bronchitis, signs and symptoms may include: Production of mucus (sputum), which can be clear, white, yellowish-gray or green in color — rarely, it may be streaked with blood. If you have acute bronchitis, you might have cold symptoms, such as a mild headache or body aches.
What is the inflammation of the lining of the bronchial tubes?
Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. People who have bronchitis often cough up thickened mucus, which can be discolored. Bronchitis may be either acute or chronic.
What to wear when you have COPD?
Wear a surgical mask . If you have COPD, you might consider wearing a face mask at work if you're exposed to dust or fumes, and when you're going to be among crowds, such as while traveling.
Can smoking cause bronchitis?
Cigarette smoke. People who smoke or who live with a smoker are at higher risk of both acute bronchitis and chronic bronchitis. Low resistance. This may result from another acute illness, such as a cold, or from a chronic condition that compromises your immune system.
Can bronchitis cause pneumonia?
Although a single episode of bronchitis usually isn't cause for concern, it can lead to pneumonia in some people. Repeated bouts of bronchitis, however, may mean that you have chronic obstructive pulmonary disease (COPD).
Can chronic bronchitis cause periods?
If you have chronic bronchitis, you're likely to have periods when your cough or other symptoms worsen. At those times, you may have an acute infection on top of chronic bronchitis.
Can antibiotics kill bronchitis?
Antibiotics don't kill viruses, so this type of medication isn't useful in most cases of bronchitis. The most common cause of chronic bronchitis is cigarette smoking. Air pollution and dust or toxic gases in the environment or workplace also can contribute to the condition.
