Asthma, emphysema, and bronchitis are diseases of the lung airways. All three conditions affect breathing, but they can differ in their severity, causes, and treatment.
Emphysema and bronchitis can be part of chronic obstructive pulmonary disease (COPD), which also causes a narrowing of the airways.
Emphysema involves the destruction of tiny air sacs, or alveoli, in the lungs. Bronchitis involves inflammation of the bronchial tubes resulting in coughing with mucus production.
In this article, we will compare the symptoms, severity, transmission, causes, and treatment of all three conditions.
- blue or gray lips or nails
- chest pain
- unexplained weight loss
- abnormal heartbeat
Additionally, people with all three conditions may experience worsening symptoms or flares, most often occurring during winter.
The severity of asthma ranges from intermittent, where people experience symptoms occasionally, to severe persistent, where people experience symptoms regularly. However, the symptoms of asthma
In some cases, asthma symptoms worsen with time due to exposure to specific allergens. This results in a significant reduction in lung function.
The severity of emphysema and bronchitis, which can be part of COPD illnesses, can also range from mild to severe. Severe COPD may cause damage to the lungs and lead to airflow blockage.
However, overall, COPD is more severe than asthma. Asthma is a reversible condition that improves when a person receives the right medicines and treatment. On the contrary, COPD is a progressive disease that worsens over time and is not curable.
Both asthma and emphysema are noncommunicable diseases, which means they are not contagious and cannot spread from one person to another.
Acute bronchitis can be
Several risk factors can cause asthma, emphysema, and bronchitis.

According to the American Lung Association, people are 3–6 times more likely to develop asthma if they have a biological parent with the condition.
Other common causes of asthma include:
- allergies such as rhinitis or eczema
- respiratory infections during childhood or infancy
- occupational exposure to dust and chemical fumes
However, the triggers that can cause asthma vary from one person to another.
Emphysema and bronchitis
Smoking is the most common cause of COPD, which can include emphysema and bronchitis.
Other causes of COPD include:
- exposure to secondhand smoke
- occupational exposure to chemicals, dust, and fumes
- history of asthma and other childhood respiratory infections
- alpha-1 antitrypsin deficiency, which is a rare genetic condition
- exposure to indoor air pollution, such as from burning coal or biomass fuel
Treatment methods will vary from person to person and depend on the condition they have.
The primary goal of asthma treatment is to reduce the severity and frequency of symptoms.
Doctors recommend treatment approaches according to the seriousness of the condition, the age of the person, and their response to the medication.
Quick-relief medications include:
- oral corticosteroids
- inhaled short-acting beta2-agonists (SABAs)
- short-acting anticholinergics
Long-term control medications include:
Doctors recommend bronchial thermoplasty only in severe cases that do not respond to other traditional treatments. Bronchial thermoplasty can decrease thick muscle in the airways.
Doctors may also recommend nonpharmacological treatments to help reduce the symptoms of mild cases of bronchitis.
- hot tea
- throat lozenges
They may also recommend:
- beta-agonists to reduce wheezing
- analgesic and antipyretic medications to help ease fever or malaise
- steroids to improve inflammation
Treatment approaches doctors may recommend for emphysema
Surgery is the last resort for people with a severe disease that does not improve with medications.
Asthma, emphysema, and bronchitis are diseases of the airways of the lungs, and the latter two can be part of COPD. These conditions share a few common symptoms. However, COPD, being a progressive disease, is more severe than asthma.
Transmission of bronchitis can take place from one person to others. Asthma and emphysema do not spread directly. Several factors are responsible for the development of asthma, emphysema, and bronchitis.
Many treatment approaches are also available depending on the severity of the condition and the age of the person.
People with symptoms should consult a doctor at an early stage to help avoid developing a severe form of these conditions.
