Asthma vs. Bronchitis — What's the Difference?
By Tayyaba Rehman & Maham Liaqat — Updated on March 9, 2024
Asthma is a chronic respiratory condition marked by airway inflammation, while bronchitis involves the inflammation of bronchial tubes' lining.

Key Differences
Asthma is characterized by episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or early in the morning. This condition involves the inflammation and narrowing of the airways, leading to difficulty in breathing. Whereas bronchitis, specifically acute bronchitis, is often caused by a viral infection and manifests as a persistent cough that may produce mucus, lasting for several weeks.
Chronic asthma requires long-term management, including the use of inhalers to reduce inflammation and open airways, as well as avoiding known triggers. On the other hand, acute bronchitis typically resolves on its own, though treatments may include rest, increased fluid intake, and sometimes cough medicine to alleviate symptoms.
Asthma can be triggered by various factors, including allergens, exercise, cold air, and stress, leading to an overreaction of the airways. Bronchitis, however, is more commonly triggered by infections, but can also be aggravated by smoking, air pollution, and dust.
Chronic bronchitis is a type of Chronic Obstructive Pulmonary Disease (COPD) and involves a long-term cough with mucus. This is different from asthma, which is primarily an inflammatory reaction that leads to temporary narrowing of the airways.
While both asthma and bronchitis affect the respiratory system, asthma's effects are more on the airways' ability to conduct air, and bronchitis primarily affects the bronchial tubes' lining. This distinction is crucial in understanding their different impacts on breathing and the nature of their symptoms.

Asthma
Asthma is a long-term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms.
Bronchitis
Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that causes coughing. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain.
Asthma
A chronic inflammatory disease of the lungs characterized by a narrowing of the airways and attacks of wheezing, coughing, and shortness of breath that are induced by triggers such as allergens, exercise, infections, and stress.
Bronchitis
Chronic or acute inflammation of the mucous membrane of the bronchial tubes.
Asthma
(pathology) A long-term respiratory condition, in which the airways may unexpectedly and suddenly narrow, often in response to an allergen, cold air, exercise, or emotional stress. Symptoms include wheezing, shortness of breath, chest tightness, and coughing.
Bronchitis
(uncountable) An inflammation of the bronchi of the lungs, that causes the cilia of the bronchial epithelial cells to stop functioning.
Asthma
A disease, characterized by difficulty of breathing (due to a spasmodic contraction of the bronchi), recurring at intervals, accompanied with a wheezing sound, a sense of constriction in the chest, a cough, and expectoration.
Bronchitis
(countable) An occurrence of, a case (patient) of, or a type of bronchitis.
Asthma
Respiratory disorder characterized by wheezing; usually of allergic origin
Bronchitis
Inflammation, acute or chronic, of the bronchial tubes or any part of them.
Bronchitis
Inflammation of the membranes lining the bronchial tubes
Common Curiosities
Is bronchitis contagious?
Acute bronchitis caused by viral infections can be contagious.
Can asthma be cured?
There's no cure for asthma, but it can be managed effectively with treatment.
Can bronchitis turn into pneumonia?
Yes, especially if it's not properly treated or in individuals with weakened immune systems.
Is secondhand smoke a risk factor for both?
Yes, secondhand smoke can exacerbate both asthma and bronchitis.
Is asthma always chronic?
Yes, asthma is a long-term condition that requires ongoing management.
Can children outgrow asthma?
Some children may experience fewer asthma symptoms as they age, but asthma can persist into adulthood.
How is chronic bronchitis diagnosed?
Chronic bronchitis is diagnosed based on symptoms, history of smoking, and lung function tests.
Are inhalers used for bronchitis?
Inhalers are not typically used for acute bronchitis but may be prescribed for chronic bronchitis.
Do asthma and bronchitis have similar treatments?
Some treatments overlap, like inhalers for chronic bronchitis, but the approaches can differ significantly.
Can cold weather trigger both asthma and bronchitis?
Yes, cold air can trigger asthma attacks and may also exacerbate bronchitis symptoms.
Is exercise recommended for individuals with asthma?
Yes, with proper management, people with asthma can still engage in exercise.
Can air pollution affect asthma and bronchitis?
Yes, air pollution can trigger asthma symptoms and exacerbate bronchitis.
Are allergies a common cause of asthma?
Yes, many people with asthma have allergies that can trigger symptoms.
Can stress trigger an asthma attack?
Yes, stress is a known trigger for asthma episodes.
Is a humidifier helpful for bronchitis?
A humidifier can help loosen mucus and alleviate coughing in bronchitis.
