Bronchospasm vs. Bronchoconstriction — What's the Difference?
By Tayyaba Rehman — Updated on October 16, 2023
"Bronchospasm is the sudden constriction of bronchi muscles; Bronchoconstriction is the narrowing of bronchi, often more gradual."

Key Differences
Bronchospasm refers to a sudden tightening of the muscles in the walls of the bronchioles. It's often associated with asthma and can come on quickly, causing immediate breathing difficulties. Bronchoconstriction, however, is a narrowing of the airways that can be more gradual, often resulting from inflammation or physical stimuli.
Bronchospasms are considered to be a type of bronchoconstriction, but they're specifically characterized by their rapid onset and severity. Bronchoconstriction is a broader term that refers to any reduction in the diameter of the bronchi, which can be due to a variety of causes, including environmental factors, allergic reactions, or chronic conditions.
Bronchospasms are typically considered more severe and more likely to require immediate medical attention because they can significantly and suddenly restrict airflow. Bronchoconstriction, while it can be severe, often develops more slowly, giving individuals more time to respond to the symptoms.
The triggers for bronchospasm often involve an allergic reaction or a response to irritants. Bronchoconstriction, on the other hand, can be triggered by a wider range of factors, including exercise, cold air, or certain medications, and is a common feature in chronic respiratory diseases.
Both bronchospasm and bronchoconstriction can be treated with bronchodilators, which work to relax the tightened muscles around the airways. However, because bronchospasm is often more sudden and severe, its occurrence might indicate the need for a more aggressive or immediate treatment approach.

Compare with Definitions
Bronchospasm
"A sudden constriction of the muscles in the walls of the bronchioles."
He experienced a bronchospasm during the intense smoke exposure.
Bronchoconstriction
"A reduction in the diameter of the bronchi, usually due to an environmental factor or health condition."
During her run, she experienced bronchoconstriction and had to stop.
Bronchospasm
"An acute tightening of the bronchial muscles causing breathing difficulties."
The doctor diagnosed her coughing and wheezing as a bronchospasm.
Bronchoconstriction
"Constriction of the airways, often due to a response such as inflammation or a reaction to medication."
The patient's bronchoconstriction was found to be a side effect of a new medication.
Bronchospasm
"A spasm of bronchial smooth muscle producing narrowing of the bronchi."
High pollen levels in the air can trigger a bronchospasm in sensitive individuals.
Bronchoconstriction
"The narrowing of the airways in the lungs due to the tightening of surrounding smooth muscle."
Cold weather can often lead to bronchoconstriction in some individuals.
Bronchospasm
"A rapid constriction of the airways, often in response to an allergen or irritant."
During the concert, she suffered a bronchospasm and needed her inhaler.
Bronchoconstriction
"A condition characterized by increased resistance in the bronchi, leading to breathing difficulties."
She manages her bronchoconstriction with daily medication and lifestyle changes.
Bronchospasm
"A sudden and severe episode of airway tightening resulting in shortness of breath."
Experiencing a bronchospasm, he quickly used his emergency medication.
Bronchoconstriction
"A physiological response that narrows the airways and reduces airflow to the lungs."
He is careful when gardening, as pollen causes bronchoconstriction.
Bronchospasm
Bronchospasm or a bronchial spasm is a sudden constriction of the muscles in the walls of the bronchioles. It is caused by the release (degranulation) of substances from mast cells or basophils under the influence of anaphylatoxins.
Bronchoconstriction
Bronchoconstriction is the constriction of the airways in the lungs due to the tightening of surrounding smooth muscle, with consequent coughing, wheezing, and shortness of breath.
Bronchospasm
A contraction of smooth muscle in the walls of the bronchi and bronchioles, causing them to constrict.
Bronchoconstriction
(medicine) A narrowing of the air passages through the bronchi of the lungs
Bronchospasm
(medicine) difficulty in breathing due to a contraction of smooth muscle in the walls of the bronchi and bronchioles
Bronchospasm
A spasm of the bronchi that makes exhalation difficult and noisy; associated with asthma and bronchitis
Common Curiosities
Are bronchospasms life-threatening?
They can be severe and even life-threatening if not promptly treated, as they significantly restrict airflow.
Is bronchospasm the same as an asthma attack?
They are closely related; an asthma attack may involve a bronchospasm, which is the sudden tightening of the airway muscles.
Can anxiety cause bronchospasm?
Anxiety doesn't directly cause bronchospasm but can worsen breathing problems during an episode.
Can bronchoconstriction occur without an asthma diagnosis?
Yes, bronchoconstriction can be triggered by various factors like allergens or exercise, not just asthma.
How is exercise-induced bronchoconstriction managed?
It can be managed with pre-exercise medication, warm-ups, and avoiding cold, dry air.
What are common symptoms of bronchoconstriction?
Symptoms include shortness of breath, wheezing, coughing, and a tight feeling in the chest.
Can weather changes trigger bronchospasm?
Yes, shifts in weather, especially cold air, can trigger bronchospasm in sensitive individuals.
Can bronchoconstriction be completely cured?
It's typically managed rather than cured, often with medication and trigger avoidance.
Are certain populations more prone to bronchoconstriction?
Yes, people with respiratory illnesses, allergies, or high pollution exposure may experience more bronchoconstriction.
What medications treat bronchospasm?
Quick-relief inhalers (bronchodilators) are commonly used to treat sudden bronchospasms.
Are there long-term effects of repeated bronchoconstriction?
Chronic bronchoconstriction can contribute to the development of conditions like COPD.
Does bronchospasm affect lung function over time?
Repeated severe bronchospasms can affect lung function, emphasizing the need for proper management.
Can diet impact bronchospasm or bronchoconstriction frequency?
A healthy diet can improve overall health, potentially reducing the frequency, though direct impacts need more research.
What lifestyle changes help manage bronchoconstriction?
Avoiding triggers, using air purifiers, and practicing breathing exercises can help.
Are children more susceptible to bronchospasms?
Children, particularly those with asthma, are indeed more prone to bronchospasms.
