Study Notes

Asthma

Asthma, also known as bronchial asthma, is a respiratory condition that makes breathing difficult.
Airways (bronchi) narrow due to inflammation of the airway lining.
Inflammation makes the airways more sensitive to irritants, triggering symptoms.

Asthma Symptoms

Main symptoms include coughing, wheezing, and shortness of breath.
Coughing occurs due to irritated and twitchy airways.
Wheezing is a high-pitched sound caused by air whistling through narrowed airways.
Shortness of breath results from the body working harder to breathe.

Asthma Triggers

Triggers don't cause asthma, but they provoke symptoms or attacks.
Common triggers include virus infections, exercise, emotional factors, stress, atmospheric changes, and allergies.

Viral Infections

Colds and flu are common triggers.

Exercise

All exercise, especially running, can trigger asthma within minutes.

Emotional Factors and Stress

Excitement, especially in children, and laughter can be triggers.
Stress worsens asthma symptoms.

Atmospheric Conditions

Weather changes, particularly cold and dry air, can trigger symptoms.

Allergies

Allergies are a major trigger for many people, even more than viruses.
Common allergens include house dust, feathers, animal fur, grass and tree pollens, and mold spores.

Causes of Asthma

Asthma is caused by airway narrowing due to inflammation of the airway lining.
Inflammation leads to muscle spasms, swelling, and overproduction of mucus.
These factors reduce airway size, leading to wheezing and shortness of breath.

Asthma and Viruses

Asthma is not a virus.
Asthma is a condition caused by airway inflammation.
Viruses are infectious agents that invade human cells and cause illness.
Common colds, caused by rhinoviruses or influenza viruses, can trigger asthma attacks.

Asthma and Allergies

Asthma and allergies are not the same, but asthma can be triggered by allergic reactions.
Allergies occur when a person is sensitive to common substances (such as pollen, dust mites, or pet hair) that don't affect most people.
