Study Notes
What is Asthma?
- Asthma is a respiratory condition that causes difficulty breathing
- Airways, or bronchi, narrow, making it harder for air to move in and out of the lungs
- Inflammation of the airway lining causes airways to be reactive, leading to exaggerated responses to irritation
Symptoms of Asthma
- Coughing: Irritated and twitchy airways cause coughing
- Wheezing: Narrowed airways create a high-pitched whistling sound
- Shortness of breath: Body works harder to breathe due to airway obstruction
Asthma Triggers
- Virus infections: Colds or flu can trigger asthma symptoms
- Exercise: All forms of exercise, especially running, can trigger asthma
- Emotional factors and stress: Over-excitement and laughter can trigger symptoms; stress may worsen symptoms
- Atmospheric conditions: Changes in weather, especially cold, dry air, can trigger asthma
- Allergies: Allergies can be the most significant trigger for asthma, more than viral infections
Major Asthma Allergens
- House dust mites
- Feathers
- Animal fur or hair (dogs, cats, horses)
- Grass and tree pollens
- Mold spores
Asthma Causes
- Asthma is caused by airway narrowing
- Inflammation of the airway lining is the underlying problem
- Inflammation causes the airways to become irritable
Inflammation Effects on Airways
- Spasm: Inflammation causes the surrounding muscles to tighten
- Swelling: Inflammation causes airway lining to swell
- Excess mucus: Inflammation causes more sticky mucus production
Is Asthma a Virus?
- Asthma is not a virus
- It is a condition caused by airway inflammation
- Viruses are infectious agents that invade cells and cause illness, such as rhinoviruses
Is Asthma an Allergy?
- Asthma and allergy are not the same, but allergies can trigger asthma
- Allergy means sensitivity to substances that most people don't react to
