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.
