Study Notes

Asthma Characteristics and Risk Factors

Asthma is characterized by recurring episodes of wheezing, coughing, chest tightness, and shortness of breath due to airflow obstruction and inflammation.
One of the characteristic features of asthma is reversible airflow obstruction.

Risk Factors for Asthma

Atopy, or the presence of allergies, is a risk factor for developing asthma.
Respiratory infections, such as the common cold, can trigger asthma attacks.
Exposure to air pollutants, like tobacco smoke and smoke from wood-burning stoves, increases the risk of developing asthma.
Obesity is a risk factor for asthma.

Symptoms of Asthma

Wheezing, or a high-pitched whistling sound while exhaling, is a common symptom of asthma.
Coughing, especially at night or during exercise, is a symptom of asthma.
Shortness of breath, or feeling like you can't catch your breath, is a symptom of asthma.
Chest tightness, or feeling like there's a belt around your chest, is a symptom of asthma.

Triggers of Asthma Attacks

Allergens, such as dust mites, mold, and pet dander, can trigger asthma attacks.
Irritants, like tobacco smoke and air pollution, can trigger asthma attacks.

Mechanisms of Asthma

Constriction of the airway muscles is a mechanism that can cause flow obstruction in asthma.
Inflammation of the airways is another mechanism that contributes to airflow obstruction in asthma.
