Final answer:
Asthma is a chronic respiratory condition that can develop at any age but often starts in childhood. Its epidemiology indicates a significant and increasing impact on global health, influenced by genetic, environmental, and psychological factors. Asthma attacks can be triggered by allergens, pollutants, and stress.
Step-by-step explanation:
Asthma is a chronic respiratory disease characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, chest tightness, and coughing. The epidemiology of asthma reflects its widespread impact, affecting millions of individuals worldwide. Environmental and psychological triggers, like pollutants and stress, can exacerbate asthma symptoms.
Asthma can onset at any age, but it often begins in childhood. Factors that predict the onset of asthma include genetic predisposition, obesity, sleep apnoea, and exposure to allergens and irritants. Stressful life events and familial conflicts have also been linked to the increased risk of developing asthma.
Common triggers of asthma attacks include environmental allergens, such as dust, pet dander, and pollen, as well as air pollution and smoke. Psychological factors like stress can also trigger asthma symptoms. Managing these risk factors is crucial for individuals with asthma to avoid exacerbation of their condition.
