Study Notes

Asthma

Pathophysiology:
- Airway hyper-responsiveness: Airways become overly sensitive to triggers, causing constriction.
- Inflammation: Immune cells (eosinophils, mast cells, T-lymphocytes) cause inflammation, damaging airways and producing mucus.
- Airway remodeling: Chronic inflammation leads to permanent narrowing and thickening of the airways.

Etiology

Complex interplay of genetics and environmental factors: The exact cause is unknown, but genetics (family history) and environmental exposures (allergens, irritants, viral infections, occupational exposures, socioeconomic factors) play a role.

Epidemiology

Global health problem: A significant global concern affecting millions.
Variations in prevalence: Rates vary geographically, higher in developed countries and urban areas, with low-income populations also affected by socioeconomic factors.

Understanding Factors

Identifying at-risk populations: Understanding these factors helps in identification of at-risk groups and development of preventive strategies.

Prognosis

Lifelong condition, but manageable: Asthma is a chronic condition. Proper management and treatment can allow for a fulfilling life.
Early diagnosis and treatment crucial: Early diagnosis and treatment can help prevent complications like lung decline and hospitalization.
Importance of good asthma control: Well-controlled asthma improves quality of life and life expectancy.
