Introduction

Asthma is characterized by episodic wheezing, shortness of breath, chest tightness, and coughing due to airway inflammation and hyperresponsiveness. While some individuals experience mild, intermittent symptoms, others suffer from severe, persistent disease. The multifactorial nature of asthma complicates its management and necessitates a comprehensive understanding of both environmental and genetic factors that influence its onset and progression [1].

Genetics play a critical role in asthma, with studies indicating that children of asthmatic parents are significantly more likely to develop the condition. Genome-wide association studies (GWAS) have identified several genes associated with asthma, including ORMDL3, IL-4, IL-13, and ADAM33. These genes are involved in immune system regulation, inflammatory pathways, and airway remodeling. Genetic predisposition often interacts with environmental exposures, amplifying asthma risk and severity [2].

Beyond inherited genes, epigenetic modifications—heritable changes in gene expression not caused by DNA sequence alterations—are increasingly recognized in asthma pathogenesis. Environmental exposures, such as tobacco smoke or air pollutants, can modify DNA methylation patterns and influence gene expression related to inflammation and immunity. These findings underscore the importance of a combined genetic-environmental approach to asthma research and prevention [3].

Exposure to allergens such as dust mites, mold spores, pet dander, and cockroach droppings is a major environmental trigger, especially in urban settings. Poor indoor air quality, often linked to inadequate ventilation, further exacerbates allergen sensitivity. Interventions such as the use of HEPA filters, removal of carpets, and moisture control can significantly reduce allergen exposure and improve asthma control, particularly in sensitized individuals [4].

Air pollutants, including ozone, nitrogen dioxide, and particulate matter, have been closely linked to asthma development and exacerbations. Urban environments and areas with heavy traffic expose residents to higher pollution levels, increasing asthma prevalence. In occupational settings, workers exposed to chemicals like isocyanates, formaldehyde, or flour dust may develop work-related asthma. Regulatory measures and protective equipment are critical in reducing risk in these populations [5].

Conclusion

Asthma is a dynamic disease influenced by a combination of genetic and environmental factors. A thorough understanding of these triggers is essential for both effective management and long-term prevention. By integrating genomic insights with environmental interventions and public health strategies, the burden of asthma can be significantly reduced—offering improved quality of life for millions of individuals worldwide.
