Epidemiology of Allergic Diseases

Epidemiology of allergic diseases studies how common these conditions are, who develops them, and why. Allergies, such as hay fever, asthma, or food allergies, are influenced by genetic, environmental, and lifestyle factors. Their prevalence varies worldwide, with increases seen in many regions, suggesting modern environments and lifestyle changes play a role. Factors like pollution, diet, and urban living can raise risk. Understanding these patterns helps identify causes, improve prevention, and develop better treatments, ultimately reducing the health burden caused by allergies across populations.
