Food allergies have become a major public health issue, with rising global prevalence and significant impact on quality of life and healthcare systems. This thesis examines the complex causes of food allergies, including immune system dysfunction, environmental factors, and genetic predisposition. Management combines prevention and treatment strategies, such as medications, immunotherapy, and emerging biologic therapies. While drugs like antihistamines, corticosteroids, and epinephrine manage acute symptoms, long-term care focuses on immunotherapy and targeted immune treatments. However, challenges like treatment adherence, access, and varied individual responses persist. A multidisciplinary, personalized approach is crucial to reducing the burden of food allergies and improving outcomes.
