About this course

Food allergy arises from an adverse immunological reaction to food which may result in a life-threatening condition known as anaphylaxis. With its increasing prevalence, prevention and prompt diagnosis of this condition has become a public health issue. Many patients are first diagnosed with an immune response to food in the primary care setting. The presentation of patients suffering from food allergens can vary widely. Therefore, it is essential for primary care physicians (PCPs) to appropriately assess patients with food allergies.

Crucial in the diagnosis of food allergies is a detailed history and review of symptoms. In some cases, obtaining a good clinical history and physical examination will suffice. However, there are circumstances which would warrant further evaluation and testing. PCPs should be aware of the available tests or procedures that aid in diagnosing food allergies. This is to ensure that a proper and timely referral to a specialist is initiated.

Avoidance of food that triggers allergic reactions remains the primary management strategy in addressing food allergies. Nevertheless, it is important for caregivers and patients to have emergency action plans during accidental exposures to suspected allergens. PCPs should educate caregivers and patients on what to expect and how to manage such instances.

Food allergen immunotherapy is a novel approach which desensitizes patients to specific food allergens, leading to long-term tolerance. The available food allergen immunotherapies are administered by specialists. The PCPs’ role in these treatment advances is to appropriately explain its mechanism to caregivers and patients for referral.

This e-learning module provides an overview and practical approach to food allergies. The module will focus on its appropriate diagnosis and management in the primary care setting.
