What Are Nut Allergies?
Nut allergies are a type of food allergy characterised by an overreaction of the immune system to proteins found in certain nuts. For individuals with nut allergies, consuming or even coming into contact with nuts can trigger a range of symptoms, from mild to life-threatening. Nut allergies are common in the UK and affect both children and adults.
Types of Nut Allergies
Nut allergies can be broadly categorised into two types: peanut allergies and tree nut allergies. Peanut allergies are more prevalent and involve an allergic reaction to the proteins in peanuts, which are legumes. Tree nut allergies concern nuts like walnuts, almonds, hazelnuts, and cashews. It is possible to be allergic to one type of nut and not another.
Symptoms of Nut Allergies
Symptoms of nut allergies can vary widely between individuals. Common reactions include hives, swelling, stomach pain, and vomiting. Severe reactions can lead to anaphylaxis, a life-threatening condition that requires immediate medical attention. Anaphylaxis symptoms may include difficulty breathing, a rapid drop in blood pressure, and loss of consciousness.
Diagnosis and Management
Diagnosis of nut allergies typically involves a combination of medical history evaluation, skin prick tests, and blood tests to detect specific antibodies. The primary treatment is strict avoidance of nuts and nut-containing products. Those diagnosed with nut allergies are often prescribed an adrenaline auto-injector to be used in case of severe reactions. It is crucial to read food labels carefully and be mindful when dining out.
Living with Nut Allergies
Managing nut allergies in daily life involves vigilance and preparedness. Individuals should educate themselves and others about their allergy, wear medical identification, and have an emergency action plan. Schools, workplaces, and other public spaces in the UK are increasingly adopting nut-free policies to protect those with allergies. Support from healthcare providers and allergy support groups can also be beneficial.
