Common food allergies in adults: what to know

Food Allergy can appear in adulthood even when a food was previously tolerated. Reactions may involve hives, lip swelling, an Itchy Throat, abdominal cramps, vomiting, wheeze, or dizziness. Symptoms that occur after a meal can also have non-allergic causes, so the timing and repeat pattern are useful but do not confirm the diagnosis.

Adults may notice reactions to nuts, shellfish, fish, milk, egg, wheat, soya, or particular ingredients in prepared foods. Alcohol, exercise, illness, or medicines may affect how a reaction unfolds in some people. Avoiding a food without guidance can make eating unnecessarily restrictive.

Note the food and ingredients, portion, preparation, time to symptoms, physical findings, and whether exercise or alcohol was involved. Keep packaging or a photograph of the label. Arrange a clinical review before challenging the suspected food at home. Allergy Testing can be considered when the history supports it.

Until assessed, avoid the suspected trigger and ask restaurants about ingredients and cross-contact. Discuss an individual emergency plan with a clinician, especially if a previous reaction involved breathing, widespread symptoms, or faintness.

Call emergency services for throat or tongue swelling, trouble breathing, faintness, confusion, or rapidly spreading symptoms after food. These can be signs of Anaphylaxis. Follow any prescribed emergency plan and obtain urgent care even if symptoms settle.

Ask whether your symptoms fit allergy or another reaction, which ingredients to avoid, whether testing or supervised assessment is appropriate, and how to handle accidental exposure. Ask for advice on nutrition if your suspected trigger is part of your regular diet.
