Allergy to onions: Signs, identification, management, and further information

In the world of food allergies, onion allergy is a relatively common condition that affects many individuals. This article aims to provide a clear and concise guide on the symptoms, diagnosis, and treatment options for those living with an onion allergy.

If you or someone you know experiences symptoms such as swelling, trouble breathing, itching, hives, or a tingling sensation in the mouth or throat, it is crucial to seek immediate emergency care. These symptoms may be indicative of an onion allergy, particularly when related to oral allergy syndrome caused by cross-reactivity with pollen allergens.

Onion allergy symptoms can vary greatly, ranging from mild oral discomfort to severe systemic reactions. In addition to the aforementioned symptoms, individuals may also experience watery eyes, swelling in the face or tongue, nausea, vomiting, abdominal pain, and breathing difficulties like wheezing and gasping. In extreme cases, severe allergic reactions or anaphylaxis can occur, involving chest tightness, dizziness, rapid heartbeat, or loss of consciousness.

Diagnosing an onion allergy typically involves a detailed history of symptoms related to onion intake, followed by skin prick tests or blood tests to detect specific IgE antibodies to onion proteins. In some cases, oral food challenges under medical supervision may be performed to confirm the allergy. It is essential to distinguish onion allergy from food intolerance or sensitivity, such as digestive symptoms caused by FODMAPs (fructans) in onions, as intolerance often causes digestive stress rather than immune-mediated allergic symptoms.

Once diagnosed, the primary treatment for an onion allergy is strict avoidance of onions and related allium plants like garlic. Carrying emergency medication such as antihistamines for mild reactions and epinephrine auto-injectors for those with a history of severe reactions or anaphylaxis is also crucial. Managing accidental exposures with prompt treatment, as advised by a healthcare provider, is essential. For some with oral allergy syndrome, cooking onions thoroughly may reduce allergenicity, but avoidance is generally safer.

It is important to note that there is no known cure for an onion allergy. People with an onion allergy may need to avoid foods with onion-derived ingredients, such as onion powder. If you think you have trouble digesting onions, it is advisable to discuss this with a doctor.

The Food and Drug Administration (FDA) requires food manufacturers to list the ingredients in their products, which can help avoid onions. The American College of Allergy, Asthma, and Immunology (ACAAI) recommends that people with food allergies wear a medical alert bracelet that lists their allergy triggers. The ACAAI also recommends that people at risk carry an epinephrine auto-injector device, such as an EpiPen, and should carry two in case of a severe allergic reaction.

Cross contamination or inhalation of onions can also trigger an allergic reaction. Therefore, it is essential for individuals with onion allergies to be vigilant about the foods they consume and the environments they are in.

In summary, onion allergy symptoms range from mild oral discomfort to severe systemic reactions. Diagnosis relies on clinical evaluation and allergy testing, and treatment primarily involves avoidance and readiness to manage allergic responses. For those living with an onion allergy, understanding the symptoms, diagnosis, and treatment options is crucial for maintaining a safe and healthy lifestyle.
