Even though the exact allergen tends to vary, allergic reactions to various foods can be similar. It is important to note that all food allergies including onion allergy can trigger similar symptoms and usually treated with lifestyle changes or medications. Nevertheless, it is vital to know the specific foods that trigger the allergic response so that the appropriate first aid measures can be provided during a reaction. Steps must also be taken by the individual to avoid exposure to the food. Individuals who believe that they have an onion allergy must consult a doctor for validation of the allergy as well as discuss available treatment options. The testing for the exact allergen involves a skin prick test or blood tests. Both tests can help determine the exact allergen that initiates an allergic response.
What are the symptoms?
The symptoms of onion allergy are similar to any other food allergy. The usual symptoms include diarrhea, nausea, vomiting, hives, abdominal cramps, redness or inflammation of the skin and swelling. In some cases, others can experience runny nose or itchy eyes.
Take note that the symptoms of onion allergy typically manifest within minutes after eating onion or being directly exposed due to handling. Nevertheless, some do not experience any symptoms until two hours after an exposure.
Treatment for onion allergy
The ideal way to treat an onion allergy is to instruct the individual to completely avoid onions. In case of accidental exposure to onion or an exposure could not be avoided, you can provide antihistamine medications to provide relief to the upsetting symptoms. In severe cases, an injectable epinephrine or oftentimes referred to as EpiPen can be useful. Those who are sensitive to onions must take time in exploring all the available treatment options with a doctor.
Important considerations to bear in mind
An individual who has a food allergy must be careful with what he/she eats, especially those with onion allergy. It is a known fact that onions are often used as an ingredient in various dishes and their presence in a particular dish is not always apparent. Individuals who are allergic to onions must always read the labels of food carefully before eating processed foods. When eating outside, ask the server if a particular dish is free from onions. Preparing meals at home is a better way to minimize the risk of exposure to onions.
It is important to note that onions are not considered as a usual food allergen but it does not mean that it is not dangerous to those who have onion allergy. In some cases, an individual can develop anaphylaxis which can be lethal if not treated right away. The symptoms of anaphylaxis tend to vary but usually include difficulty breathing, abrupt swelling, rapid heart rate, lightheadedness, dizziness, confusion and loss of consciousness. An individual who is experiencing this type of reaction requires immediate emergency care.
