An individual who is allergic to onions might end up with undesirable symptoms. If an individual is suspected with a food allergy, it is vital to determine the specific food so that the necessary steps can be taken.
If onions are suspected as the cause, an allergist should be consulted to confirm the allergy and start specific treatment options.
What are the indications?
The indications of an allergic reaction are the same as with any form of food allergy such as:
- Stomach cramps
- Inflamed, swollen or reddened skin
- Runny nose
- Itchy eyes
The signs of an allergic reaction might arise in just minutes of ingesting or direct exposure to onions. Nevertheless, some might not experience any symptoms until up to 2 hours after exposure.
Management of allergic reaction to onions
The ideal approach in managing an allergy to onions is to avoid them completely. Nevertheless, if exposure is unintentional or could not be avoided, an antihistamine medication or auto-injectable epinephrine might be beneficial.
Remember that onions are often added as one of the several ingredients in a dish and their presence might not always be evident. Those who are allergic should carefully read the labels before eating processed foods.
