Is sudden food allergy possible without prior episodes?

Question

Hi doctor,

I am a 30-year-old male. In the past two weeks, I have developed an allergic reaction to three different foods: peanuts, shellfish, and avocado. I never had problems with these foods (or any food, for that matter) before, and this issue came on very suddenly. So far, the reactions have been mild, with only some minor tingling and flushing of the skin, particularly on my arms, but they are significant enough to be noticeable. I have always been into health and fitness and take a variety of vitamins and supplements, though I am cutting back on those out of concern that they may have aggravated my immune system and triggered this allergic response.

My questions are: Is it normal to develop an allergy to multiple foods simultaneously? And what can I do to prevent further reactions? I am currently on Memantine and Adderall (Amphetamine and Dextroamphetamine). No medications have been taken to resolve this issue except Benadryl (Diphenhydramine).

Kindly help.

Hi,

Welcome to icliniq.com.

First of all, allergic reactions to food are sudden and can occur without any prior history. It is very common for people to develop allergies.

Yes, it is common to develop food allergies. Some people experience episodic allergies that subside completely, while for others, the allergies persist. It is not possible to prevent an allergic episode in the future, as it is influenced by your genetic system.

You should always keep antihistamines and steroid tablets on hand and have access to a backup plan for getting a steroid shot if needed. Allergic reactions can range from basic skin rashes, itching, and flushing to life-threatening symptoms. Therefore, you should always be cautious and monitor for symptoms if you consume the foods in question again.

I hope this has helped you.

Thank you.
