Patient's Query

Hi doctor,

I am a 30-year-old male. In the space of two weeks, I developed an allergic reaction to three different foods peanuts, shellfish, and avocado. I never had problems with either of these foods (or any food for that matter) before and this hit me very suddenly. So far the reactions are mild, just 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 into producing this allergic response.

My questions are: is it normal to develop an allergy to multiple foods simultaneously? And what can I do to prevent the onset of any further reactions from developing? I am currently on Memantine and Adderall.

Hi,

Welcome to icliniq.com.

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

Yes, it is common to have these kinds of food allergies. Some people have episodic allergies and they subside completely and for few people, it stays. No one can prevent an allergic episode in the future. It is your genetic system that has caused this.

You should always keep anti-allergic tablets, steroid tablets, and always have a back up to get a steroid shot for allergies. Because sometimes these might range from basic skin rashes, itching and flushing to life-threatening spasms. Hence should always be careful. When you consume the above foods next time, keep observing for symptoms.

I hope this helps.

Same symptoms don't mean you have the same problem. Consult a doctor now!
