I'm new here, 15 year old daughter just developing symptoms?

Publish date:

Hi to everyone,

I was looking for a forum where I could get some good first-hand experiences and information when I found you all. Hopefully someone can help me out!

My daughter will be 15 in a couple of months. About a year ago ago, I took her to an allergist for the first time because she had (within the past 3 years) developed some seasonal allergies that were getting progressively worse. In addition, she had had a recent episode involving raw carrots where her lips swelled up and she ended up with two black eyes the next day. We realized (and it was confirmed by the allergist), that she had Oral Allergy Syndrome, which is a cross-reactivity to certain mostly raw foods where the proteins in those foods closely resemble the proteins in the pollen of the trees to which she is allergic.

Cutting out a lot of other details, she was discovered by the allergist to have an allergy to various types of pollen, soy (which is interesting because she drank a small amount of soy milk at a friend's house and had a very bad stomach ache for a few hours), an allergy to the foods associated with Oral Allergy Syndrome, and curiously, she had a small allergy to peanuts.

She has eaten and enjoyed peanuts and peanut butter her whole life, as has the rest of the family. We have never had a problem. I never restricted peanuts while I was pregnant or when she was little (as in, I ate it around her) and when she was about 1 or 2, she also began having peanut butter. She has never, and I mean never, had a reaction that I can ever remember. So we were really confused by the peanut reaction on the allergy testing.

So just recently she told me that the last 2-3 times I have sent her peanut butter in her lunch, she began having an itchy throat. Each of those times it got progressively more itchy. Obviously there wasn't a severe reaction, but it made me really nervous to hear this.

My questions to you are, have any of you heard of a child developing an allergy to peanuts in her teen years, and if so, is it worrisome that her throat is itchy? Meaning, would I have to worry about the itchiness becoming something more severe? And lastly, has anyone here had a severe reaction to peanuts that started just as an itchy throat?

This is really hard because in addition to these allergy issues (the OAS includes many good, healthy foods), she is a vegetarian, so peanut butter has been a good source of protein and minerals for her, and she also has acid reflux/GERD symptoms. The poor girl has to contemplate and time just about everything that goes into her mouth. It's really posing a lot of challenges.

Thanks for your help,


PS: We are definitely going to be reevaluated by the allergist now that she has the itchy throat.

that is horrible, I'm so sorry you are going through this. I don't understand why these peanut allergies keep showing up more and more. It sounds like hers is getting worse, I think they would prescribe her an epi-pen. Glad you are going back to get that re-evaluated. I don't know about the other stuff, but I hear more and more of older kids and even adults developing these allergies.

I believe you can develop allergies at any age. I've known a few adults who developed seafood allergies just out of nowhere. You mentioned your daughter has Oral Allergy Syndrome. Did you know that there has been some studies about OAS and peanuts. It appears that one of the proteins in a peanut is very similar to those of birch pollen. People with birch pollen allergies cross react with peanuts. One study suggested that 2 out 3 peanut allergies are misdiagnosed and that the individual actually has a birch pollen allergy. There are tests that can determine which protein in the peanut the individual is actually allergic to and whether it is the protein that is the same as birch or not. Allergen component testing is widely available in Europe, but not sure how available it is in the US. I just recently started researching this.

I have heard recently that you can develop a food allergy at any age. But because your daughter has Oral allergy syndrome I would check in with the allergist. The prev poster mentioned a test to determine the exact protien that is causing the reaction. Sounds like that would be worth looking into. Good luck
