My story. Wondering whether antibiotics could have caused my allergy.

I developed a severe allergy to tree nuts my freshman year of high school. I wasn't allergic to any foods during childhood and didn't really recognize what people with food allergies endured until I developed one myself.

Now I carry an epipen with me everywhere I go, because of the possibility of anaphylaxis. I haven't eaten tree nuts in years, even though I know how healthy they are, and this has really worked against some dietary changes I've tried to make over the years such as eating less animal protein and trying to eat more healthy plant-based fats and proteins, many of which are in nuts. I can eat peanuts but not any tree nuts.

I've always wondered why the allergy came about so late, where did the allergy come from? An article I read recently suggests it may be due to prescription antibiotic use. This makes sense, since I was prescribed antibiotics for a long time in middle school to fight against acne.

I found the publication and also an easier to understand article describing the publication.


Please consider checking these out and sharing any articles you've found. I really wonder if this is the case. I'd appreciate your thoughts.

    I developed peanut allergy, treenut allergy, also multiple fruit allergies all at around age 15 after having a major intestinal surgery for ulcerative colitis. 

    I have heard antibuotics can disrupt gut health and healthy bacteria often help us digest foods. 

    I do worse with sulfa antibiotics even now. My antibiotic of choice now is azithromiacin as it dusrupts my system less (and I have a very sensitive system).

    I think I became allergic to certain foods for a reason… The fruits I am allergic to are all on the dirty dizen list for high pesticide use, so when my system was recovering from surgery and introduced to these foids, it started develiping an allergy to them. Peanuts and peanutbutter can have higher molds and salmonella risks. Im not sure about treenuts besides that I think many of them cross-react with many environmental allergies like oral food syndrome, and can further develop into a true allergy. I think true allergies are formed after the body is harmed by a certain food or food-bourne illness and remembers it and basicalky targets the immune system against that food. 

    Many things that are considered health food to some people I am severely allergic to, so I know it is frustrating. I just remember to listen to MY allergies and reactions, and modify recipes accordingly. And try to eat at restaurants with food allergy menus. 

    My son has food allergies (nuts, soy, honeydew melon, cantaloupe) .. And environmentals (cat and dog dander, dust, pollens, molds,) He is 7 now and has only had antibiotics twice in his life for short times and had signs of allergy and tests prior to that. 

    I think antibiotics may play a role but that it is more complex than that. I think peopme with digestive problems and skin problems are at higher risk for allergy because they are more sensitive and open to things that completely healthy people might have a barrier against. I think if you need antibiotics that doctors should also prescribe good probiotics but since they dont– getting them from health food stores might help.

    But those are just my theories… I too was curious about hiw these allergies started and have to be careful and carry epipens.

    Wow, thank you for sharing your story and ideas. They are very interesting and sound like my experience in a lot of ways. I hope that you and your son are doing well.

    Hi, Arne … saw your other topic and replied to that, but I wanted to reply here as well. Hugs on developing a severe food allergy in high school! It sounds like you are taking all the right steps?

    Food allergies can develop at any age, according to my doctor, and the research is still ongoing as to why some people develop an allergy later in life.

    I developed an allergy to celery after I was 30, and I have an acquaintance who had eaten peanuts all her life until her 40s and then suddenly developed a major life-threatening allergy to peanuts.

    Neither of us had more than typical use of antibiotics. I have followed my doctor's advice about using antibiotics only when absolutely needed because I worry about antibiotic overuse and what it could mean for antibiotic resistance.

    Did you frequently eat tree nuts before your freshman year of high school? Or were tree nuts something you rarely ate?
