Can you suddenly become allergic to nuts?

[Greenplant7]

I have no allergies but had an operation a couple of weeks ago and every time I eat nuts since my lips start to tingle. Is this just a random coincidence or have I developed a nut allergy?

My friend developed a severe seafood allergy from nowhere, so I'd imagine that it's possible for the same thing to happen with nuts. Hopefully yours won't get worse. Perhaps chat with your GP?

Yes, you can suddenly develop allergies out of nowhere. My grown up chef son developed a severe allergy to finned fish when he was about 20. Which was a shame as he always adored fish.

Thanks both, will book a doctors appointment x

Yes my friend did as a teenager after a serious illness, no allergies prior and after anaphylactic to nuts

Yes my friend developed quite a serious nut allergy at about 35! She now has to carry an epi pen.

Yes you can!

Yes,you can at any time. There have been reports of allergies developing after covid, and after pregnancy or other hormonal shifts is another common tkme.
Definitely discuss with your GP and maybe start carrying a packet of antihistamines with you in case you have hives or lip swelling

Absolutely. Anyone can develop an allergy to anything at any time, even if they’ve previously been exposed to the allergen. Your risk of developing an allergy is higher if you don’t have regular exposure to an allergen though.

Since my DS was diagnosed with a severe nut and peanut allergy we have fewer nuts in the house. I then had a reaction to pistachio twice in a row and realised it may have been two or three years since I’d eaten them. As I’ve had the reaction twice i now avoid pistachio, which is a shame as it’s a delicious flavour.

Yes, a friend developed a serious wheat allergy in their 30s. Came out of nowhere.

Yep. I could eat as many peanuts (not a nut, I know, but any food allergies in general included for context) as I liked til I was 22. Used to scoff them and love snickers, peanut butter and satay.

Then one day 💥 boom

Ten years without peanuts

Very sad :(

Yep. I suddenly became allergic to chilli🌶 when I was about 25.
Bloody annoying as I love spicy food.
At first my lips tingled, the swelled up, like I had bad lip fillers.
Them my face completely swelled up, to the point I couldn't see, as my eye lids covered my eyes.
I ended up in a&e because I started to not be able to breathe.

I asked the same question and the doctor explained you can develop allergies from nowhere.

Yes. Allergies can come and go randomly. My brother used to be able to eat apples but can’t due to the itching and swelling. I used to be allergic to avocados but lm not now. My peanut allergy is long term and l can’t see that changing now

Yup.

You can only be allergic to something you've previously been exposed to but it can happen at any time, from second exposure to 1000th, and at any age.

Yes. I have allergies since I had Covid. X

Thanks for your stories, very useful to know. Thought I was going nuts and imagining it (terrible pun apologies)
