Potential oat intolerance

[ConsternationStation]

For the last year, since I had a tooth extraction, I've eaten porridge/oatmeal for breakfast, with a few exceptions. About a month ago, I noticed that despite waking up feeling fine I was feeling sick after breakfast and the nausea would last most of the day. Stomach would ache a bit too but nothing awful. A couple of weeks ago, I also started to feel body aches and fatigue alongside nausea. I largely put it down to stress and hormones as I had a lot on my plate.

Last week we went on holiday and I didn't touch oats for a whole week. No porridge, no oat milk, nothing. And I felt completely fine, no nausea, no aches. Came home yesterday, had porridge this morning and I'm so achy, nauseous and tired. My stomach has been cramping too. I feel pretty rotten.

Could I have developed an oat intolerance? Dr Google (I know I know) says all the symptoms could be. I think I'm going to eliminate oats from my diet and see if it improves. If I choose to try to reintroduce them (I love oat milk in my tea!) how do I do that?

I can’t have oats. It has gotten worse as I have gotten older. At this point the tiniest trace triggers vomiting and a multi day migraine.

The fact that they are used as a cheap filler and everything is now “multigrain” is a source of endless frustration. Every label has to be checked.

I don’t know about developing one but all my life oats had made me have those exact symptoms (even the fatigue, it’s so weird!) you describe, I didn’t think that much of it except thinking it was weird as everyone always said oats gave you loads of energy.

then I had DS2 who was diagnosed with oat allergy. His symptoms became really obvious after eating oat yogurt/milk. We’re both ok with a bit of cooked oat, like a hobnob, tiny amount of granola or something but avoid porridge, and definitely milk and yogurt. Obviously not life threatening but not very pleasant.

This is so true. There’s a coffee shop near me which serves only oat milk and doesn’t make it clear! Seems really irresponsible when it’s a known allergen wthat has ne be listed in bold on ingredient lists

I made the switch to oat milk about a decade ago after finding cows milk wasn't agreeing with me as much any more so to now have the same issue with oats (albeit worse!) is so frustrating. Weirdly, I can tolerate lactose again now so maybe I just have to make the switch back. Not thrilled.

I'm coeliac and was told not to eat oats, wheat , rye or barley. Even the gluten free oats affect me
