Gluten Oops...how Soon Will Symptoms Onset?

Recommended Posts

I'd like to know how long it takes for you to get symptoms when you accidentally consume some gluten. Specifically intestinal symptoms like bloating, gurgling stomach, and diarrhea. How many hours does it take from when you made the OOPS, until you noticed obvious symptoms? I'd like to get many different responses, because I'm curious to see how consistent (or inconsistent) the responses are.

Hi Tim, welcome :)

You will get lots of different responses since this is a pretty individual thing. For me, it usually takes about 2 hours for the bloating and gurgling to start. My second day is generally the worst of it.

I got glutened about 9:00 p.m. Diarrhea in the early hours of the morning and all next day, followed by gas and bloating for the next two days. This was my first food glutening; all the others have been meds and have only given bloating, gas and extreme nausea, no diarrhea. Don't know why the difference.

Hi and welcome!

I get a headache pretty quickly, but the GI stuff starts usually the next day. I don't really have gurgling or bloating, but my stomach and SI feel very inflammed, and when I eat it's 10x worse.

It takes me about 8-10 days to feel back to normal, but the first 3 days are the worst for me. After that, I feel like the inflammation subsides.

I've had different reactions.

Mostly, I am really gassy, have diarrhea for a few days, and am so bloated. I wore a pair of pants on a Wednesday, got cross contaminated on Thursday night, and wore the same pants on Friday afternoon and they didn't fit me. Fortunately they were side zip suit pants and the shirt and jacket I wore was long enough to cover the zipper being half up! My stomach also gets very noisy.

Once, I vomited about 4 hours after being glutened. I was completely fine the next day. I had no diarrhea. It was clearly not a stomach bug.

Hi and welcome!

I usually get my symptoms with in a couple of hours of consuming gluten. It is usually "D" and intense intestinal pain. I then have a headache the next day.

It's been a while since i got sick.... but I make all my own food, and never eat fast food or processed.

This sounds unbelievable, but I get symptoms within 5-15 minutes. I sometimes eat just a few bites and wait just a few minutes (if I'm eating out or food that I didn't cook myself) and then I can stop if it makes me ill. My immediate symptoms are burping, nausea, stomach noises (actually my stomach makes noises but feels like there's a wild animal inside it). Later symptoms are D for two days or so and mouth ulcers. I get mouth irritation the same day. I'm tired for a day or two.

I will start to feel it within about an hour - mostly nausea, headache or brain fog. An hour or so later, I get the gurgles and stomach pains, and sometimes a couple hours after that I get horrendous SHIVERING, but I am not cold (???). Nausea will continue for a good 12 hours, and the next morning - less than 24 hours - are the lower GI symptoms, not always D, but never comfortable.

I was accidentally glutened yesterday afternoon. I knew it right away because I get a sinus/migraine headache that will sometimes last for days (depending on how much is digested). About 1 hour later severe D, followed by hives/rash, nausea, mouth sores and then the next morning I get eczema all over my scalp and face. Fun stuff...

I have realized lately, that depending on what I consume, my symptoms will begin just not in the same order. It is all very strange.

my symptoms usually start within 15 minutes of eating something containing gluten. I get different symptoms every time. For example, the activia yogurt (yea, i didn't know it contained wheat in the natural flavors) made me look 6 months pregnant within 15 minutes and I got very dizzy and tired and cold. The next day I get diarrhea and the bloating/inflammation only subsides completely after 3-4 days. Also every food I eat during those 4 days doesn't go down quite well.

When I used to eat bread, I would get a headache within 15 minutes. Then dizziness, shivering, heavy feeling head, i fall asleep and when I wake up, I start bloating. The next few days is the bloating (again 3-4 days), gas etc.

I get neurological symptoms about an hour or two afterwards, sometimes sooner. I get "hot flashes", dizzy, and very, very sleepy. Headachey, too.

The digestive stuff doesn't kick in until the next morning, usually. And it takes a day or two. This is with amounts like you would find in Pringles (wheat starch) or things like that. I can't remember exactly the last time I ate a piece of bread, but I remember how horrible I felt almost immediately afterwards. I remember throwing up within an hour or two.

      I had the same thing happen to me at around your age, and to this day it's the most painful experience I've ever had. For me it was the right side of my head, above my ear, running from my nerves in my neck. For years before my outbreak I felt a tingling sensation shooting along the exact nerves that ended up exactly where the shingles blisters appeared. I highly recommend the two shot shingles vaccine as soon as your turn 50--I did this because I started to get the same tingling sensations in the same area, and after the vaccines I've never felt that again.  As you likely know, shingles is caused by chicken pox, which was once though of as one of those harmless childhood viruses that everyone should catch in the wild--little did they know that it can stay in your nervous system for your entire life, and cause major issues as you age.

      Thanks for the info. I recently moved to CA from Wyoming and in that western region the Costco and Sam's /Walmart Brands have many nuts and more products that are labeled gluten free. I was told it's because those products are packaged and processed  in different  plants. Some plants can be labeled  gluten free because the plant does not also package gluten products and they know that for example the trucks, containers equipment are not used to handle wheat, barely or Rye. The Walmart butter in the western region says gluten free but not here. Most of The Kirkland and Members Mark brands in CA say they are from Vietnam. That's not the case in Wyoming and Colorado. I've spoken to customer service at the stores here in California. They were not helpful. I check labels every time I go to the store. The stores where I am are a Sh*tshow. The Magalopoly grocery chain Vons/Safeway/Albertsons, etc. are the same. Fishers and Planters brands no longer say gluten free. It could be regional. There are nuts with sugar coatings and fruit and nut mixes at the big chains that are labeled gluten free but I don't want the fruit or sugar.  It's so difficult I am considering moving again. I thought it would be easier to find safe food in a more populated area. It's actually worse.  I was undiagnosed for most of my life but not because I didn't try to figure it out. So I have had all the complications possible. I don't have any spare organs left.  No a little gluten will hurt you. The autoimmune process continues to destroy your organs though you may not feel it. If you are getting a little all the time and as much as we try we probably all are and so the damage is happening. Now the FDA has pretty much abandoned celiacs. There are no requirements for labeling for common allergens on medications. All the generic drugs made outside the US are not regulated for common allergens and the FDA is taking the last gluten free porcine Thyroid med, NP Thyroid, off the market in 2026. I was being glutened by a generic levothyroxin. The insurance wouldn't pay for the gluten free brand any longer because the FDA took them all off their approved formulary. So now I am paying $147 out of pocket for NP Thyroid but shortly I will have no safe choice. Other people with allergies should be aware that these foreign generic pharmaceutical producers are using ground shellfish shell as pill coatings and anti-desicants. The FDA knows this but  now just waits for consumers to complain or die. The take over of Wholefoods by Amazon destroyed a very reliable source of good high quality food for people with allergies and for people who wanted good reliably organic food. Bezos thought  he could make a fortune off people who were paying alot for organic and allergen free food by substituting cheap brands from Thailand. He didn't understand who the customers were who were willing to pay more for that food and why. I went from spending hundreds to nothing because Bezo removed every single trusted brand that I was buying. Now they are closing Whole foods stores across the country. In CA, Mill Valley store (closed July 2025) and the National Blvd. store in West Los Angeles (closed October 2025). The Cupertino store will close.  In recent years I have learned to be careful and trust no one. I have been deleberately glutened in a restaurant that was my favorite (a new employee). The Chef owner was not in the kitchen that night. I've had  a metal scouring pad cut up over my food.The chain offered gluten free dishes but it only takes one crazy who thinks you're a problem as a food fadist. Good thing I always look. Good thing they didn't do that to food going to a child with a busy mom.  I give big tips and apologize for having to ask in restaurants but mental illness seem to be rampant. I've learn the hard way.          I don't buy any processed food that doesn't say gluten free.  I am a life long Catholic. I worked for the Church while at college. I don't go to Church anymore because the men at the top decided Jesus is gluten. The special hosts are gluten less not gluten free. No I can't drink wine after people with gluten in their mouth and a variety of deadly germs. I have been abandoned and excluded by my Church/Family.  Having nearly died several times, safe food is paramount. If your immune system collapses as mine did, you get sepsis. It can kill you very quickly. I spent 5 days unconscious and had to have my appendix and gall bladder removed because they were necrotic. I was 25. They didn't figure out I had celiac till I was 53. No one will take the time to tell you what can happen when your immune system gets overwhelmed from its constant fighting the gluten and just stops. It is miserable that our food is processed so carelessly. Our food in many aspects is not safe. And the merging of all the grocery chains has made it far worse. Its a disaster. Krogers also recently purchased Vitacost where I was getting the products I could no longer get at Whole Foods. Kroger is eliminating those products from Vitacost just a Bezos did from WF. I am looking for reliable and certified sources for nuts. I have lived the worst consequences of the disease and being exposed unknowingly and maliciously. Once I was diagnosed I learned way more than anyone should have to about the food industry.  I don't do gray areas. And now I dont eat out except very rarely.  I have not eaten fast food for 30 years before the celiac diagnosis. Gluten aside..... It's not food and it's not safe.  No one has got our backs. Sharing safe food sources is one thing we can do to try to be safe.

      Thank you kindly for your response. I have since gotten the other type of bloods done and am awaiting results.
