How long after eating gluten do you feel sick is one of those million dollar questions💰So let's get it answered - and quick. Because when you feel sick from gluten, you want relief STAT!
The time between when you eat and when you feel sick depends a lot on what's causing your reaction to gluten in the first place.
Gluten is a protein component of wheat and other grains like barley, rye and spelt.
Gluten can cause a whole bunch of reactions in sensitive people - everything from brain fog and bloating to skin problems and damage to the small intestine1.

🫢What's causing your symptoms after eating gluten?
As of now, there's 3 main disorders that involve being sensitive to gluten.
Each of these conditions fall under the category of "Gluten-Related Disorders".
- Non-Celiac Gluten Sensitivity (NCGS) - this term describes a condition where people have symptoms like bloating, nausea, stomach pain, brain fog and join pain. But these same people don't have celiac disease.
- Celiac Disease - is a condition that involves an immune-mediated response to gluten (the protein found in wheat, barely and rye.) If you need to go gluten-free for celiac disease, go here
- Wheat Allergy - is an immune reaction to foods containing wheat

Celiac disease and wheat allergy are fairly well established conditions.
And they pretty much have standardized ways of diagnosis and treatment.
Non-celiac gluten sensitivity on the other hand, is a relatively newer condition.
Even the name isn't 100% agreed on!
It's also been referred to as Non-Celiac Wheat Sensitivity (NCWS), Gluten Sensitivity (GS), or Gluten Intolerance (GI)
Researchers are still trying to figure out a safe and effective way to test for gluten sensitivity.
So as of right now, there's no 100% for sure way to know if you have gluten intolerance2.
The best you can do is cut out gluten for good.
Then track your symptoms and see if they go away.
See more about Non-Celiac Gluten Sensitivity and how to know if you have it.
📝What are the first signs of being gluten intolerant?
Non-celiac gluten sensitivity has been shown to cause symptoms that are related to the stomach or gut.
So you might have:
- Bloating
- Abdominal Pain
- Nausea
- Diarrhea
- Burping or "reflux"
But it's well-known now that gluten sensitivity also causes other symptoms that DON'T involve the stomach or gut.
They're ones like:
- Brain Fog
- Headache
- Fatigue
- Skin Problems
- Muscle & Joint Pain
- Depression
- Anemia

⏰How long after eating gluten will you feel sick?
So, how soon symptoms appear after eating gluten can depend on which of the 3 types of Gluten-Related Disorder you're dealing with.
- Gluten Intolerance (or non-celiac gluten sensitivity)
In the case of non-celiac gluten sensitivity, symptoms typically appear after a few hours or even days after eating gluten2.
For me, it's usually about 12 - 24 hours.
If I get super nauseated, bloated and have horrible stomach pain, I'll look back at my diet and try and figure out where some sneaky gluten got into my diet.
I also get brain fog and feel SUPER tired.
- Celiac Disease
In celiac disease, the time interval between eating gluten and the signs of intestinal damage can be long (up to weeks or years)2. Other symptoms can appear sooner, within minutes to hours.
With the damage to the intestine that occurs with celiac disease, it's so important that you remain completely gluten-free.
- Wheat Allergy
Typically with a wheat allergy, you’ll notice the start of symptoms pretty soon after eating gluten.
With a wheat allergy, symptoms typically appear within 2 hours of eating the gluten containing food and can start within minutes2.
If you live with a wheat allergy, talk with a trusted health care professional specializing in food allergies.
⏲️How long after going gluten free will you notice a difference?
Once you go completely gluten free, you should notice your symptoms get better in a few weeks.
But gluten sensitivity varies from person to person so it can depend on a few things.
For example, if you've been eating high amounts of gluten for years and just reduce the amount of gluten you have, you might not notice your symptoms go away completely.
Solution?
Make sure you go gluten-free for life.
If you cut most of the obvious sources of gluten out of your diet but are still getting small amounts in without realizing it, that can keep you from feeling your best.

The good news: being glutened can be prevented.
Going gluten-free will make sure that you don't feel sick from gluten ever again.
🤯What to do if you've been glutened
When you're in the middle of a gluten attack, try these tips:
- Move around if you can - when I would have a gluten attack, moving would be so hard. I could only lie in bed, curled up, clutching my stomach (sounds a bit dramatic but seriously, it was just so painful!) If I could manage to move around, it helped. A little bit. If you can walk - even if it's around your bed or up and down some stairs.
- If you're nauseated, you can try over-the-counter anti-nausea medication. My doctor suggested Gravol but it never touch the nauseated that I had from gluten bloating. Talk to your trusted healthcare professional for options for you.
- Go for a cleansing green smoothie that can have a natural anti-nausea effect. This green smoothie has ginger which for some people, helps digestion and can ease that sick feeling.

There’s not much info online regarding reintroducing gluten or how to do it.
Regarding symptoms it’s confusing to think you can feel off within hours to days. Is there a cut off point like past 3 days after consuming gluten and no symptoms then you’re out of the woods? Some sites say hours to weeks and I’m so confused how I’m supposed to know whether I can tolerate gluten if this is the case.
I ate gluten for 2 days just like one item a day. Then 2 days without and I felt sick on day 4. Now I’m unsure if it was related to gluten or not. I’m very confused as nothing is specific 🙁

Hi Michelle,
Thanks for commenting. You're right, it's so confusing. The best way right now to help figure out if it's gluten that could be causing a problem for you is to cut it out for 2 weeks and only then, reintroduce it. (I have a sample gluten-free meal plan on the site if you want to check that out.) But "clearing the slate", so to speak, and getting all remnants of gluten out of your body can help figure out what's going on.

Hey guys I'm waiting for a blood test as my symptoms have got worse. I had a packet of crisps 3 days ago and have had a bad stomach for days, how long does the bad stomach typically last as its effecting my sleep and my eating.
April says
Hey Phil,
Ouch, sorry to hear about the bad stomach. It could be the crisps but it could also be something else that you're eating if you're quite sensitive to gluten. Be sure you've cut everything out that even has very small amounts of gluten.
