10 Gluten Allergy Symptoms

Updated on November 20, 2017

Over the past decade or so, many more people have started to feel that they may be suffering from Gluten Allergy Symptoms. Why people develop a gluten allergy is still the subject of much debate with some people feeling it is strictly hereditary and others feeling there are more external factors involved, what we do know however is what the symptoms of a gluten allergy are and also how we can reduce these symptoms. Here are 10 gluten allergy symptoms to look out for if you think you might be suffering with this allergy.

Depression or Anxiety

Depression affects millions of people and most struggle to pinpoint the cause of their depression. There may be many different causes but have you considered the possibility that a gluten allergy or intolerance could be at the root of the problem? If you find that as you are reading the rest of this list quite a few of the symptoms seem to apply to you then perhaps gluten could be the culprit.


Heartburn can be called and related to many things, GERD and acid reflux being just a couple. While these may be the clinical names given to describe your problem with heartburn, have you ever wondered what might be causing it in the first place? If you are suffering with a Gluten allergy or intolerance then your ability to digest any foods containing gluten could well be hindered as your body rejects the food. This could lead to an increase in stomach acid or even a lack of stomach acid being produced depending on how your digestive system decides to deal with the undigested food, leading to many problems including heartburn and indigestion.


Again bloating is linked to improper digestion which could be caused by your body’s rejection of gluten. Many foods that contain carbohydrates also contain gluten. If carbohydrates don’t digest properly within the stomach they actually begin to ferment producing gases that can lead to bloating. So bloating could be another symptom of a gluten allergy.


If you are suffering from a gluten allergy then your immune system will effectively ‘fight’ any gluten introduced to your system and bloodstream. This can cause you to feel fatigued in the same way that you do when you become ill. Also if you are not digesting your carbohydrates properly then it stands to reason that this would also lead to fatigue.

Brain fog

Brain fog can come from many factors including the symptoms of a gluten allergy that we have already mentioned. Fatigue, improper digestion, and your own body’s immune system constantly working against you can all lead to brain fog.


Anaemia is a condition which leads to or is caused by a lack of red blood cells or haemoglobin in the blood. Many of you will have heard of Anaemia being linked with iron deficiency that can either be caused by a lack of iron in your diet or a lack of iron being absorbed from the digestive process. If your body is struggling to get the nutrients it needs from food because of impaired digest due to a gluten allergy, then Anaemia could well rear its ugly head as a symptom of this.

Abdominal pain

Similar to heartburn, acid reflux and bloating, a gluten allergy could cause quite severe abdominal and gastric pain.

Joint pain

Joint pain can arise from a gluten allergy for a couple of reasons. Firstly we have the problem we have already discussed of improper digestion and nutrient absorption. In the same way that your body may struggle to absorb enough iron, it may also struggle to absorb enough calcium needed to maintain bones and joints and any other nutrients needed to maintain cartilage etc. The second reason that a gluten allergy could lead to joint pain has to do with inflammation. As your immune system attacks any incoming gluten it can often cause inflammation to occur pretty much anywhere, including within joints.


Now might also be a good time to mention rashes then. Rashes are another sign that your immune system is fighting against something and causing inflammation as a result, this time of the skin. If your immune system is mistakenly classing gluten as an enemy then unexplained rashes could flag up as another symptom of a gluten allergy.

Diarrhoea and Constipation

Our final symptom of gluten allergy or intolerance is Diarrhoea or constipation. If the digestive process is impaired because of a gluten allergy then fibre digestion will likely be impaired too. Also your body might decide to slow or stop the digestive process to ‘protect’ you from the ‘invader’ (gluten) leading to constipation or it could decide to get rid of the ‘invader’ as soon as possible leading to diarrhoea.

So there we have it, 10 signs of a gluten allergy or intolerance. We’ll be discussing how to live with a gluten allergy in further articles so keep checking in when you have time.

      Like that, this article is really only the tip of the iceberg. It is a good starting point for most people. Getting checked out by a health professional, when you notice something is not right is the most important thing to do.

      Thanks TurtleDog & cleowolff and I hope it does help with your symptoms cleowolff. I would make sure that you are 100% sure in your decision before going completely gluten free though, as some people have huge issues if they try to reverse their decision at a later date finding that their symptoms are heightened when they reintroduce the Gluten. Perhaps you could try writing a food diary first to see if your symptoms coincide with gluten intake? Just something to consider.

      This is very informative. I have been debating switching over to gluten free foods for a while, but couldn't pinpoint any one cause of my symptoms. I do suffer from many of the symptoms listed in your hub and I think this may help me. Thanks!

      Thanks for the post. A lot of people go glut-free these days but I wasn't sure what the downside to gluten was for those who need to avoid it. Thanks for the great post. Voted up and interesting

      It's certainly a possibility Peg. Hopefully it could be something less life changing but if it does turn out to be a gluten allergy then at least there are steps you could take to reduce or even eliminate your symptoms.

      Interesting read here. Gluten Allergy? I've been wondering if this might be the root cause of some of my symptoms. It is incredible to find out that I have 9 out of the 10 you've described. Perhaps it's time for a trial of Gluten free food for me. Yikes.
