Most Common Gluten Intolerance Symptoms [Diet Recommendations]

Gluten is a protein richly found in cereals, such as wheat, barley, and rye. However, some people often show intolerance towards gluten and show reactions like bloating or pain after eating foods that contain gluten.

People often misunderstand the signs of gluten intolerance with celiac disease and end up taking the wrong medicines.

Thus, it’s important to have a clear understanding of the gluten intolerance meaning and its symptoms to differentiate it from celiac disease.

To help you with that, here we have a blog that clearly points out the gluten intolerance symptoms and other important information about the condition.

Gluten intolerance encompasses all the physical reactions in response to the entry of gluten into your body.

These reactions often show similarities to the symptoms of Celiac disease and wheat allergy.

However, celiac disease is an autoimmune disorder that affects your digestive tract. On the other hand, gluten intolerance doesn’t affect the gastrointestinal tract similarly!

Apart from this, wheat allergy which is often mixed up as gluten intolerance is a fatal condition as it often leads to impairment in breathing.

Altogether, gluten sensitivity symptoms are less severe as compared to those of celiac disease.

With the lines drawn among the three conditions, it’s easier to not mix up gluten intolerance with other conditions.

Moreover, in the subsequent sections, we will be outlining some of the major symptoms of gluten intolerance.

[8] Early Signs of Gluten Intolerance Or Gluten Allergy Symptoms

  1. Bloating
  2. Abdominal pain
  3. Sudden weight loss
  4. Headache
  5. Diarrhea and constipation
  6. Skin relates issues
  7. Fatigue

Like mentioned, signs of gluten intolerance are often confused with many other medical conditions like wheat allergy and celiac disease.

Thus, it’s imperative to have a clear idea about the symptoms of this condition to not confuse it with wheat intolerance symptoms or other such cases.

Hence, here are the 8 major signs of gluten allergy or gluten intolerance that will help you identify the condition.

Furthermore, it’ll help you be conscious about the condition you are going through and help you choose the right medicines and diet.

#1. Bloating 


Ever felt your stomach swelling up or felt as if your stomach was getting filled with gas?

Both conditions are called bloating which often makes a person feel miserable.

Though bloating is a common sign of many disorders, it’s also a major symptom of gluten intolerance.

In fact, if you ask us “what are the first signs of gluten intolerance”, the answer will include bloating as the most common complaint from people with gluten sensitivity.

Moreover, according to a prominent study, 87% of the people suffering from non-celiac gluten sensitivity show signs of bloating.

#2. Abdominal Pain

Abdominal pain can be a result of several disorders and diseases.

However, it’s also a common and one of the first signs of gluten intolerance.

Around 83% of the people suffering from gluten intolerance undergo abdominal pain and discomfort after eating foods rich in gluten.

#3. Weight Loss

Unexpected or sudden weight loss is often a matter of concern.

According to studies, unexplained weight loss is a major symptom in gluten intolerant people also suffering from celiac diseases.

In a prominent study, two-thirds of the celiac disease patients showed weight loss within six months.

Moreover, weight loss can also be a result of poor absorption of nutrients and other digestive problems.

With the signs and symptoms pretty clear, now you must be cautious about the foods you should eat and the foods that you should avoid.

Thus, here we have the next section focusing on the diet plan that you could follow for staying away from the signs of gluten intolerance.

#4. Headaches


Headaches and migraines are common in people once in a while.

Migraines are pretty common in people on the western side of the world with almost 10 to 12% of the people showing signs of migraines.

Do you know what’s even more interesting?

Studies show people suffering from gluten intolerance are prone to migraines as compared to others.

#5. Diarrhea, Constipation, and Odorous Feces

Occasional scenarios of diarrhea or constipation are very common. 

However, when you start seeing such episodes daily, there is something to worry about.

These regular cases are common signs of gluten allergy!

In cases of people suffering from celiac disease, eating gluten causes severe inflammation in the small intestine.

This leads to damage in the gut lining and causes poor absorption of nutrients and discomfort in your intestine, which consequently causes diarrhea.

However, gluten also causes problems in people who are not suffering from celiac.

According to a study, more than 50% of people suffering from signs of gluten intolerance showed signs of diarrhea, and 25% of them experience constipation.

Apart from this, people might also experience smelly stools because of poor absorption of nutrients.

The frequent cases of diarrhea might also cause severe diseases and health issues.

#6. Skin Related Issues

Gluten Intolerance has active effects on your skin.

In cases of people suffering from celiac diseases, gluten causes a blistering skin condition called dermatitis herpetiformis.

NOTE: All the individuals suffering from celiac disease are sensitive to gluten but less than 10% of them show digestive symptoms exhibiting celiac disease.

These are some skin-related diseases that have shown improvement while on a gluten-free diet:

  • Psoriasis – a disease that causes redness and scaliness of the skin
  • Alopecia Areata – an autoimmune disease that shows non-scarring hair loss
  • Chronic Urticaria – a condition where skin shows itchy, pink, or red lesions with pale centers.

#7. Tiredness

The feeling of tiredness is quite common and often not linked with any diseases.

However, the constant feeling of tiredness cannot be normal and might be an underlying result of some disease.

If we talk about the people suffering from gluten intolerance, they are quite prone to fatigue and tiredness, especially after eating gluten.

According to a study, 60 to 82% of gluten intolerant people show tiredness and fatigue.

Apart from this, gluten intolerance can also cause iron-deficiency anemia, which causes more tiredness and even loss of energy.

#8. Depression

Depression affects almost 6% of adults with its symptoms ranging from feelings of hopelessness and an inability to focus on anything.

People who have digestive issues often show anxiety and depression as compared to healthy individuals.

Moreover, these symptoms are also common in people who have celiac diseases and show gluten sensitivity.

Staying gluten-free is the best diet for depression if you’re gluten intolerant.

However, you must be wondering how gluten intolerance can cause depression.

Let us answer that for you by presenting you with the following theories that show how signs of gluten intolerance can include depression:

Abnormal Serotonin Levels

Serotonin is an active neurotransmitter that helps cells communicate with each other.

It is also called the happiness hormone, and when its level goes down, symptoms of depression are seen.

Gluten Exorphins

These are the peptides that are formed during the digestion of gluten proteins. 

These peptides often interfere with the nervous system and increase the risk of depression.

Gut Mycobacteria

The increase in harmful bacteria and reduction of the good bacteria affects the nervous system and increases the risk of depression.

Besides, there are many studies that claim that people with gluten intolerance who were earlier depressed felt better because of following a gluten-free diet. 

Plus, this also shows that exposure to gluten in gluten intolerant people encourages signs of depression.
