What are the symptoms of an allergy to gluten

Diarrhoea is the most common symptom of coeliac disease. It’s caused by the body not being capable to fully absorb nutrients (malabsorption, see below).

Malabsorption can also lead to stools (poo) containing abnormally high levels of fat (steatorrhoea). This can make them foul smelling, greasy and frothy.

They may also be hard to flush below the toilet.

Other common gut-related symptoms include:

And more general symptoms may include: 


If coeliac disease is not treated, not being capable to digest food in the normal way could cause you to become malnourished, leading to tiredness and a lack of energy.

Malnutrition in children can result in failure to grow at the expected rate, both in terms of height and weight.

Children may also own delayed puberty.

Gluten Sensitivity vs. Gluten Intolerance

Gluten sensitivity is sometimes mistakenly referred to as gluten intolerance. In 2012, top celiac disease researchers met in Oslo, Norway, to develop a standard way of speaking about celiac disease and other gluten-related disorders. There, researchers sure that gluten sensitivity, not gluten intolerance, is the most precise way to refer to the condition. To study more about the Oslo meeting and the current definitions for conditions related to celiac disease, visit our glossary.

Gluten Sensitivity

Part 3: Family and Related Conditions

Includes answers to:

  1. If I own non-celiac gluten sensitivity now, does that mean I would develop celiac disease if I continued to eat gluten?
  2. Does having a family member with celiac disease make you more susceptible to non-celiac gluten sensitivity?
  3. Are there any conditions that appear to be related to non-celiac gluten sensitivity?

Part 2: Testing and Diagnosis

Includes answers to:

  1. I’m already gluten-free and I feel much better than I did when eating gluten.

    Can I just assume that I own non-celiac gluten sensitivity?

  2. How can I get tested for non-celiac gluten sensitivity?
  3. Are there any dangers to a untrue diagnosis of non-celiac gluten sensitivity?

Part 4: Future Areas for Research

Includes answers to:

  1. We know that peripheral neuropathy can be associated with celiac disease.

    What are the symptoms of an allergy to gluten

    Is there a similar relationship between non-celiac gluten sensitivity and other neurological conditions?

  2. Does having non-celiac gluten sensitivity increase your risk of developing other autoimmune disorders?
  3. When will we know more about the long-term complications of non-celiac gluten sensitivity?

Symptoms of coeliac disease can range from mild to severe, and often come and go.

Mild cases may not cause any noticeable symptoms, and the condition is often only detected during testing for another condition.

Treatment is recommended even when symptoms are mild or non-existent, because complications can still occur.

Could it be FODMAPs?

The science on gluten sensitivity is evolving and we’re learning new information on the condition regularly.

New research suggests that gluten alone may not be responsible for the symptoms produced by the condition currently called gluten sensitivity.

Instead, it is showing that perhaps FODMAPs, a group of poorly digested carbohydrates, may be the cause of the symptoms instead. It is also significant to note that wheat, barley and rye — gluten-containing grains — are every high in FODMAPs.

Beyond Celiac encourages you to study about the low-FODMAP diet by downloading the free webinar, “Is Gluten Really the Problem? The Role of FODMAPs in Gluten-Related Disorders,” featuring Dr.

Dermatitis herpetiformis

Although not a symptom of coeliac disease, if you own an autoimmune response to gluten, you may develop a type of skin rash called dermatitis herpetiformis.

The rash is itchy and has blisters that burst when scratched. It generally occurs on your elbows, knees and buttocks, although it can appear anywhere on your body.

It’s estimated that around 1 in 5 people with coeliac disease also develop dermatitis herpetiformis.

The exact cause of dermatitis herpetiformis is not known, but, as with coeliac disease, it’s associated with gluten. Love coeliac disease, it should clear up after switching to a gluten-free diet.

Gluten intolerance is a wheat-related disorder. Symptoms, including stomach pain and bloating, happen after eating foods that contain gluten, such as, wheat, barley, and rye.

Researchers often call gluten intolerance non-celiac gluten sensitivity because, although celiac disease has similar symptoms, they are separate conditions.

In celiac disease, the body's immune system attacks its own tissues, triggered by gluten in the diet.

It only happens in people who own a genetic vulnerability. Scientists own identified certain genes that may be behind celiac disease.

However, gluten intolerance is less well understood and scientists are unsure why it occurs.

Fast facts on gluten intolerance

Here are some key points about gluten intolerance. More detail and supporting information is in the main article.

  1. Symptoms include bloating and stomach pain.
  2. Gluten intolerance is a wheat-related disorder.
  3. Diagnostic tests will law out celiac disease, while treatments focus on dietary adjustments.

Symptoms of gluten intolerance

Symptoms of gluten intolerance happen after the individual has consumed wheat.

The following checklist gives some signs to glance out for:

The following are less common symptoms of gluten intolerance:

  1. headache
  2. confusion
  3. anxiety
  4. stomach pain (more specific than stomach pain)
  5. numbness
  6. joint or muscle pain

It is significant to get medical advice for these symptoms to law out other causes. Gut symptoms can be vague and numerous conditions affecting the gut own overlapping symptoms.

Diagnosing gluten problems requires that the individual continues to eat gluten.

Diagnosis cannot be made if the patient decides to stop eating gluten before seeing a doctor.

Severe stomach pain is not a symptom of gluten intolerance. Severe pain requires immediate medical attention.
