Beyond people with celiac disease, the gluten-free diet has also been shown to potentially help treat a wide range of health conditions like inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), skin conditions, auto-immune diseases, and non-celiac gluten sensitivity. Symptoms can be similar among these health conditions, making it hard to determine the cause and seek treatment. 

What Is Gluten Intolerance?

Gluten is a protein commonly found in grains like wheat, barley, and rye. 

People with gluten intolerance, or non-celiac gluten sensitivity, typically have IBS-like symptoms such as bloating, stomach pain, fatigue, rash, and discomfort when consuming gluten. 

Some research indicates that it may only be wheat-containing foods or certain types of gluten-containing foods that trigger symptoms. 

Gluten intolerance can exhibit differently for each person, making it confusing and complicated to manage. 

Some people find they have to avoid all forms of gluten, others can avoid wheat forms of gluten, and still others struggle with gluten and fructans (a type of carbohydrate found in some fruits, vegetables, cereals, and grains).

Gluten Intolerance vs. Celiac Disease

Gluten intolerance is different from celiac disease but has some similarities.

People with gluten intolerance usually don’t have extensive intestinal damage, malabsorption, or antibody formation as with celiac disease. However, they may experience unpleasant gastrointestinal (GI) symptoms after eating gluten. Gluten intolerance is harder to diagnose due to the lack of accurate tests. 

Celiac disease affects about 1% of the population. It is often diagnosed through an intestinal biopsy and blood tests, but other tests may also be used. Diagnosis requires a life-long gluten-free diet to reverse the inflammatory process in the small intestines. 

Individuals with celiac disease have observable intestine damage, leading to complications like malabsorption, diarrhea, constipation, nausea, vomiting, and bloating. Malabsorption can lead to vitamin and mineral deficiencies, causing osteoporosis, anemia, and stunted growth.

Both conditions improve by following a gluten-free diet. 

Can I Have Gluten Intolerance Without Knowing?

You could have gluten intolerance without knowing. Many digestive health conditions can result in similar signs and symptoms, making it difficult to isolate the cause.

Common Signs And Symptoms

Signs and symptoms can vary between people but generally include the following after consuming gluten:

  • Bloating.
  • Stomach pain.
  • Fatigue.
  • Rash.
  • Discomfort.
  • Cognitive impairment (brain fog, problems with memory, attention, mental speed, and multi-tasking).
  • Depression.
  • Diarrhea.
  • Constipation (fewer than three bowel movements weekly).
  • Headaches.
  • Bone or joint pain.

Getting a diagnosis for your signs and symptoms can help you take proactive steps to optimize your health and prevent side effects and possible complications. 

Am I Gluten Intolerant Quiz: 7 Questions

Take this seven-question gluten intolerant quiz to determine if you have gluten issues. Discuss your responses with your healthcare provider for diagnosis and treatment options. 

This quiz is not intended to replace a medical diagnosis and is not a validated tool for diagnosing gluten intolerance.

1. Do I experience digestive issues after eating foods containing gluten?

Digestive issues often include bloating, nausea, vomiting, diarrhea, constipation, and stomach pain. These digestive issues after consuming foods containing gluten could indicate gluten intolerance. 

Other GI health conditions, such as IBS and inflammatory bowel disease, can also cause similar digestive issues which is why it’s important to be assessed. 

2. Have I been diagnosed with an autoimmune disorder or thyroid condition?

People with the following health conditions are often more likely to be intolerant to gluten: Hashimoto’s disease (autoimmune thyroid condition), type 1 diabetes, and rheumatoid arthritis

Additionally, these health conditions often coexist. Twenty percent of people with celiac disease have Hashimoto’s disease, and 17% of people with type 1 diabetes have Hashimoto’s disease. 

People with type 1 diabetes and celiac disease share similar genetic backgrounds that predispose them to both conditions. Around 4 to 5% of people with type 1 diabetes also have celiac disease. 

With rheumatoid arthritis, gluten may have an inflammatory effect on the digestive system. 

3. Do I feel fatigued or lethargic after consuming gluten?

Individuals with celiac disease or non-celiac gluten sensitivity often report feeling fatigued if consuming gluten

After twelve months of following a gluten-free diet, individuals with celiac disease reported a significant reduction in the prevalence and severity of their fatigue. 

4. Have I noticed skin changes or rashes after eating gluten?

Itchy skin, along with blisters, is a type of skin rash called dermatitis herpetiformis that occurs after eating gluten for individuals with celiac disease or gluten intolerance. 

After following a gluten-free diet, most individuals with this uncomfortable side effect were able to reduce or stop their medications to treat dermatitis herpetiformis. 

Skin changes and rashes are common side effects of various food allergies and intolerances; seeking a correct diagnosis from an allergist or immunologist can help find ways to alleviate your symptoms. 

5. Do I have a family history of celiac disease or non-celiac gluten sensitivity?

Celiac disease development involves genetics and environment, leading to an inappropriate immune attack on the intestines after consuming gluten. 

Research shows a strong genetic component for developing celiac disease. 

Additionally, a family history of non-celiac gluten sensitivity could indicate an increased risk, as similar genetic patterns were found between several autoimmune health conditions.

6. Am I trying to lose weight without success despite following a healthy diet?

Weight loss is more common with gluten intolerance and celiac disease due to the damage to the intestines and reduced absorption. 

However, weight gain can occur due to increased inflammation caused by consuming gluten, which the body considers harmful. Gluten intolerance can trigger gut dysbiosis and inflammation

Whenever weight changes occur that don’t make sense, it’s wise to seek support with pinpointing the cause.

7. Do I feel bloated after eating gluten?

Bloating or gas build-up in the digestive tract is uncomfortable and even painful. 

Bloating can be a common sign of abnormal digestion reported among people with gluten intolerance. 

If you experience bloating regularly after consuming foods with gluten, you might be intolerant. Tracking foods that trigger symptoms is helpful in developing an action plan with a dietitian.
