However, the symptoms that occur with FODMAP foods are not a marker of intolerance of these carbohydrates, but rather are a function of the breakdown of these foods in the setting of abnormal gut function. It is also important to note that IBS symptoms can occur after ingestion of any type of food, and are not limited to exposure to FODMAP foods.

Given these other reasons for GI sensitivity apart from the actual gluten protein, the syndrome termed non-celiac gluten sensitivity is likely not a true intolerance to gluten, but rather a form of IBS or other functional GI disorder.

Therefore, addressing the underlying pathophysiology of the functional GI symptoms can often be a more effective solution for GI sensitivity than eliminating foods either gluten or FODMAPs foods from the diet.

In fact, elimination diets or any other forms of restriction of food intake can sometimes make GI symptoms worse. Malnutrition can break down the intestinal lining and alter the gut microbiome normal gut bacteria leading to progressively worsening stomach and intestinal functioning.

A wide variety of nutrient intake, as well as adequate quantity of food, are essential for gut health. If gluten-free diets are not the answer, what else can be done to help GI sensitivity and Functional GI disorders?

In addition to adequate nutrition, probiotics and certain antibiotics can be useful to help realign the normal bowel bacterial flora, thereby decreasing bloating, pain and changes in bowel habits.

Dietary fiber or fiber supplements can be helpful for some individuals, and can also assist in maintaining the gut microbiome. In addition, targeting the gut-brain axis the signaling between the gut nervous system and the central nervous system , which has been shown to be dysregulated in the setting of IBS, can be very important for symptom improvement.

The gut-brain connection can be addressed through stress reduction, mindfulness and somatic-based therapy, as well as certain medications. Despite the common instinct to eliminate gluten products from the diet when abdominal pain, bloating and bowel changes occur, the science does not support this dietary restriction in individuals without celiac disease.

When GI symptoms occur with ingestion of gluten-containing or other foods, it can be helpful to address the underlying impairments in the GI tract rather than naming certain foods as the problem.

Our gastrointestinal tracts are designed to digest and utilize a wide variety of foods, though this complex system that is so crucial to our overall health and well-being sometimes needs some additional support to function smoothly.

This leads to inflammation. Zonulin is a protein that regulates the tight junctions of the small intestine. When zonulin is released in the intestines, the tight junctions open slightly and allow larger particles to pass through the intestinal wall 12 , Some studies have found that gluten activates zonulin, which leads to increased intestinal permeability 11 , 14 , One of these studies found that gluten activated zonulin in cells from individuals with and without celiac disease.

However, zonulin levels were much higher in cells from people with celiac disease Studies have consistently demonstrated that gluten significantly increases intestinal permeability in people with celiac disease 16 , 17 , There are mixed results when it comes to individuals without celiac disease.

One clinical study also found that gluten increased intestinal permeability in people with irritable bowel syndrome IBS However, in other human studies, gluten did not cause any changes to intestinal permeability in those with non-celiac gluten sensitivity or IBS 20 , However, it appears that gluten does not increase intestinal permeability in people without these health conditions.

Gluten activates zonulin and increases intestinal permeability in people with celiac disease. Gluten does not increase intestinal permeability in people without these health conditions. Medical professionals are still trying to understand exactly what causes leaky gut syndrome.

However, a few factors are known to contribute to the condition. Many factors contribute to the development of leaky gut syndrome. In people with celiac disease or IBS, gluten may be a contributing factor.

Often, people with coeliac disease will have no other family members who have been diagnosed with the condition, either in their immediate family or in other generations.

Coeliac disease should also be considered when these following risk factors or associated conditions are present:. As the symptoms of other conditions can closely mimic coeliac disease, it is important the diagnosis be confirmed to ensure appropriate treatment.

If the results are positive, your doctor will refer you to a gastroenterologist. This specialist will confirm the diagnosis by performing a gastroscopy — a procedure that allows tiny samples biopsies to be taken from your small intestine.

This procedure occurs while you are under sedation and involves a slender instrument an endoscope being passed through your mouth into your small intestine. Coeliac disease can be diagnosed without biopsy in some children if strict criteria are met.

Importantly, a diagnosis of coeliac disease should only be made by a gastroenterologist. Do not try to self-diagnose coeliac disease. These tests are dependent on a normal gluten intake.
