What Is A Gluten
Gluten-free diets have surged in popularity in recent years. Supermarkets devote whole aisles to products, and restaurants have entirely gluten-free options on the menu to cater for customers dietary requirements.
Gluten-free is one of the biggest revolutions in the food industry since vegetarianism. From gluten-free vodka to popcorn, there doesnt seem to be a food that isnt available free-from if you want it.
A diet of this nature consists of cutting out all foods that might be igniting the intolerance such as wheat, rye or barley which could appear as wholegrains or thickening agents in processed foods. Couscous, bulgur, spelt and matzo are also commonly removed from the diets of people with a gluten intolerance.
So How Do I Get Diagnosed
Non-celiac gluten sensitivity is diagnosed by process of exclusion. Experts recommend that you first get tested for a wheat allergy and for celiac disease. If both of those are negative, then your doctor may recommend a gluten elimination diet. If symptoms improve on a gluten-free diet, then you likely have non-celiac gluten sensitivity.
It is very important that a knowledgeable physician oversee this entire process, which can help to omit patients self-diagnosing themselves and to reduce the likelihood of a placebo effect occurring during dietary intervention.

Glutencheck Gluten Intolerance Test By Nanorepro
This is an at-home test for celiac disease that looks for antibodies related to the condition.
To take the test, a person needs to provide a blood sample via a finger prick. Next, a person mixes their sample with a solution and compares the color of the mixture with the shades on a color chart. Any changes in the color of the sample mixture can indicate that a reaction has occurred.
Unlike other tests, the GlutenCHECK test does not require a person to return their sample to a lab.
Understanding Specificity And Sensitivity In Blood Tests
Different conditions rely on tests with different degrees of specificity and sensitivity. These terms are important to understand:
Specificity is defined by what possible conditions can cause a positive result for a test. If only one single condition or disease can cause a positive result, than that test is considered 100% specific to that condition.
But if more than one condition might change the antibodies measured by the test, than it is not a 100% specific test.
Sensitivity is defined by how often a test identifies people with a condition. Some tests will only show a positive result for 90% of people who take the test. So that test would be considered 90% sensitive.
Unfortunately, it isnt very common for tests to be 100% specific and 100% sensitive. This is why most blood tests involve a combination of tests. Sometimes the result is determined by both a combination of tests and the doctors interpretation of your overall medical profile.

What Is This Pesky Protein Composite
Gluten is a protein composite we call it a composite because it actually contains several proteins found in the triticae family of grassy grains the most common and potent forms are found in wheat, barley and rye. It provides dough its unique elasticity and strength, and gives baked goods form and texture.
Even if you avoid these grains, this pesky protein composite is added to so many products that it can be very difficult to completely remove it from your diet.
To better understand gluten and to learn just how pervasive it is in the western diet, see the following lesson: What Is Gluten?
How Many Forms Of Gluten Intolerance Exist
This surprises some people , but there is more to gluten intolerance than celiac disease. While it is still considered the most serious medical condition among them, celiac disease is only one of several significant medical conditions triggered by the consumption of this troublesome protein composite.
- Celiac Disease
- Dermatitis Herpetiformis
- Gluten Ataxia
Along with gluten ataxia, a growing number of gluten-sensitive idiopathic neuropathies are being diagnosed. Collectively medical researchers now refer to these conditions as gluten-related disorders.
Unfortunately, each of these conditions require a different means for diagnosis and with two of them, NCGS and gluten ataxia, doctors and researchers havent yet agreed upon a consistent and accurate way to perform diagnosis.
In addition, one form of gluten intolerance, dermatitis herpetiformis, requires a skin biopsy, not blood work. Also, doctors and researchers havent yet agreed on how to identify a non-celiac gluten sensitivity in a consistent and accurate manner, other than to rely on a diagnosis by deduction.
In other words, if a gluten challenge reveals a problem with gluten but the patient tests negative for both celiac disease and a wheat allergy, then the patient will be diagnosed as non-celiac gluten sensitive .

Are Gluten Intolerance And Celiac Disease The Same Thing
Gluten intolerance and celiac disease are different. People with celiac disease have an autoimmune response to gluten. This means their bodies try to fight against gluten as if it were a virus. This reaction causes inflammation and damage to their digestive tracts. Celiac disease is the result of an abnormal gene. People with celiac disease also have high levels of certain antibodies in their blood, which are substances that fight gluten.
Gluten sensitivity and celiac disease cause a lot of the same symptoms. But people with gluten sensitivity dont have an abnormal gene or antibodies in their blood.

Diagnosing Celiac Disease & Gluten Sensitivity In Adults
NYU Langone gastroenterologistsdoctors that specialize in diseases of the digestive systemare experts in diagnosing celiac disease and gluten sensitivity. Celiac disease is an autoimmune disorder in which the immune system mistakenly attacks the digestive tract after a person consumes gluten, a protein found in wheat, rye, barley, and other foods and beverages. Some vitamins, medications, and personal care products such as lip balm contain gluten.
During digestion, food passes through the intestines, where nutrients are absorbed into the body. Most of this absorption occurs in the small intestine, where tiny finger-like projections along the small intestinal lining, called villi, sweep the nutrients from food into the bloodstream.
People with celiac disease, however, have a genetic susceptibility to recognize gluten differently. When someone with celiac disease eats food that contains gluten, it triggers the immune system to attack the small intestine. The body forms antibodies, or proteins, that attempt to remove gluten from the body as if it were a foreign invader. The antibodies also attack the lining of the small intestine, causing inflammation.
Over time, recurrent inflammation damages the villi in the small intestine, and the body doesnt absorb nutrients very well. This can lead to malnutrition and unwanted weight loss. The chronic inflammation also can cause abdominal discomfort.
New Study Confirms This Theory
A new Norwegian study published in Gastroenterology looked at 59 people who did not have celiac disease yet found digestive relief with a gluten-free diet .
Subjects were randomly assigned to eat seemingly identical muesli bars with either gluten, fructans, or neither for seven days.
They then crossed over into a different group, until they had completed all three bar diets and recorded their digestive symptoms.
Researchers found that symptoms of IBS, especially bloating, were 15% worse after eating the fructan muesli bar compared to placebo.
Interestingly, the gluten bar had no effect on symptoms, which suggests gluten is not the culprit after all.
Lead author Gry Skodje believes these findings strongly support the idea that fructans in wheat are the trigger of digestive symptoms, not gluten.
It also helps explain why researchers have been left stumped trying to figure out how gluten causes issues for non-celiacs.
Ideally, the next step would be a larger study that controls the participants outside food intake as well.
Summary: Research shows 4 in 5 people who believe they are sensitive to gluten are actually not. A new clinical trial suggests the likely cause of their digestive symptoms are fructans, which are also found in wheat.

Common Signs Of Gluten Intolerance
Those with gluten intolerance may manifest a wide range of symptoms. Some of them include digestive problems, such as bloating, abdominal pain, constipation, and diarrhea. Other signs that may occur include joint pain, fatigue, nausea, and headaches.
If you are gluten intolerant, symptoms may begin to show shortly after consuming a gluten-rich meal. However, some people may start experiencing the symptoms a day or so after eating gluten.
While having excessive gas could be a sign that you are intolerant to gluten, it could also be as a result of other health conditions. The truth is, gluten intolerance is not yet fully understood, but we know that making changes in what we eat helps a great deal. That is why you will have to follow a gluten-free diet to manage this condition and maintain your health.
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.

A Special Note About Celiac Disease Testing
One important note to remember: if you are concerned that you may have Celiac Disease, speak with your healthcare provider before introducing gluten into your diet. In the event that you do have Celiac disease, it can be hazardous to your health. Celiac Disease is covered in greater detail in this blog post.
Expanding On The Gluten Challenge
So, I have something to admit. I dont often give the Gluten Challenge to my clients. Thats because those with gluten sensitivity often have a sensitivity to other foods. In fact, once your immune system learns to treat gluten as an enemy, it often starts attacking other grain proteins too, such as corn, oats, and rice. Additionally, many people with gluten sensitivities also have diary sensitivities and other food sensitivities.
If you have multiple food intolerances, then taking the Gluten Challenge may not yield strong results. You may notice a slight improvement in symptoms due to the elimination of gluten, but if your immune system is still reacting to dairy and other grains, you may conclude that gluten isnt your problem.
When I suspect food sensitivities in a client, I like to put them on what is often known as an Elimination Diet. To be honest, I dont really like this name, because it implies deprivation instead of a diet designed to help you bring wellness back into your life.
The Elimination Diet works very much like the Gluten Challenge, but instead of just cutting gluten out of your diet, youll be cutting anything that could possibly cause an immune reaction. The diet is strict, but it still leaves room for healthy, nourishing, delicious meals. Trust me! Ive gone through it myself. It does help to work with a functional practitioner to guide you on what you can eat and what types of food you should avoid.

Genetic Testing For Celiac Disease
The most established genetic test is specific to celiac disease and not necessarily for a wheat allergy, a non-celiac gluten sensitivity or a broader intolerance. But it can help either verify the presence of celiac disease or identify people who may be predisposed to developing celiac disease. Because it can be done in a non-invasive manner , this celiac disease genetic test is often done for at-risk children.
The test looks for the HLA-DQ2 and HLA-DQ8 genes. If one or both genes are present and the patient has a family history of digestive concerns, the individual is at a greater risk of developing celiac disease at some point in his or her life.
Please note, however, that it is still possible to have these genes and not develop celiac disease. In fact, around 35% of the general population has these genes while around 1% of the population has celiac disease. That means millions of people have the so-called celiac gene but do not have celiac disease.
So this test is usually either to take preliminary steps in identifying and helping at-risk individuals or to help confirm a diagnosis begun with some of the tests listed earlier in this lesson.
How Is Coeliac Disease Managed
Coeliac disease can’t be cured, but it can be controlled with a strict, lifelong gluten free diet. Your sensitivity to gluten will never go away. The only way your small bowel can heal, and then stay healthy, is by removing all gluten from your diet, even if your symptoms are mild. Mild symptoms dont mean you have a mild disease.
You can expect to have a blood test at 6 months and 12 after you are diagnosed, and then yearly after that, to check if you have been exposed to gluten. Your doctor may also request another small bowel biopsy about 18 to 24 months after you are diagnosed to make sure your bowel is healing. You will also need a medical review every year.

Is There A Gluten Intolerance Test
If you often feel bloated or get constipation and stomach pain after eating, you should first be examined by your doctor before cutting things out of your diet or deciding to go gluten-free.
If you get the medical all-clear and think certain foods could be contributing to your symptoms, it is worth considering a food intolerance test. Food intolerance is characterised as a delayed onset food reaction and is estimated to affect 45% of the UK population.
Understanding your personal food and drink intolerances, or food fingerprint, can help you identify what your body is reacting to. A YorkTest Premium Food Intolerance Test can pinpoint precisely which foods are causing elevated levels of IgG antibodies in your blood, as it tests reactions to more than 200 ingredients and shows your degree of reaction through a traffic light system.
It is also important to get expert nutritional advice, so you can replace your trigger foods with balanced alternatives and maintain a healthy diet.
