What Is Gluten Intolerance Or Gluten Sensitivity Understanding How They Differ From Other Gluten
These two terms sound like theyre entirely different things, but actually theyre the same. We call these non-celiac gluten sensitivity, or NCGS, says Mukherjee. These are patients who have neither celiac nor wheat allergy, she says.
Testing wont show that youre producing antibodies or have inflammation in your small intestine. Still, symptoms can be very similar to celiac including bloating, gas, brain fog, abdominal pain, and changes in bowel movements, fluctuating from diarrhea to constipation, joint pain, muscle cramps, neuropathy and they tend to improve when a patient stops eating gluten. Mukherjee adds that these symptoms are often very similar to what people with irritable bowel syndrome experience.
That said, theres no test to definitively diagnose someone with NCGS, says Mukherjee. If a patient receives a normal test result
Still, its best to be up front with your doctor to receive the most accurate diagnosis. If youre concerned about these symptoms, feel free to tell your physician, Im concerned about a gluten problem, can we do any testing you deem necessary? advises Mukherjee.

You Have An Autoimmune Disease
An autoimmune disease is the term given when your immune system mistakenly attacks and damages your own tissue.
There are more than 80 types, characterised by which tissues or organs in the body are damaged.
Gluten intake is consistently linked with numerous types, but whether its the cause remains to be seen. Its influence in Celiac disease is the obvious example, but research indicates gluten likely affects Hashimotos hypothyroidism and Graves disease, to name a few.
Some researchers speculate the potentially negative effect of gluten is to do with the effect that gliadin may have on gut health and function .
In any case, it seems gluten intolerance is more likely in those with an autoimmune condition.

Getting A Proper Diagnosis Is Key
Getting a proper diagnosis is the first step toward feeling better and living a healthy life. Diagnosing celiac disease is pretty straight forward. A gastroenterologist will be able to make a diagnosis based on blood tests and a biopsy of the small intestine.
Diagnosing non-celiac gluten intolerance is a little trickier. Your physician will test you for celiac disease, wheat allergy and other things that might be associated with your particular symptoms. If you test negatively for those things, youll start a gluten-free diet. If going gluten-free for a while improves your symptoms, youll probably be diagnosed with non-celiac gluten intolerance.
If you think you might have a gluten intolerance, its important to keep gluten in your diet until you visit your physician. This is the only way the to test properly.

Tests For Food Intolerance
You may be referred to a food and nutrition specialist if a GP thinks you have a food intolerance.
Tests you may have include:
- a special diet where you avoid eating the food you might be intolerant to, to see if your symptoms get better after a few weeks you start eating the food again to see if your symptoms return
- a breath test if you might be lactose intolerant
You may also be asked to keep a food and symptoms diary to help work out what may be triggering your symptoms.
How To Get Tested For Gluten Intolerance
Before getting tested for gluten intolerance, its important to first rule out celiac disease for a number of reasons I detail in my article, STOP! Dont Go Gluten Free Until You Read This Article. You can get tested for celiac disease with this reliable and convenient at-home celiac disease test.
Inside the imaware kit youll find two lancets, 1 collection tube, plus an alcohol swab, baggie and bandage.
If youve ruled out celiac disease but believe you still have an issue with gluten or wheat, then its time to look to other diagnostic measures.
Unfortunately, diagnosing someone with a gluten intolerance is challenging because there isnt a firm consensus on how to do it and many doctors are in the dark about current testing protocols.
However, there is one test, the Wheat Zoomer test, that Dr. OBryan recommends that may be the magic bullet test the gluten sensitivity community has been hoping for.
Wheat Zoomer is a simple blood test that can determine if your body is making antibodies to wheat peptides including gluten and non-gluten components to determine if you have a gluten or wheat sensitivity. It also looks for antibodies that indicate the presence of intestinal permeability, wheat allergy, celiac disease, wheat germ agglutinin-related vitamin D deficiencies, gluten ataxia and other neurological symptoms, and dermatitis/eczema .

Whats The Difference Between Gluten Intolerance And Wheat Allergy
Because wheat is one of the major sources of gluten, it can be easy to confuse symptoms of gluten intolerance with those of a wheat allergy. However, there are very distinct differences.
All allergic reactions, including wheat, involve the immune system. It responds to what it thinks is a foreign substance that must be removed from the body. Your immune system releases antibodies known as immunoglobulin E , which trigger a variety of symptoms, including the possibility of a life-threatening condition known as anaphylaxis.
Having a gluten intolerance is less severe than a wheat allergy and does not involve the immune system. In addition, a trained allergist can diagnose a wheat allergy with a skin-prick or blood test, whereas a healthcare provider can only diagnose gluten intolerance based on your reported symptoms and ruling out other conditions.
However, because the two conditions can share many common symptoms, it is important to first rule out a wheat allergy before assuming gluten intolerance.
What A Doctor Can Do
If youre experiencing unusual symptoms and believe you might have CD, GS, a wheat allergy or another digestive condition, reach out to your healthcare provider . Your doctor can help pinpoint what ails you, refer you to the appropriate specialists and begin treatment to alleviate your symptoms. Avoid self-diagnosing your condition or eliminating gluten from your diet before your appointment, which could influence your test results, leading to a misdiagnosis and slower recovery.
And if your tests results reveal that you do not have a digestive issue related to wheat or gluten intake but youre still cutting them out of your diet to slim down or for some other perceived health benefit, you may want to reconsider. While some people may find it impels them to choose healthier foods in general, theres no real evidence that eliminating gluten will help you drop pounds or improve your overall wellbeing. Whats more, if youre not careful, eliminating gluten could deprive you of valuable nutrients especially fiber, but also iron and calcium. Many gluten-free foods are also loaded with added sugar, too much of which is unhealthy in itself.
In the end, the gluten decision is best left to you and your doctor and with a little knowledge, you can make the right choice for your health.

Wheat Allergy In Childhood
Allergic reactions often appear a few minutes to hours after a food containing wheat is consumed for the first time. However, delayed symptoms can also occur for example, eczema can worsen one to two days after eating wheat. The overall prognosis for wheat allergy is positive. Like cows milk and egg allergies, it usually subsides by adolescence. The allergist can perform a test 12 to 18 months following diagnosis to check whether the allergy is still present so that children may resume wheat consumption as soon as possible.
Symptoms And Causes Of Celiac Disease
People who have celiac disease commonly experience weight loss, as well as digestive symptoms, including diarrhea, abdominal pain, and bloating.
Some people notice mental and emotional symptoms, such as an inability to concentrate, commonly described as brain fog, or depression.
Not everyone with celiac disease experiences the same symptoms. Some people have no digestive complaints whatsoever, yet routine blood tests reveal low levels of vital nutrients, such as iron, vitamin B12, or vitamin D. NYU Langone doctors take all of these signs and symptoms into account when making a diagnosis.
The exact cause of celiac disease remains largely unknown. However, more than 99 percent of people with celiac disease test positive for two genetic variations known as HLADQ2 and HLADQ8. Not everyone who carries these variations develops celiac disease in fact, most people dont.
Some theories suggest environmental factors trigger celiac disease in people with these genetic variations, but more research is needed. Researchers have found that a family history of the disease increases a persons risk.

Gluten Intolerance Vs Celiac Disease
Its important to know that gluten intolerance and celiac disease are not the same. Someone who is gluten intolerant has digestive or other problems when eating food containing gluten. Gluten is typically found in wheat, barley, and rye. It can also be found in a laundry list of foods such as pasta, cakes, bread, and crackers.
A child who has celiac disease is suffering from an autoimmune disorder that can affect and damage their small intestine. Its often an inherited disease. In either condition, its important to stay away from foods that contain gluten in order to remain healthy.

Individuals with celiac disease experience inflammation in the small intestine after eating gluten.
This damages the gut lining and leads to poor nutrient absorption, resulting in significant digestive discomfort and frequent diarrhea or constipation (
That suggests that gluten exposure on its own may induce feelings of depression, irrespective to digestive symptoms.
Diagnosing Celiac Disease & Gluten Sensitivity
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.

How Is Gluten Intolerance Diagnosed
Your healthcare provider carefully reviews your symptoms and medical history. If they suspect you have a gluten intolerance, these are the next steps to confirm the diagnosis:
- Step 1: You eat a diet containing gluten for about six weeks. During this time, your healthcare provider performs blood tests and skin tests to rule out a wheat allergy or celiac disease. There isnt a gluten intolerance test.
- Step 2: If you dont have a wheat allergy or celiac disease, your healthcare provider will ask you to exclude gluten from your diet for at least six weeks. Keep a thorough record of your symptoms during this time, noting which symptoms improve.
- Step 3: If your symptoms do improve while youre on a gluten-free diet, you gradually reintroduce gluten back into your diet. If symptoms return, you likely have a gluten intolerance.

How To Go Gluten Free
Currently, researchers are determining if those with gluten sensitivity should go completely gluten free or maintain a low-gluten diet. Additionally, theyre evaluating which biomarkers help identify gluten intolerance for diagnostic reasons, with the hope of creating tailored treatment options.
Regardless of where the research currently stands, the first step to going gluten free entails ruling out celiac disease, Crohns, and other gut disorders. Afterward, follow an elimination diet. Its wise to consult a registered dietitian, who can help ensure your diets overall quality to reduce the risk of nutritional deficiencies, undesired weight loss, and poor energy intake. He/she can also help with the reintroduction phase, identify symptoms with food correlation, plus help navigate grocery shopping, recipe modifications, label reading, and social dining.

Managing Food Allergies In Children
Because fatal and near-fatal wheat allergy reactions, like other food allergy symptoms, can develop when a child is not with his or her family, parents need to make sure that their childs school, day care or other program has a written emergency action plan with instructions on preventing, recognizing and managing these episodes in class and during activities such as sporting events and field trips. A nonprofit group, Food Allergy Research & Education, has a list of resources for schools, parents and students in managing food allergies.
If your child has been prescribed an auto-injector, be sure that you and those responsible for supervising your child understand how to use it.
How Do You Test For Gluten Intolerance
Your doctor might recommend trying a gluten-free diet to see if you do have a gluten intolerance. Keep in mind that other conditions, such as celiac disease and wheat allergies, can cause similar symptoms. If eliminating gluten from your diet eases your symptoms, this usually indicates gluten intolerance. Your doctor can test for wheat allergies or celiac disease if needed.

Test To Tell If You’re Allergic To Gluten
Am I allergic to gluten? You ask. Well, there’re several tests for this. A gluten allergy is oftentimes difficult to diagnose. Many other conditions can create similar symptoms to gluten allergies, including celiac disease and gluten intolerance. Additionally, symptoms can vary in severity depending on the individual. The only way know for sure is to have yourself tested.
1. Elimination Diet
The first test used to ascertain whether someone has gluten allergies is with an elimination diet. With an elimination diet, people who suspect a gluten allergy removes foods that contain gluten, such as pasta, or wheat, from their diet for a length of time to determine if the symptoms are resolved. Unfortunately, an elimination diet will not completely rule out a gluten sensitivity, or celiac disease.
2. Blood/Skin Tests
A food allergy test such as a skin prick test, or pricking the skin with a needle or pin containing a small amount of the allergen can and do show gluten allergies. However, celiac/gluten intolerance is not an allergy, and the skin tests for allergies will not show it. There are blood tests for celiac/gluten intolerance, but there can still be some false negatives. Therefore, its usually followed up with stool antibody testing to see if you are throwing gluten antibodies into your stool.
3. IgE or Cell-Mediated Test
How To Know If You Have Non Celiac Gluten Sensitivity
Your doctor can test you for celiac disease. If you dont have it, that doesnt automatically rule out non celiac sensitivity.
There is two ways to test for that: an elimination diet or stool testing.
The challenge with testing through elimination diet is that some people can have a delayed reaction to gluten. It could take up to 3 or 4 days for symptoms to develop.
The most definitive way to test for gluten sensitivity is through the stool testing. The GI Map tests gliadin, a common immune marker for gluten.
If gliadin has a value of over 100 on the GI Map it suggests mild gluten sensitivity. Anything over 150 suggests a severe reaction. Youll have consume a small amount of gluten within 3 months of the test to get an accurate assessment. One bite of bread is sufficient.
Stool testing is one of the most effective ways to detect gluten sensitivity. The anti-gliadin antibody can be found in fecal samples even when blood concentrations are undetectable.
High levels of fecal anti-gliadin antibodies will determine whether a gluten-free diet is mandatory for healing the gut. If so, there needs to be 100 percent compliance to a gluten-free diet. One exposure can restart the cycle of gut inflammation for months.
Surprisingly, some of my clients, who follow a gluten-free diet, have high gliadin antibodies. This indicates inadvertent exposure to gluten, where out or at home.
