Research Into Non Coeliac Gluten Sensitivity
Non coeliac gluten sensitivity is a condition that is being recognised as a problem in many countries across the world. This is a new area and we need more research to understand the condition and who is at risk. There are no specific diagnostic tests for non coeliac gluten sensitivity.
Some researchers define non coeliac gluten sensitivity as an improvement in symptoms when following a gluten free diet. However, it is difficult to rule out the possibility of a placebo effect.
There is also some debate around whether gluten is the cause of the sensitivity or if other components are to blame. These components are also removed from the diet when gluten containing ingredients are removed, for example Fermentable Oligo- Di- Mono-saccharides and Polyols and other non gluten proteins found in wheat.

The recommends that people talk with a doctor if they do not feel well or are concerned about their risk of developing a health condition.
The FDA also states that people should regularly visit a doctor, regardless of whether they feel ill.
When Should I Call My Doctor
Some symptoms of gluten exposure can be severe. Seek medical attention if you experience diarrhea or vomiting. Dehydration can lead to dangerous electrolyte imbalances.
A note from Cleveland Clinic
Gluten intolerance may make you feel sick after eating gluten. You might get bloated, nauseous or gassy. Gluten intolerance causes a lot of the same symptoms as celiac disease, but its not the same condition. Celiac disease is an autoimmune disorder that leads to damage to the digestive tract. People with gluten intolerance usually find relief from their symptoms by following a gluten-free diet. Gluten-free diets do have some health risks. Its important to work with your healthcare provider and a dietitian to build the right treatment plan for your needs.

What is Gluten Intolerance?
Gluten sensitivity or intolerance is a condition that causes a person to react after ingesting gluten, a protein found in wheat, barley and rye. Gluten causes an autoimmune response in the body which damages the small intestine. Its estimated that 99% of the people who have either gluten intolerance or celiac disease are never diagnosed. It is also estimated that 15% of the US population is gluten intolerant.

Many people remove gluten from their diet after a long history of health complaints and unsuccessful consultations with numerous physicians, who simply consider them to be suffering from irritable bowel syndrome, and some may eliminate gluten before seeking medical attention. This fact can diminish the CD serological markers titers and may attenuate the inflammatory changes found in the duodenal biopsies. In these cases, patients should be tested for the presence of HLA-DQ2/DQ8 genetic markers because a negative HLA-DQ2 and HLA-DQ8 result has a high negative predictive value for celiac disease. If these markers are positive, it is advisable to undertake a gluten challenge under medical supervision, followed by serology and duodenal biopsies. However, gluten challenge protocols have significant limitations, because a symptomatic relapse generally precedes the onset of a serological and histological relapse, and therefore becomes unacceptable for many patients. Gluten challenge is also discouraged before the age of five and during pubertal growth.
For people on a gluten-free diet who are unable to perform an oral gluten challenge, an alternative to identify possible celiac disease is an in vitrogliadin challenge of small bowel biopsies, but this test is only available at selected specialized tertiary-care centers.

Clinical Presentation And Diagnosis Of Ncgs
The clinical presentation of NCGS is variable with multiple intestinal and extraintestinal symptoms occurring within hours, but in some patients only after several days upon the ingestion of gluten. The Salerno Experts criteria list bloating and abdominal pain as the most frequent GI symptoms, followed by diarrhea, epigastric pain, nausea, and alternating bowel habits or constipation. Some patients also report oral aphthous ulcerations or reflux symptoms evoking gastroesophageal disease. Frequent extraintestinal symptoms are a general lack of wellbeing, headache, tiredness, anxiety, but also muscle and joint pain, skin rash/dermatitis, anemia, numbness or foggy mind are reported. Even less specific symptoms such as sleeping disturbances, mood swings, or hallucinations were reported after gluten ingestion. The great majority of intestinal symptoms overlap with classical celiac disease and even more importantly with either forms of IBS, diarrheal IBS, or IBS with constipation . A small pediatric study on 15 children with gluten sensitivity reported that intestinal symptoms are clearly predominant with abdominal pain as the lead symptom , followed by diarrhea , while extraintestinal symptoms were markedly less frequent .

Rationale Behind Adoption Of The Diet
is a chronic, immune-mediated, and mainly intestinal process, caused by the ingestion of wheat, barley, rye and derivatives, that appears in people of all ages. Coeliac disease is not only a gastrointestinal disease, because it may affect several organs and cause an extensive variety of non-gastrointestinal symptoms, and most importantly, it may often be completely asymptomatic. Added difficulties for diagnosis are the fact that serological markers are not always present and many people with coeliac may have minor mucosal lesions, without atrophy of the . A 2017 study found that gluten is not related to a risk of coronary heart disease in people without celiac disease.
Coeliac disease affects approximately 1%â2% of the general population all over the world and is on the increase, but most cases remain unrecognized, undiagnosed and untreated, exposing patients to the risk of long-term complications. People may suffer severe disease symptoms and be subjected to extensive investigations for many years before a proper diagnosis is achieved. Untreated coeliac disease may cause , reduced , , , obstetric complications , an increased risk of intestinal and greater mortality. Coeliac disease is associated with some autoimmune diseases, such as , ,, , , , , , and more.
Following a lifelong gluten-free diet is the only medically-accepted treatment for people with coeliac disease.

Us Food Intolerance Core Test
U.S. Food Intolerance offers several home tests for food sensitivities based on IgG measurements. Their basic test, the Core Test, can check for sensitivity to gluten and around 300 foods.
However, it is worth keeping in mind that no evidence indicates that food sensitivity tests based on IgG levels correlate with symptoms.
To take the test, a person needs to give a hair sample.
U.S. Food Intolerance says that results come back within 5 days of the lab receiving the sample. The report includes a complementary metals and nutritional deficiency test.
Conflicting Data From Clinical Trials
To date, several CTs and RCTs addressing the NCWS issue with different designs, controversial results, and numerous limitations have been published. In Table , most of the RCTs on NCWS are listed chronologically with some of the restrictions . Conflicting results of clinical trials are a problem but probably not the only one. In examining some of these trials, we highlight these conflicts, but the overemphasis may also be a problem. A randomized, double-blind study reported that dietary gluten, provided in the context of low FODMAPs , induced symptoms compared to placebo in patients who had no histological or serological evidence of celiac disease . The Finnish study performed at the Department of Internal Medicine of the Tampere University Hospital evaluated 93 consecutive adults from health centers spontaneously reporting abdominal symptoms after consumption of cereals. Nine percent of patients had celiac disease, of which 17 had an increased density of gamma delta +intraepithelial lymphocytes without atrophy.
Table 1 Randomized clinical trials
On the other hand, only 8% of patients showed evidence of celiac disease, i.e., both an increase in +IELs and the presence of celiac disease-type HLA. Approximately 20% had one or more positive allergy tests for cereals. In the patients who adopted a GFD, all abdominal symptoms were alleviated. However, methodological deficiencies have been delineated .

Outlook For Children With Ncgs
The medical community is still learning about non-celiac gluten sensitivity, but recent research provides reason for hope. Unlike celiac disease, NCGS doesnt cause long-term damage to the patients intestines, and some research indicates NCGS may not be a lifelong condition.
As scientists learn more about NCGS in the future, your CHOP doctor can keep you updated on anything that is discovered about causes, risk factors for other diseases as well as any developments regarding new treatments.

If The Symptoms Are So Similar How Is Gluten Sensitivity Different From Celiac Disease
Gluten sensitivity has been clinically recognized as less severe than celiac disease. It is not accompanied by the enteropathy, elevations in tissue-transglutaminase, endomysium or deamidated gliadin antibodies, and increased mucosal permeability that are characteristic of celiac disease . In other words, people with gluten sensitivity would not test positive for celiac disease based on blood testing, nor do they have the same type of intestinal damage found in individuals with celiac disease. Some individuals may experience minimal intestinal damage, and this goes away with a gluten-free diet.
Research has also shown that gluten sensitivity does not result in the increased intestinal permeability that is characteristic of celiac disease. Increased intestinal permeability permits toxins, bacteria and undigested food proteins to seep through the GI barrier and into the bloodstream, and research suggests that it is an early biological change that comes before the onset of several autoimmune diseases.

When To See A Doctor
Home tests may indicate whether a person has celiac disease, but anyone with symptoms of gluten intolerance may have to visit their doctor for a diagnosis.
No effective gluten sensitivity blood or stool tests exist. Doctors diagnose it by ruling out other conditions and encouraging the person to try an elimination diet.
How Can I Get Tested For Non
Currently, there are no recommended methods to test for non-celiac gluten sensitivity . Some doctors offer saliva, blood or stool testing. However, these tests have not been validated and are therefore not accepted.
In the Beyond Celiac webcast, Dr. Guandalini adds to the fact that there are no reliable tests at this time, stating:
No antibodies in the blood are specific enough, or sensitive enough, for this condition. No antibodies in the stools can be utilized to diagnose or screen for this condition.
Dr. Fasano also touched on this topic and stated that his team is currently conducting research to identify biomarkers that may help to test for and diagnose non-celiac gluten sensitivity also known as gluten intolerance.

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.
Living With Gluten Intolerance
Fortunately, with gluten intolerance awareness at an all-time high, there are no shortages of gluten-free alternatives to your favorite foods, and today, transitioning into a gluten-free diet is easier than ever. Transitioning to a gluten-free diet will certainly help alleviate symptoms of gluten intolerance. However, simply removing gluten from your diet without following up with a doctor is not recommended.
For one thing, your doctor will want to determine if your reactions are being caused by Celiac disease, intolerance, sensitivity or an allergy. In order to test for all of these, gluten needs to be in your system, so do not eliminate gluten until after you have been tested.
If a Celiac test comes back negative, the next thing your doctor will want to do is have you follow an elimination diet and monitor the results. Its possible that gluten is not the real culprit and, by the process of elimination, your doctor or dietician may be able to find the real source of your symptoms. Its important to remember that gluten intolerance cant be confirmed or ruled out with one simple test. That being said, there are a number of factors that might indicate you are at a higher risk of gluten intolerance including genetic factors. Rather than trying to figure out if you have Celiac disease or gluten intolerance by yourself, you must involve medical health professionals to get a proper diagnosis.
