Non-Coeliac Gluten Sensitivity: A full exploration and explanation of this new medical term

Pink and blue image with plain background and a floating question mark to represent the question within the title of this post, "what is non-coeliac gluten sensitivity?".

If you’re looking to understand Non-Coeliac Gluten Sensitivity, you’re in the right place.


This article will provide a comprehensive understanding of non-coeliac gluten sensitivity and will be especially helpful if you’re new to gluten-free living or seeking to deepen your knowledge of this new and evolving medical term.


Non-Coeliac Gluten Sensitivity (NCGS) is the term now being used to describe symptoms associated with eating gluten, but where coeliac disease and wheat allergy have been ruled out.


Read on to find out more about NCGS and it’s similarities and differences to Coeliac Disease and other gastrointestinal conditions.

Introduction:

Let’s kick off todays post by clearly defining non-coeliac gluten sensitivity. There’s significant misunderstanding around this relatively new term, and it’s crucial to grasp its inclusivity.

Non-Coeliac Gluten Sensitivity (NCGS)

NCGS is a condition characterized by the occurrence of intestinal and extra-intestinal symptoms after gluten consumption. Importantly, it lacks the autoimmune response seen in coeliac disease and does not involve a wheat allergy.


Symptoms in NCGS closely resemble those of coeliac disease, as discussed in the podcast and in my other recent article called “what is coeliac disease?”. While coeliac disease is a lifelong autoimmune condition leading to intestinal damage, NCGS is not autoimmune. However, both conditions share the same treatment—adopting a gluten-free diet.

  • Symptoms Resemblance

    • Similarities to coeliac disease symptoms
    • Distinctive feature: Not autoimmune
    • Not inclusive of wheat allergy
    • No biomarkers for testing

The Recognition Challenge

Currently, NCGS faces a lack of deserved recognition, with conflicting studies on its exact cause. Diagnosis is challenging due to the absence of specific tests or biomarkers.


Typically, it involves a process of elimination, ruling out coeliac disease, wheat allergy, and sometimes irritable bowel syndrome (IBS).


Diagnosing NCGS is further complicated by varying opinions within the medical community about the root cause of symptoms. Some argue that the term is too specific, leading to alternatives like non-coeliac wheat sensitivity.


This shift is influenced by emerging studies suggesting FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) might be responsible for symptoms attributed to gluten.


If you want to know which dairy foods contain gluten, check out this helpful article of mine. It might help ease some of your symptoms if you’ve been choosing dairy products so far which are not gluten free.

Diagnostic Complications

  • Lack of specific tests and biomarkers
  • Process of elimination
  • Contrasting medical opinions

FODMAPs and NCGS

FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) might be responsible for symptoms attributed to gluten.


FODMAPs and NCGS: FODMAPs are short-chain carbohydrates not fully digested by the body, found in gluten-containing foods.


Their fermentation by gut bacteria produces gas and attracts water, potentially causing discomfort and bloating.

Decoding FODMAPs

  • Short-chain carbohydrates
  • Fermentation process
  • Gas and water production

NCGS vs. IBS

NCGS bears similarity to Irritable Bowel Syndrome (IBS), but they are distinct conditions. Both lack specific diagnostic tests, relying on symptom presentation and a process of elimination.

Symptoms Overlap

  • Fatigue, headaches, stomach pains, bloating
  • Joint and muscle pains, foggy mind
  • Dermatitis, anxiety, depression, anaemia

A shift in medical terminology

The terms “gluten sensitivity” or “gluten intolerance” are now encompassed by NCGS, streamlining the diagnosis of gluten-related conditions in the absence of coeliac disease and wheat allergy.

What does the future look like for NCGS diagnosis?

While NCGS is presumed to be prevalent, challenges in effective diagnosis may lead to self-diagnosis, possibly overestimating its prevalence. Future advancements in medical diagnostics are anticipated to refine NCGS identification and determine its precise cause, be it gluten or FODMAPs.


In the upcoming years, the medical industry’s efforts to accurately diagnose and understand NCGS will likely shed light on whether it should be recognized as a distinct condition, eliminating confusion and ambiguity.

Path Ahead

  • Accurate diagnosis
  • Distinct condition recognition
  • NICE recommendations and pathway for diagnosing
  • Further research to establish root cause

Grey Areas and Misdiagnoses

The similarities between IBS, NCGS, and CD often lead to misdiagnoses. Let’s explore this gray area further, discussing the commonalities and distinctions between coeliac disease and non-coeliac gluten sensitivity.


Symptoms overlap significantly, encompassing fatigue, headaches, stomach pains, bloating, joint and muscle pains, foggy mind, dermatitis, anxiety, depression, and anaemia.


The crucial disparity lies in coeliac disease being a lifelong autoimmune condition causing intestinal damage, requiring a lifelong gluten-free diet.


In contrast, NCGS, despite similar symptoms, is not autoimmune, and currently, it’s understood that it doesn’t lead to intestinal damage. This differentiation is pivotal.

Symptom Similarities

  • Bloating, foggy mind, dermatitis
  • Joint and muscle pains, anxiety, depression
  • Crucial Disparity

How does diagnosing NCGS work compared to diagnosing Coeliac Disease?

When it comes to diagnosing coeliac disease or non-coeliac gluten sensitivity (NCGS), medical professionals typically conduct blood tests to identify specific biomarkers associated with coeliac disease. Simultaneously, they often check for the presence of wheat allergy.


In contrast, diagnosing NCGS is more challenging due to the absence of specific biomarkers for testing. Generally, NCGS diagnoses stem from negative test results for coeliac disease and wheat allergy.


The National Institute for Health and Care Excellence currently lacks specific guidelines on the diagnostic process for NCGS, adding an additional layer of complexity to the diagnosis.


Despite the absence of strict guidelines, some general recommendations can assist in determining the potential presence of NCGS.


This involves following a gluten-containing diet for at least six weeks, followed by a period of adhering to a gluten-free diet while monitoring symptoms and reactions to food.


The common assumption is that if an individual, suspected of having NCGS, does not experience improvements in symptoms and overall well-being after six weeks on a gluten-free diet, NCGS may be less likely as the cause.


In such cases, further investigation is warranted to explore the possibility of other gastrointestinal issues like small bowel bacterial overgrowth, irritable bowel syndrome (IBS), or similar conditions.

Diagnostic Approaches

  • Blood tests for coeliac disease
  • Wheat allergy checks

NCGS Diagnostic Challenges

Diagnosing NCGS is more challenging due to the absence of specific biomarkers for testing.

Diagnosis Complexities

  • Lack of specific guidelines
  • Process of elimination
  • Gluten-containing diet trial

Conclusion:
How to Navigate the Diagnostic Journey of NCGS

In dealing with symptoms that suggest Non-Coeliac Gluten Sensitivity (NCGS) or Coeliac Disease, obtaining sufficient support and assistance is crucial for an accurate diagnosis. Given the current lack of comprehensive knowledge and research on NCGS, the diagnostic journey may encounter various challenges. Nevertheless, symptoms indicative of either CD or NCGS should not be dismissed.
