The Study
GUT DYSBIOSIS AND ADHERENCE TO A GLUTEN FREE DIET MAINTAINING A BALANCE BETWEEN TREATMENT AND ADVERSE EFFECTS AMONG INDIVIDUALS WITH CELIAC DISEASE AND NON-CELIAC GLUTEN HYPERSENSITIVITY
This article is like a summary of other people's stories about what happens when people stop eating gluten. It doesn't do any experiments itself, so we can't say for sure that gluten-free diets cause changes in gut bacteria — it just says some studies noticed a possible link.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
When people with celiac disease or gluten sensitivity stop eating gluten, their gut bacteria change in ways that might make them sicker—even though they feel better. Their good bacteria go down, bad bacteria go up, and they miss out on important nutrients.

Quality score
Systematic reviews and meta-analyses of cohort studies. They sit above a single cohort study but below a single randomized trial, because the underlying evidence is still observational.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes—these changes may cause long-term digestive problems, nutrient deficiencies, and inflammation, even if gluten is avoided.
- 2Gluten-free diets lower good bacteria like Lactobacillus and Bifidobacterium, raise bad bacteria like E.
- 3coli, and reduce fiber, B vitamins, and iron intake.
- 4Oral bacteria that break down gluten also increase.

In people with autoimmune thyroid conditions, eating certain foods causes measurable negative changes in bodily functions.
In people with celiac disease or non-celiac gluten hypersensitivity, following a gluten-free diet is associated with specific changes in gut bacteria, including lower levels of Lactobacillus and Bifidobacterium and higher levels of Enterobacteriaceae and Escherichia coli, which are linked to gut microbial imbalance and increased bacterial movement across the intestinal barrier.
People who follow a gluten-free diet consume less dietary fiber, B vitamins, and iron, which leads to lower nutrient levels and changes in gut bacteria composition.
People with celiac disease have different bacteria in their mouths, including higher levels of Streptococcus, Neisseria, Actinomyces, and Rothia, which break down gliadin peptides into forms that trigger intestinal inflammation.
Probiotics and prebiotics may restore gut microbiota balance in people with celiac disease or non-celiac gluten hypersensitivity after starting a gluten-free diet, but there is not enough evidence to recommend them as standard treatment.
There are no reliable biological tests to diagnose non-celiac gluten hypersensitivity; diagnosis depends on ruling out celiac disease and wheat allergy, then exposing individuals to gluten, which results in inaccurate identification of affected populations.
