Approximately 1 in 5 children with celiac disease do not heal when following a gluten-free diet

Celiac disease is an autoimmune disease triggered by the consumption of gluten-containing foods. The medical approach for celiac disease is a lifelong gluten-free diet. However recent evidence demonstrates that a gluten-free diet may not be enough to prevent many complications associated with this disease. 

According to a new study published last week in the Journal of Pediatric Gastroenterology and Nutrition approximately 20% of children with celiac disease have intestinal abnormalities after one year following a strict gluten-free diet.

In this study researchers reviewed medical records of 103 children and adolescents with celiac disease. The participants followed a gluten-free diet for an average of 2.4 years. They also had an endoscopy and biopsy at least two times at diagnosis and after one year on the diet.

The study focused on the rate of persistent celiac enteropathy (damage to the intestinal cells caused by gluten) which was present in 19% of the children. These results suggest that 1 out of 5 children with celiac disease may have persistent enteropathy despite following their recommended gluten-free diet. This issue can lead to long-term effects and complications.

Few studies have looked at the effect of non-gluten proteins and celiac disease. An all-too-common contributor to non-responsive celiac disease is cross-reactivity with other foods. Assessing gluten-associated cross-reactive foods is essential for patients with gluten sensitivity and celiac disease since these patients are sensitized to a broad range of dietary proteins due to enzyme dysfunction villi damage and other disorders.

As a result many functional abnormalities can persist such as increased gut permeability pancreatic insufficiency small intestinal bacterial overgrowth (SIBO) also known as small bowel bacterial overgrowth syndrome (SBBOS) nutritional deficiencies hypochlorhydria and allergies.

Often patients with celiac disease have to do more than just follow a gluten-free diet to maintain optimal health. Although a majority of celiac patients feel better after implementing this type of diet they continue to have poor nutrient status. Celiac disease attacks and damages the villi of the small intestine resulting in the body not being able to absorb all the nutrients it needs. The most common deficiencies are vitamin D calcium folate vitamin B12 and iron. Therefore it is important to assess the nutrient status. This can be antioxidant status vitamins essential fatty acids vitamin D etc. In addition it is essential to use stool testing that can assess the overall function of the gastrointestinal tract to rule out autoimmune triggers digestion and absorption issues as well as inflammatory and immune problems.
