Celiac Disease Often Appears Alongside Type 1 Diabetes and Other Autoimmune Conditions

A new study from Romania found that nearly one-third of children with celiac disease also have other autoimmune conditions, with Type 1 diabetes being among the most common. Understanding this connection matters for diagnosis and care.

Key takeaways

About 31% of children diagnosed with celiac disease in this study had at least one other coexisting autoimmune condition, most often Type 1 diabetes or autoimmune thyroiditis
Children with both celiac disease and other immune conditions were often diagnosed later and were more likely to have no obvious symptoms at the time of diagnosis
Girls were significantly more likely than boys to have celiac disease alongside other immune conditions
This Romanian data adds to growing evidence that autoimmune conditions cluster together in children and highlights the importance of screening for related conditions

Why This Matters for Type 1 Diabetes Families

Type 1 diabetes and celiac disease are both autoimmune conditions—meaning the body's immune system attacks its own cells. Research shows these conditions often occur together, but how common this overlap actually is varies by region. This new study from North-Eastern Romania helps fill gaps in understanding how often children with Type 1 diabetes might also develop celiac disease and other immune-related disorders.

What the Study Found

Researchers reviewed medical records for 58 children diagnosed with celiac disease between 2020 and 2024 at a pediatric center in Romania. They found that 18 of these children (31%) had at least one additional autoimmune condition. Type 1 diabetes and autoimmune thyroiditis (an autoimmune thyroid disease) were the most frequent companions to celiac disease.

The study also noticed important differences between the two groups. Girls outnumbered boys by more than 3 to 1 overall, and this female predominance was even stronger in children who had celiac disease plus other immune conditions. Children with multiple immune conditions tended to be older when celiac disease was found, and many showed no symptoms at diagnosis. In contrast, children with celiac disease alone were usually diagnosed because they had visible symptoms like digestive problems or other signs of illness.

What This Tells Us About Screening and Diagnosis

One important finding is that children with multiple autoimmune conditions often don't show obvious warning signs. This suggests that families and doctors managing Type 1 diabetes should be aware that celiac disease might be present even without gastrointestinal complaints. The study also shows that girls are at higher risk, which can help guide who to screen.

The research was conducted using 2020 ESPGHAN (European Society for Pediatric Gastroenterology, Hepatology and Nutrition) diagnostic guidelines, which now allow doctors to confirm celiac disease without a biopsy in selected cases. This can make diagnosis faster and less invasive for children who meet specific criteria.

Next Steps for Families

While this study is from one center in Romania, it adds to global evidence that autoimmune diseases tend to cluster in certain individuals. If your child has Type 1 diabetes, talking with your healthcare team about screening for celiac disease and other autoimmune conditions may be worthwhile—particularly if your child is a girl or if there are family members with autoimmune diseases. However, screening decisions should be made with your own medical providers who know your family's history and circumstances.
