Celiac Disease Linked to Infections Early in Life
The team from Umeå University and Uppsala University found that having
three or more infections (reported by parents) increased risk of celiac
disease by 50%. Gastroenteritis on its own increased the risk by 80%.
The highest risk was seen for children who had several infections before
they were six months old and who also ate large amounts (compared to
small/medium amounts) of gluten, soon after gluten was introduced, and
if breastfeeding had stopped before the introduction of gluten to the
babies’ diet.
They apparently did not track antibiotic use. I bet that would be significant.
