In addition, stomach surgery (gastrectomy), weight-loss surgery and conditions such as Crohn's disease, celiac disease and Cushing's disease can affect your body's ability to absorb calcium.

These conditions are reported to be more common in women with untreated celiac disease, though miscarriages have many causes and occur in up to one-fourth of all pregnancies.

Still, my own clinical experience suggests that infertility and smaller or preterm babies are more common in women with untreated celiac disease than those without.
