Dylan Dreyer is sharing an important health update related to her son.

The Today meteorologist said that her 6-year-old son Calvin—who she shares with husband Brian Fichera—had been diagnosed with celiac disease.

“The bloodwork came back with the results of him having celiac disease,” she told Today in an interview published May 24. “I knew nothing about celiac disease. I knew a friend of a friend had it, and she couldn’t eat bread. That’s basically the knowledge I had.”

The diagnosis came after Calvin had suffered stomach pain, earaches, rashes and hair loss for about a year. His stomach pain reached a point where he was “hunched over in pain,” which led his family to rush him to the hospital in fear of an appendix burst. It was that hospital visit that prompted the family and doctors to conduct further research into his condition.
