Chrissy Teigen & John Legend’s son Miles diagnosed with Type 1 Diabete

The model, 38, shared that Miles, 6, was recently diagnosed with Type 1 diabetes after being hospitalized for a separate illness.

“A couple weeks ago, our Miles was sick in the hospital with a terrible case of shigella, an intestinal infection caused by bacteria in food or water,” Chrissy wrote in a July 31 Instagram post. “A lot of his friends were also sick with it, as they went to the same camp and well, it happens!”

While being treated for the illness, Chrissy—who also shares daughters Luna, 8, and Esti, 18 months, as well as son Wren, 13 months, with John—said Miles’ medical team discovered there was more than just an infection.

“The doctors knew something else was off about his blood tests,” she continued. “After more testing, we learned he is in the ‘honeymoon period’ of a lifetime of [Type 1 diabetes].”

As for the journey ahead, Chrissy said they have already started making adjustments to his routine.

“Last night we gave him his first shot of insulin and here we go!” she said. “A different, new world for us and we are certainly learning so much on the fly.”
