The author and model, 38, revealed the diagnosis after fans noticed his glucose monitor in a photo she shared during the Olympics.
In the image, Miles was holding a sign and wearing a short-sleeved yellow shirt, which made his continuous glucose monitor visible on his upper arm.
Addressing the curiosity on Instagram, Teigen wrote: “Many of you noticed something special in a photo I posted a few days ago — Luna, Miles, and I celebrating Simone and Team USA.”
“Miles had his arm up, and so many of you reached out with the most beautiful and incredible words I have ever received on this platform. You noticed his type 1 diabetes monitor and offered so much love and encouragement. I am deeply touched by the kindness of this community.”
Teigen also mentioned that “things could be so much worse” and expressed gratitude for the support of a specialist. She shared that Miles had been hospitalized a few weeks ago with a severe case of shigella, an intestinal infection caused by bacteria in food or water. Many of his friends from the same camp were also affected.
“The doctors noticed something unusual in his blood tests. I’ve learned that many young children are diagnosed with type 1 diabetes after being hospitalized for something else,” Teigen explained.
“After further testing, we discovered that Miles is in the ‘honeymoon period’ of his type 1 diabetes,” she continued. “Last night, we gave him his first insulin shot, and here we go! We’re entering a new world and learning as we go.”
Teigen concluded by thanking everyone for their kindness and support, noting that it helps Miles feel less alone. She and her husband, John Legend, 45, have been using the book Year One with Type One to assist Miles with his diagnosis.
