John Legend shares how his son's 'life-changing' diagnosis made him and Chrissy Teigen a 'stronger' couple

John Legend says that his son Miles' diabetes diagnosis has made him and wife Chrissy Teigen a 'stronger' couple.

Speaking to PEOPLE on Saturday, the singer, 45, recalled the moment they learned the six-year-old had type 1 diabetes.

Miles had fallen ill while at summer camp, which led to what the couple thought would be a simple trip to the emergency room.

'I remember he was at the emergency room because of it and they checked his blood sugar,' the singer explained. 'The thinking was, this may be a reaction to the infection or he may be diabetic.'

He continued: 'They did some more tests and decided it was the latter; that he was type 1 diabetic. Chrissy was upset a little bit when she first heard. She's been so good at learning what she needs to do.'

And Legend assured the outlet that he was 'very optimistic' and 'practical' about the situation.

'As soon as I learned that he had this I knew it was going to be life-changing for him and for us, but I'm also like, "We can do this,"' he explained. 

'We've got great advice and lots of people offering support to help us learn,' the Beauty and the Beast singer added.

'This speaks to us feeling like a team and knowing we can do this. It just makes us stronger,' The singer said of he and his wife.

The father-of-four also explained that Miles is in the 'early' stages of his diagnosis and that he and his model wife 'have to be more aware.'

He shared: '[Miles is] early in his diagnosis, and when you're early, your insulin is still doing some of the work that it needs to do. But as the disease progresses, it's going to get to a point where we really need to monitor everything, count carbs, give him insulin beforehand. We just have to be more aware.'

According to the Mayo Clinic, type 1 diabetes is a condition where 'the pancreas makes little or no insulin. 

'Insulin is a hormone the body uses to allow sugar (glucose) to enter cells to produce energy.'

The clinic also says that the disease can be attributed to genetics and certain viruses. It typically appears during adolescence but can be diagnosed during adulthood as well. 

Those managing it must regulate the amount of sugar in their blood by using insulin and dieting. Type 1 diabetes has no cure.  

Little Miles was recently spotted wearing an insulin monitor while out watching gymnastics with his family during the Paris Olympics. 

Sharing a photo of Miles and daughter Luna, eight, holding up signs at the Paris Olympics, Chrissy Teigen wrote: 'A lot of you noticed something a little special about a photo I posted a few days ago — Luna, Miles and I celebrating Simone and team USA.

'Miles had his arm up, and soooo many of you reached out to say the most beautiful and incredible words I have ever witnessed on this platform.

'You noticed his type-1 diabetes monitor and extended so much love and encouragement in every way possible. I was, and am, so blown away by the kindness of this community, already,' she said.

Chrissy added that 'things could be so much worse' and her family feels blessed to have the help of a specialist.
