Opening up to the publication, she revealed: "He's not doing great, to be honest. But the battle goes on."
Kate's husband Derek first fell seriously ill back in 2020 when he contracted COVID-19. He is now the longest surviving coronavirus patient in the UK and requires round-the-clock care at home.
The 56-year-old spent 13 months in hospital before finally being allowed to move back to his family home, where Kate and specialist nurses have been taking care of him ever since.
This isn't the first time Kate has spoken about her loved one's health battle. Last month the broadcaster shared a glimpse inside Derek's "emergency setbacks" during a candid interview with Good Housekeeping.
The author and documentary maker said: "I'd love to be able to tell you that, since Derek has been home, everything has been easy, that the miracle of him being at home has turned the day-to-day challenges into a breeze.
"But because we keep having emergency setbacks and he's had to be rushed back into hospital so many times, the fear of him dying has never left us. The unpredictability of his day-to-day condition means we're living on a rollercoaster."
Derek's ongoing health battle has also had a lasting effect on the couple's two teenage children Darcey and William.
During a recent appearance on This Morning, Kate revealed how their kids are now dealing with their "own traumas".
She said: "He is most alive when they're around. They are unbelievable. I haven't really talked a lot about them in some ways, but they've had their own traumas and it's not my story to tell."
Kate went on to say: "So maybe one day they'll tell it, I want to try and protect them in that way, but they've been amazing with him in their different ways. They're so intuitive and it is love, I guess, isn't it."
What treatment is Derek Draper receiving?
In February 2022, Kate revealed that she had visited a specialist clinic in Mexico after an eminent doctor saw her Finding Derek documentary and got in contact with the TV star.
Kate said she's reluctant to share too much about what the treatment is, telling her GMB co-stars: "I want to be slightly careful about saying too much, because I'm aware everybody will go, 'What is the trial?'"
"It's all come about because of the first documentary. This is a doctor who works in the US and he's been working for 13 years on clinical trials of this treatment and he is just at the point of waiting for approval on it and of course, 11 years ago there was no such thing as Covid so he's been looking at it for other things."
