Good Morning Britain anchor Kate Garraway, 52, has taken to Twitter to praise the NHS as she recalled her own health battle, which occurred minutes before she was due to go air last year.Speaking from the Smooth Radio studios last month, she addressed the moment she was rushed to hospital after feeling dizzy and sick.In view of the radio show’s 38,000 Twitter followers, she said in a video: “About a year ago, maybe a bit longer, I saw first-hand at how brilliant the NHS are in a crisis.“I got up at 2am in the morning, went into Good Morning Britain at 3 and I had a raging temperature.“I felt dizzy, I felt sick, it was clear to producers then that I couldn’t broadcast.
