The 59-year-old Good Morning Britain presenter began to sound increasingly hoarse during a news broadcast during the ITV program on Monday, September 14.
She apologized to viewers before being replaced mid-show.
Ms Garraway said: “I owe you an apology, I’m so sorry.
“I’m not in pain at all, I don’t feel bad, but last week I talked too much.
“So it’s a bit like the news was brought to you by Barry White this morning, so I hope it doesn’t interfere with your understanding of the important stories we have.”
During the story, GMB reporter Jonathan Swain, who was reporting from Glasgow, told Ms Garraway he would bring her a cough drop when he returned to London.
Back in the studio, hosts Susanna Reid and Ed Balls asked about the reason for her hoarse voice.
Ms Reed suggested it may have been due to singing “I Know Him So Well” alongside Amanda Holden, Paloma Faith, Charlotte Church and David Olusoga while honoring Alan Carr at the National Television Awards on September 8.
Mr Balls joked it could have been “over-the-top Saturday night karaoke”, which Ms Garraway denies.
She said: “I talked and sang last week!
“I lost my voice on Friday and Saturday nights.”
She then joked: “Now Aled Jones wants to do a Christmas album with me and I think maybe it’s a result of that terror, I don’t know.
“I know it sounds really painful—sorry—but it doesn’t really hurt.”
Ms Reid turned to weather presenter Laura Tobin for advice, who recommended “hot water, honey and lemon”.
Ms Garraway replied: “I have it.
“Anything else?”
Ms. Tobin advised: “And don’t talk.”
Ms Garraway laughed and said: “Out of character, Laura!”
Later in the program Ms Reid told viewers Ms Garraway had gone home.
She said: “As you may have noticed this morning, Kate Garraway had a very husky voice; she sang it at the National Television Awards last week and her voice has yet to fully recover.
“So we put her on voice rest and Faye Barker valiantly came to the rescue and is here with the rest of the morning’s news.”
Ms Barker joked: “Morning, it’s amazing who you can find in the ITN cupboard when you need it!”
