Columbia Records said in a statement that Adele, 23, was canceling the appearances with "deep regret."
"She is to undergo surgery to alleviate the current issues with her throat and a full recovery is expected. As a result, doctors have ordered her to rest her voice and completely recuperate" before resuming work commitments, the statement said.
Earlier this month the Grammy-winning singer pulled out of 10 US dates on the back of her hit album "21" that has produced hits such as "Rolling in the Deep" and "Someone Like You."
"21" is the best-selling album of the year in the United States.
Today, she cancelled her remaining British dates. Ticket holders will receive refunds.
Adele was forced to postpone several US dates earlier this year due to vocal chord issues and was finishing up a tour in Britain when problems reappeared in early October.
She topped the American Music Awards nominations on Oct. 11, edging out the likes of Katy Perry and Lady Gaga with four nods.
