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 U.S. 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.
On Friday, she canceled her remaining British dates. Ticket holders will receive refunds.
