Sir Elton is recovering following surgery to remove his appendix, his publicist has confirmed.
The 66-year-old underwent the operation at Monaco's Princess Grace Hospital on Thursday and has been resting at his home in Nice, France.
Elton was forced to cancel a series of summer shows last month after being diagnosed with appendicitis, including a headline gig in London's Hyde Park.
He admitted to performing 10 shows "in agony" before he called doctors.
"I was a ticking time bomb. I guess I could have died at any time. I feel so lucky and grateful to be alive," he remarked.
The songwriter is expected to be well enough to take the stage in September.
