The singer, who recently turned 70, became “violently ill” during a flight back to the UK following a show in Santiago, Chile earlier this month and was rushed to hospital.
He is understood to have spent around 12 days in hospital, including his two nights in intensive care.
The star is now recuperating at his home and has cancelled all his tour dates for the next two months, including his long-standing residency at Caesars Palace in Las Vegas.
He was released from the hospital on Saturday, and is now "comfortably resting at home per doctor's advice."
He is expected to make a full recovery, and is set to resume performing in Twickenham on June 3.
In a statement, he said: "I am so fortunate to have the most incredible and loyal fans and apologise for disappointing them.
"I am extremely grateful to the medical team for their excellence in looking after me so well."
