Singapore's Prime Minister Lee Hsien Loong on Monday sent his heartfelt thanks to Singaporeans for their concern and good wishes.

Lee wrote on his Facebook that he felt sorry for he did not have the chance to meet Singaporeans all after National Day Rally on Sunday night, as he went straight to Singapore General Hospital for a thorough check-up.

Lee took ill during the English portion of his speech at the Rally on Sunday. The Prime Minister's Office said in a statement on Monday that doctors have confirmed Lee has no cardiac abnormalities and no stroke.

On the advice of doctors, Lee will be on medical leave and will resume his duties on Aug. 29.

"I'm glad to report that the doctors think I am OK, but they have advised me to rest," Lee wrote in his Facebook.

Singapore's President Tony Tan Keng Yam updated his Facebook on Monday, saying he had spoken with Lee Monday afternoon.

"PM Lee was his usual jovial self. Glad that he is well," Tan said. The president pointed out that Lee had a busy schedule recently, and the preparation for National Day Rally took a toll on him.
