According to the Presidency's official spokesman,
"The President is the one who can release his own health status. The day he left, we still spoke. He didn’t tell me ‘this is my condition’. He told me he was going to rest and he would do medicals and that was included in the statement we released.
"I am sure it will get to a point when the President has to disclose the status of his health if it needs to be disclosed. If it’s something serious enough to disclose, I am sure he will disclose it.
"So, Mr President can take the time he desires and when his doctors give him a clean bill of health, he then can return home."
