Apple Inc.'s CEO Steve Jobs says he is taking a medical leave of absence until the end of June.
Jobs told employees in an e-mail that his health issues are more complex than he thought.
Last week, Jobs announced he had a hormone deficiency that had caused him to dramatically lose weight.
Apple's chief operating officer, Tim Cook, will take over Jobs' responsibilities while he is on leave.
