Apple C-E-O Steve Jobs is taking a medical leave.
Jobs says the health problem he revealed just days ago is more complex than he originally thought.
You may remember. last week Jobs blamed his recent weight loss on an easily treatable hormone deficiency.
But now, he says he plans to be away from the job until the end of June to focus on his health.
Apple's stock plunged seven percent today after the announcement.
