Robin Roberts Takes Time Off Ahead Of Medical Leave: 'I'm Not Feeling Too Well'

Robin Roberts will be taking more time off from "Good Morning America" than expected, she told viewers on Tuesday.

She announced that she will be leaving for one or two weeks before her medical leave, noting that she was not feeling well. Roberts was recently diagnosed with MDS, a rare blood and bone marrow disorder, as a side effect of her battle with breast cancer.

"Well, a full disclosure here, I’m not feeling too well," Roberts told viewers, according to the Hollywood Reporter. "In fact I’m going to leave and let you all do the rest of the program on your own. I’m going to take a little time off, just to get some vacay… I'll see you in a couple of weeks."

Last week, Roberts said that she was planning to take medical leave for her bone marrow transplant at the end of August or the beginning of August. She mentioned Barbara Walters, Diane Sawyer, Katie Couric, Kelly Ripa and co-hosts of "The View" as her substitutes during her absence.
