Robin Roberts updated viewers on the status of her health on Thursday.

Through a post on her Facebook timeline, Roberts wrote that she had been briefly hospitalized after she fell ill during a trip to Key West last week. She pointed out that it was "nothing serious," but that her doctors wanted her admit her to the hospital for a few days. She wrote that she will finish the week resting at home and return to the "Good Morning America" set next week.

After undergoing a bone marrow transplant in September, Roberts returned to the morning show she co-hosts in February. In June 2012, Roberts announced that she had been diagnosed with a rare blood disorder called MDS. She started treatment almost immediately and left the show in late August for a transplant. Since her return, she has participated in the network's coverage of the Oscars and interviewed Michelle Obama. She was also on one of the four covers The Hollywood Reporter released for its annual New York Issue, which names the 35 most powerful people in the media industry.

Read her message to viewers below:

My heart continues to go out to the remarkably strong people of Boston. We stand by you now and always.

It saddens me that I haven't been able to join my colleagues in covering this important story.

Last week, in the middle of my Key West vacation, I began not to feel well. Nothing serious, just under the weather. I contacted my doctors and flew back to NYC. They felt it best to admit me into the hospital for a few days. Seems my young immune system needed a little boost to fight off "opportunistic infections".

My doctors assured me that this was NOT because I was working or doing too much, too soon. It's extremely common, post bone marrow transplant, to have complications. I'm blessed that mine have not been severe.

I'm feeling MUCH better, and will relax at home for the rest of the week. I'll be back on GMA next week...as my sweet momma would say: "Good Lord willing, and the creek don't rise!"

Miss you and bless you..XO

Roboz, who is helping Robin prepare her for her bone marrow transplant, appeared on the program to discuss the medical road ahead. In the coming weeks, Dr. Roboz will help monitor Robin’s health and progress. (AP Photo/ABC, Fred Lee)
