Vicki Gunvalson is on the mend.

The Real Housewives of Orange County star checked out of the hospital on Friday following unexplained internal bleeding.

"I'm doing much better," Gunvalson, 48, tells UsMagazine.com. She explains: "Doctors performed a colonoscopy and found several ulcers in the colon that they were able to fix and stop the bleeding."

By her side at the hospital: daughter Briana (who's a nurse) plus husband Donn. She filed for divorce from Donn earlier this month after 16 years of marriage.

The hard-working insurance agent plans to go back to work on Monday.

Over the weekend, she thanked fans and friends on Facebook for their prayers and support.
