The Real Housewives of O.C. star Vicki Gunvalson was hospitalized Thursday after experiencing gastrointestinal problems.
Now, a day later, the Bravo reality star tells PEOPLE, doctors still haven’t figured out what’s wrong with her – or what is causing her to bleed internally.
“I’m still in the hospital and we still don’t know why I’m bleeding internally yet,” Gunvalson said in an email Friday.
Doctors are already taking further action to diagnose the ailment. “I am having a colonoscopy so hopefully that will give us some indication,” she says.
