Gabor was taken to Ronald Reagan UCLA Medical Center on Tuesday afternoon where doctors performed emergency surgery to repair a “major infection in her stomach” caused by a feeding tube.
According to her husband, Prince Frederic von Anhalt, the 94-year-old actress has been unresponsive since 2 a.m.
In January Gabor had her right leg amputated because of a gangrene infection. In February, she was also treated for pneumonia.
In late March, she was hospitalized for high blood pressure following the death of Elizabeth Taylor.
