Elizabeth Taylor was taken to hospital earlier this week over symptoms caused by congestive heart failure.
The 78-year-old actress, who underwent heart surgery in October 2009, is being monitored at Cedars-Sinai Medical Centre in Los Angeles.
Her rep said in a statement: "This issue is being addressed. She is currently being kept in the hospital for monitoring.
"Her family and close friends are appreciative of the warm support and interest of her loyal fans, but have asked that people respect her privacy and allow her medical team the time and space to focus on restoring her back to health."
