Tom's wife Sandra Araya, posted a new message on her Facebook account stating:

"Tom was suffering from vertigo due to extreme dehydration and lack of rest, our doctor is in the process of getting the results on the test that were ran (major time zone difference and being the weekend has held up those results). Hopefully there will be nothing more to add after the results are returned."

Tom was hospitalized on sunday which led to the cancellation of Slayer's apperance at Sydney's "Soundwave Festival".

Update #1: The organizers of Australia's Soundwave festival have released the following from Tom Araya:
"Sorry I couldn't make the Sydney festival show. I am feeling much better and look forward to performing in Melbourne on March 4."
