Osterreich newspaper reports that the 69-year-old has actually been in hospital for 12 days, having flown himself in his private jet from Ibiza to Vienna.
It is believed Lauda's kidneys were affected, following a transplant some years ago.
The Austrian was even in intensive care for a time, but his condition has now improved and he is on a normal hospital ward and expected to be released shortly.
"The doctors say that after this episode, Niki must take his health seriously," a friend is quoted as saying.
