Lamar Odom has undergone 2 emergency surgeries, and it has taken a toll on his mind ... TMZ has learned.
We're told the procedures involved chest issues, but we do not know if it's connected to his lungs or heart.
Our sources say the surgeries have put Lamar in "a fragile mental state." We're told he's emotional and at times, very upset.
We're told doctors have locked the doors on all visitors except Khloe while Lamar deals with the immediate physical and mental issues.
