In the 2015 documentary film, Littrell revealed his 2011 diagnosis of vocal tension dysphonia and dystonia. He continues to work with a therapist to help improve his condition. Religious beliefs A devout Christian, Littrell has stated he believes it is the duty of Christians to be open about their faith, saying, "I think as Christians we need to join hands and mount up together and lift God up and talk about our faith publicly and talk about all of the things God has done for us in our life to touch other people." Littrell, who has been born again since the age of 8, has said that he attributes his success in life to God, and that his faith has always been "the utmost important thing" in his life.
