"Two and a half months ago, just before a show in Dallas, I lost most of my hearing. Although I can still hear a little, one on one, and on the phone, I can't hear music well enough to sing. The lower frequencies distort violently making it impossible to find pitch."
Lewis, best known for his hit "Power Of Love" from the 'Back To The Future' soundtrack, said he visited a number of clinics "hoping to find an answer" to his symptoms.
"The doctors believe I have Meniere's disease and have agreed that I can't perform until I improve. Therefore the only prudent thing to do is to cancel all future shows.
"Needless to say, I feel horrible about this and wish to sincerely apologise to all the fans who've already bought tickets and were planning to come see us. I'm going to concentrate on getting better and hope that one day soon I'll be able to perform again," he added.
Meniere's disease is a disorder where a person experiences episodes of vertigo and fluctuating hearing loss.
