Deborah Norville has indeed undergone plastic surgery. However, unlike most media personalities, Deborah had to undergo surgery for reasons other than cosmetics.
Deborah has been struggling with her health for a very long time. She had to undergo a hazardous surgery that included removing parts of her thyroid gland.
Not only was the risk concerning Deborah’s plastic surgery related to various hormone-related complications that might arise from removing parts of the thyroid gland, but it also threatened her ability to speak.
The nerves of the vocal cord are intricately interlinked to the nerves of the thyroid gland. Hence, any complications in the surgery could risk Deborah losing her ability to speak.
