While our favorite celebs may appear to be perfectly fit and healthy on the outside, you'd be surprised to find out what kind of severe illnesses they've suffered from, or are currently suffering.
After experiencing a mild case of kidney failure in early 2012, Nick was diagnosed with a form of lupus — a chronic, autoimmune disease that could affect any part of the body. Grammy award-winning R&B songstress Toni also suffers from a form of lupus, which she was diagnosed with at just 15-years-old.
'The Biggest Loser' trainer may appear perfectly healthy at first glance, but Jillian actually suffers from polycystic ovary syndrome, a condition that causes cysts to form on the ovaries (leading to fertility complications) and irregular menstruation, as well as endometriosis, which results in irregular bleeding and pain.
While the famed actor originally went on record to state he was suffering from "throat cancer," it was revealed later on that Michael actually had tongue cancer (generalized under oral cancer) — which he may have contracted through oral sex. Currently, Michael is fully recovered. Here's hoping he stays cancer-free!
Yolanda has been battling Lyme disease for the past three years, which has affected her ability to read or write. While the disease (spread through tick bites) is treatable if identified early on, 'The Real Housewives of Beverly Hills' star suffers from more severe symptoms due to a late diagnosis. We wish you a speedy recovery, Yolanda!
Pamela's known for her fit and toned body, so would anyone be able to guess the model and actress actually suffers from Hepatitis C, an infectious disease affecting the liver? Nevertheless, Pam's not bothered by it and is intent on living out her life as healthy as possible!
