Missy Elliott - Missy Elliot Has Thyroid Disease

In 2008 the Work It hitmaker was diagnosed with Graves' disease - a disorder which affects the thyroid - and she admits the symptoms came on so fast, she almost lost her ability to do everyday things like drive and write.

She tells People magazine, "I was (driving and) trying to put my foot on the brake, but my leg was jumping. I couldn't keep the brake down and almost crashed... I couldn't write because my nervous system was so bad - I couldn't even use a pen."

And after suffering a slew of other side effects, including hair loss and mood swings, Elliot turned to radiation - which ultimately improved her condition.

She adds, "I'm 30 pounds (13.6 kilograms) lighter because I've been exercising. My thyroid is functioning, so I haven't had to take medication in about nine months. (But) you live with it for the rest of your life."
