3. There are A LOT of different symptoms, including anxiety and sweating.
This condition can cause a bunch of symptoms that could be mistaken for other problems, including anxiety, irritability, abnormal periods, increased sweating, tremors, and more.
“The dominant symptoms can be a racing heartbeat, increased perspiration, diarrhea, increased anxiety, weight loss, and heat intolerance,” says Smith, who is also a professor of internal medicine at the University of Michigan Medical School in Ann Arbor. “People often feel hot when others around them are comfortable or even cold.”
Other symptoms are shortness of breath, muscle weakness, fatigue, high blood pressure, difficulty sleeping, and chest pain. Eye problems can also be an issue, such as tearing, light sensitivity, and swelling and inflammation of the eyes causing redness, double vision, pain, and a gritty feeling.
4. Williams fainted on her show in November, and it may have been related to her diagnosis.
At the time, she attributed the episode to dehydration, and some people even doubted it was real.
“A lot of people thought that was a joke — me fainting on my set. No, that was not a joke,” she said on her show. “I’m a tall woman and it’s a long way down. I’m also a woman of a particular age and I’m not trying to break anything, and also I don’t do stunts and jokes for you like that. I don’t need that.”
The combination of symptoms, like heat sensitivity, excess perspiration leading to a loss of fluids, plus a racing heart, could lead to fainting, Smith said, although he hasn’t treated Williams.
5. In 2011, Missy Elliott told People magazine that she almost wrecked her car because condition-related tremors made it difficult for her to brake.
Tremors are a common symptom for people with Graves’ disease, says Smith. “One of those things that I look for in the physical examination is tremors,” he said.
The good news is that, since then, Missy Elliott has said she is doing well and is managing the disease.
