Erin Moriarty reveals Graves’ disease diagnosis
On June 14, 2025, the actress took to Instagram to announce her diagnosis in an emotional post to remind people to watch out for their health and not ignore repetitive symptoms.
The actress wrote:
"Autoimmune disease manifests differently in everybody/every body. Your experience will be different from mine.”
She added:
“My experience will be different from yours. Perhaps greatly, perhaps minutely. One thing I can say: if I hadn’t chalked it all up to stress and fatigue, I would’ve caught this sooner.”
Erin Moriarty posted screenshots of text message exchanges with her parents, who wrote to her on or about May 9, indicative of her declining health.
In one of the messages sent to her mother, she wrote that she felt like :
"I'm serious; I really, really need relief, I feel nauseated tonight. I feel so s--- and removed from who I am. I can't live like this forever. Or that long."
After beginning treatment, she updated her father:
“I already feel a world of difference. Damn, this is how I’m supposed to feel? I’ve been missing out!”
Erin Moriarty states that her condition improved after 24 hours of starting her treatment. She said she could feel the “light coming back on” after weeks of being emotionally and physically in darkness.
As noted by the Mayo Clinic, Graves' disease can result in fatigue, increased irritability, sudden weight loss, hand tremors, and even visible changes to the skin color.
By opening up about her situation in an honest Instagram post, Erin Moriarty encouraged individuals to look after their health and visit the doctor when something seems amiss. She further managed to raise awareness about the necessity of early diagnosis and treatment.
