‘The Boys’ star Erin Moriarty reveals Graves’ disease diagnosis, urges fans to go get checked: ‘I felt the light coming back on’

Erin Moriarty has been diagnosed with Graves’ disease.

The 30-year-old actress, who plays Annie January/Starlight on Prime Video’s The Boys, opened up about her recent diagnosis in a June 12 Instagram post. Moriarty, prior to receiving her diagnosis, merely attributed her symptoms to “stress and fatigue.”

“Autoimmune disease manifests differently in everybody/every body,” she wrote. “Your experience will be different from mine. 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.”

Moriarty said she was made aware of her condition a month ago.

“A month ago, I was diagnosed with Graves’ disease,” she wrote. “Within 24 hours of beginning treatment, I felt the light coming back on. It’s been increasing in strength ever since. If yours is dimming, even slightly, go get checked. Don’t ‘suck it up’ and transcend suffering; you deserve to be comfy. S***’s hard enough as is.”

Graves’ disease is an autoimmune disease that affects your thyroid gland. The gland causes the body to make too much thyroid hormone, which can cause a condition known as hyperthyroidism. Anyone at any age can be diagnosed with Graves’ disease, though it is most commonly seen in women over the age of 20.

Moriarty has been starring on The Boys since its debut in 2019. The fifth and final season of the eight-time Primetime Emmy-nominated series is set for 2026. Before playing a superhero, the New York native landed roles on Jessica Jones, True Detective and Red Widow. She previously appeared in the 2013 film The Kings of Summer, and will next be seen in the forthcoming horror film True Haunting.

Star Wars star Daisy Ridley revealed her own Graves’ disease diagnosis in the August 2024 issue of Women’s Health. Like Moriarty, the British actress initially disregarded her symptoms as the effects of playing a “really stressful role.”

“We all read the stats about women being undiagnosed or underdiagnosed and sort of coming to terms with saying, ‘I really, actually don’t feel good’ and not going, ‘I’m fine, I’m fine, I’m fine, I’m fine.’ It’s just normalized to not feel good,” she said.
