Symptoms of Graves’ disease as Erin Moriarty says she dismissed signs as stress

"Don’t ‘suck it up’ and transcend suffering; you deserve to be comfy."

Moriarty is best known for her work in The Boys, as well as notable roles in Jessica Jones and True Detective.

In 2025, the actress revealed her diagnosis of Graves' disease in a post on Instagram.

"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."

Moriarty went on to explain that she could have got her diagnosis sooner if she hadn't dismissed her symptoms as stress and fatigue.

She said added that once she began treatment, she 'felt the light coming back on.'

"It’s been increasing in strength ever since. If yours is dimming, even slightly, go get checked," she penned.

"Don’t 'suck it up' and transcend suffering; you deserve to be comfy. Shit’s hard enough as is."

What is Graves' disease?

Graves' disease is an autoimmune disease that affects your thyroid. It is the main cause of hyperthyroidism and causes a large thyroid.

The main signs of the condition include irritability, muscle weakness, trouble sleeping, and a fast heart rate.

Those with Graves' disease may also have poor tolerance of heat and suffer from diarrhea and unintentional weight loss.

Other symptoms include eye bulging and thickening of the skin on your shins.

Between 25% and 30% of those with the condition will develop eye problems.

The exact cause of Graves' disease is not yet known, but people are more likely to be affected if there is a family history.

The disease can also be triggered by emotional or physical stress, an infection, or giving birth.

Patients who already have an autoimmune disease also have a higher chance of being affected.
