Erin Moriarty Opens Up About Her Graves' Disease Diagnosis

In a candid Instagram post on June 14, 2025, Erin Moriarty, known for her role in Amazon Prime's hit series "The Boys," disclosed her recent diagnosis of Graves' disease, an autoimmune disorder affecting the thyroid gland. At 30 years old, Moriarty reflected on her health struggles, emphasizing the importance of recognizing symptoms and seeking timely medical attention.

Graves' disease, characterized by the overproduction of thyroid hormones (hyperthyroidism), can lead to a range of symptoms including fatigue, anxiety, and rapid heart rate. According to the Cleveland Clinic, this condition affects approximately 1 in 200 individuals, particularly women aged 30 to 50.

In her post, Moriarty wrote, "Autoimmune disease manifests differently in everybody. Your experience will be different from mine. Perhaps greatly, perhaps minutely." She highlighted her initial misattribution of symptoms to stress and fatigue, which delayed her diagnosis.

"Within 24 hours of beginning treatment, I felt the light coming back on," she shared, underscoring the effectiveness of early intervention. Moriarty's experience is echoed by many who suffer from similar conditions, reinforcing the message that individuals should not dismiss their health concerns. As she noted, "If yours is dimming, even slightly, go get checked."

Moriarty's revelation comes nearly a year after fellow actress Daisy Ridley shared her own struggles with Graves' disease. In an August 2024 interview with Women's Health, Ridley described her symptoms, including fatigue and a racing heart, which resonated with Moriarty's experience.

Dr. Emily Carter, an endocrinologist at Johns Hopkins University, explains, "Graves' disease can be particularly challenging to diagnose due to the overlap of symptoms with other conditions. Early recognition and treatment are critical to managing the disease effectively." Dr. Carter emphasizes the importance of awareness and education regarding autoimmune disorders.

The impact of Moriarty's announcement extends beyond personal health; it brings attention to the broader issue of autoimmune diseases and their prevalence in society. According to a report published by the American Autoimmune Related Diseases Association, it is estimated that 50 million Americans are affected by autoimmune conditions, highlighting a significant public health concern.

While the entertainment industry often portrays health issues superficially, Moriarty's openness about her struggles encourages dialogue about the importance of mental and physical well-being. Through her platform, she aims to destigmatize autoimmune diseases and inspire others to prioritize their health.

As awareness grows, experts advocate for more research and resources dedicated to understanding autoimmune diseases. Dr. Sarah Johnson, a health researcher at the University of California, San Francisco, notes, "Increased funding for research could lead to better treatment options and support systems for those affected by autoimmune disorders."

Moriarty's journey underscores the significance of advocacy and education in the fight against autoimmune diseases. As she concludes her post, she reminds others, "You deserve to be comfy. Shit’s hard enough as is." This message resonates deeply in a society where mental health and physical well-being are often overlooked. As discussions surrounding autoimmune diseases continue, the hope is that more individuals will feel empowered to seek help and share their stories.

In summary, Erin Moriarty's candid revelation about her Graves' disease diagnosis serves as a crucial reminder of the importance of recognizing health symptoms and advocating for oneself. Her experience sheds light on the significant impact autoimmune diseases have on individuals and communities, encouraging broader discussions around health awareness and treatment options.
