Erin Moriarty, widely recognized for her role as Starlight in The Boys, recently revealed that she has been diagnosed with Graves’ disease, a serious autoimmune condition. In a heartfelt Instagram post on June 12, the 30-year-old actress shared that she had initially misinterpreted her symptoms, believing they stemmed from stress and fatigue. Her message aimed to encourage others to take their health concerns seriously and not dismiss persistent discomfort.
Erin Moriarty Urges Early Diagnosis and Awareness After Her Graves’ Disease Discovery
Moriarty disclosed that she received her diagnosis a month ago. She emphasized that the disease can affect individuals in vastly different ways, and her personal journey highlighted the importance of listening to one’s body. “If I hadn’t chalked it all up to stress and fatigue, I would’ve caught this sooner,” she admitted. The actress stressed that suffering in silence should not be normalized, urging her followers to seek medical attention if something feels off.
Graves’ disease is an autoimmune disorder that targets the thyroid gland, leading to the overproduction of thyroid hormones—a condition known as hyperthyroidism. This hormonal imbalance can affect a person’s energy levels, metabolism, and overall well-being. While it can affect individuals of any age, it is most common among women over the age of 20. Treatment typically helps manage the symptoms, and Moriarty reported feeling noticeably better within 24 hours of starting therapy.
Persevering Through Illness as Erin Moriarty and Daisy Ridley Share Health Journeys
Despite her diagnosis, Moriarty continues to be active in her career. She has played Annie January/Starlight since The Boys debuted in 2019. The show, which has garnered multiple Primetime Emmy nominations, is set to conclude with its fifth season in 2026. Moriarty’s career also includes notable appearances in Jessica Jones, True Detective, and the indie film The Kings of Summer. She will next appear in the horror film True Haunting.
Moriarty’s experience mirrors that of fellow actress Daisy Ridley, who also went public with her Graves’ disease diagnosis in 2024. Ridley, too, initially misattributed her symptoms to work-related stress. Both actresses highlighted a common issue: the normalization of poor health among women, particularly in high-pressure environments. Ridley pointed out that societal expectations often discourage women from voicing their health concerns, reinforcing the importance of advocacy and awareness around autoimmune diseases.
