“Star Wars” actor Daisy Ridley has been diagnosed with an autoimmune disorder that can come with serious consequences: heart failure, stroke and thinning bones, just to name a few. With more than 3.3 million Americans affected by the disease, she’s hardly alone.

The “Star Wars: The Force Awakens” star revealed during an interview with Women’s Health that she was diagnosed with Graves’ disease in September 2023. Ridley was suffering from bouts of hot flashes and fatigue after filming “Magpie.” That’s when her doctor encouraged her to see an endocrinologist.

“I thought, ‘Well, I’ve just played a really stressful role; presumably that’s why I feel poorly,’” she told the news outlet. It wasn’t.

Speaking to the specialist, she explained she had a racing heart rate, fatigue, hand tremors and was losing weight unexpectedly. “Tired but wired” is how the doctor explained the disease to her.

According to the National Institute of Diabetes and Digestive and Kidney Diseases, Graves’ disease is an autoimmune disorder that can cause hyperthyroidism. The thyroid, which lies near your voice box, creates hormones that control the body’s energy usage. That’s why an overactive thyroid can lead to a wide variety of health issues, including in the heart.

It affects roughly 1% of people in the United States and is responsible for 80% of all hyperthyroidism cases. The disorder is more common in women, people over 30, those with a family history of the disease and people with other autoimmune disorders.

Ridley — a native of Westminster, London — is 32 years old. In the U.K, as of October 2023, the disease affects up to 1.6% of women.

Common symptoms include weight loss (despite an increased appetite), irregular heartbeat, irritability, fatigue, muscle weakness and hand tremors. But more than a third of patients also develop an eye disease: Graves’ ophthalmopathy.

A result of the body’s immune system attacking the eye muscles, symptoms often include bulging, and irritated and puffy eyes, as well as blurred vision, light sensitivity and pain.

“Researchers aren’t sure why some people develop autoimmune disorders such as Graves’ disease,” the institute reported. “These disorders probably develop from a combination of genes and an outside trigger, such as a virus.”
