Actress Camilla Luddington, known for playing Dr. Jo Wilson on “Grey’s Anatomy,” recently shared her experience with Hashimoto’s disease. She told her story when she was interviewed by Dr. Tara Narula on Good Morning America. The pretty brunette wowed as she arrived for MPTF NextGen Annual Summer Party charity fundraiser in Los Angeles on June 22, 2025. There, she opened up to millions about her wellness journey.
After starring in a number of films, Luddington joined the cast Grey’s Anatomy in 2012. Since that fateful day, she has cultivated a voracious fanbase. When she started getting unusually fatigued, she had the idea to get bloodwork done and thought that something wasn’t right and needed medical attention. The results gave us a definitive diagnosis of Hashimoto’s disease, an autoimmune disorder that attacks the thyroid.
When talking about her diagnosis, Luddington said after receiving the news she felt a wave of relief wash over her. She added, “Once I knew how prevalent it was, it stopped being scary. Truly, the first thing I felt was relief.” This sentiment hits home for so many people who have to deal with the aftermath of chronic health conditions.
The incidence of Hashimoto’s disease is particularly high among women, four to ten times more likely than men. It is known to be the number one cause of hypothyroidism, which affects an estimated 5% of the American population. The National Institutes of Health’s National Institute of Diabetes and Digestive and Kidney Diseases provide detailed information on the condition. Most importantly, they unpack its implications and meaning in clear, digestible terms.
After being diagnosed, Luddington started necessary medication to save her life and experienced dramatic, life-changing benefits to her health. She urged others to tell their stories with the aim of helping those going through the same struggles. She hopes that as you are taking this journey too, you will be just as confounded as she is. Which is why she had hoped to have people on board with her from the start.
Here’s Tania’s diagnosis story told for the first time on the Call It What It Is podcast. The new show is co-hosted by her “Grey’s Anatomy” costar, Jessica Capshaw. Her goal was to network with specialists and increase awareness of Hashimoto’s disease. I don’t just want to talk to scientists and doctors. I want to get information from them and get the information out there. She said that telling a story or disclosing a diagnosis allows other people to feel less alone. Mostly, it creates a feeling of place and belonging to a community.
Luddington is an active participant in her health journey. Her candidness is a beacon for others who are battling the same obstacles. Her tireless advocacy reminds us all to be aware and supportive of the 24 million Americans living with an autoimmune disease.
