Grey's Anatomy Stars Share Real-Life Health Battles Off-Screen
Grey’s Anatomy viewers have consistently tuned in year after year to witness the cast confront some of the most challenging medical crises — and, as a result, have seen the show’s performers grapple with their own health concerns in real life.
In January 2026, fans were shocked by the news that Steven W. Bailey had received a diagnosis of Congenital Myasthenia Syndrome (CMS).
“Speaking of difficulties, it’s quite peculiar, but it turns out I have a rather uncommon inherited disorder affecting the muscles and nerves. Strange, isn’t it? It’s called Congenital Myasthenia Syndrome, or CMS,” Bailey, who portrayed Joe the bartender on the popular series for several years, shared via X at the time.
“CMS is a genetic illness that interferes with the communication between the brain and the muscle at the ‘nerve/muscle connection’… or whatever physicians refer to it as,” he added.

Bailey isn’t the only member of the Grey’s cast who has been candid about their health struggles and diagnoses. Continue reading to learn more about what the cast has experienced behind the scenes.
Kate Walsh
During a 2017 appearance on The Today Show, Walsh revealed she had been diagnosed with a brain tumor two years earlier in 2015.
“I was exhausted,” she explained. “But I’d just finished a show, ‘Bad Judge,’ and I was starring in it and also serving as an executive producer, so it wasn’t unusual to be completely drained. So I thought I had simply overextended myself.”
However, she didn’t regain her energy, so Walsh consulted with her doctor after she began noticing memory problems.
“I couldn’t locate my words; I couldn’t retrieve my thoughts. It was subtle at first, then it became quite noticeable rather quickly,” she explained. Ultimately, doctors discovered a lemon-sized tumor in her brain.
“I was incredibly fortunate that it was benign, and they were able to remove it entirely,” she concluded.
Camilla Luddington
While speaking with People in October 2025, Luddington revealed she’d been diagnosed with the autoimmune disorder Hashimoto’s disease earlier that same year.
“It’s still new to me,” Luddington told the publication at the time. “I received the diagnosis at the beginning of summer, so I’m relatively new to this journey. I am taking Levothyroxine, which is a thyroid medication, and I can tell you that many things have changed.”
She continued, “I feel like I have significantly less inflammation; I was very swollen all the time, without knowing why I was so tired. I wasn’t exercising. I hadn’t attended a workout class in years, and I’m now back at Barry’s bootcamp lifting weights. So I feel more like myself. I feel like I have more energy for work, for my family.”
Luddington also shared details about her symptoms.
“One thing that I couldn’t understand was I experienced a lot of brain fog, and now I understand that when your thyroid is somewhat unstable, that’s what that can feel like,” Luddington recalled. “The fatigue associated with brain fog. So simply being able to be present with those on set, with my family, is a significant difference.”
James Pickens Jr.
In November 2025, Pickens Jr. told Black Health Matters that he had been diagnosed with prostate cancer.
“It’s not the kind of news anyone desires to hear, but to be honest, prostate cancer has been prevalent in my family,” the actor said. “My father had it. He had many brothers; several of them had it. I would have been surprised if I hadn’t developed it.”
Fortunately, he has examples within his family that demonstrate the disease can be overcome.
“I have a 90-year-old first cousin, who is still alive, actually; he had it,” he explained. “His son has it. A couple of his brothers had it. As far as I know, none of them have succumbed to it.”
Steven W. Bailey
In January 2026, Bailey shared his own diagnosis of Congenital Myasthenia Syndrome (CMS).
“Speaking of difficulties, it’s quite peculiar, but it turns out I have a rather uncommon inherited disorder affecting the muscles and nerves. Strange, isn’t it? It’s called Congenital Myasthenia Syndrome, or CMS,” he announced via X.
“CMS is a genetic illness that interferes with the communication between the brain and the muscle at the ‘nerve/muscle connection’… or whatever physicians refer to it as,” he also explained. “There are billions of these connection points in a body, and an increasing number of mine seem to be malfunctioning. Troublesome, little things — wouldn’t you agree?”
He continued, “The point is: my muscles aren’t clearly receiving all my brain’s instructions to perform all the wonderful things muscles are meant to do. It’s a setback. The result being that my hands, arms, and legs tire more quickly than they should, which makes them weaker than, well… expected. Sustained repetitive movements are particularly challenging and can cause my muscles to temporarily tighten and shut down.”
Eric Dane
Dane announced he had been diagnosed with ALS in April 2025.
“I have been diagnosed with ALS,” the actor said in a statement to People. “I am grateful to have my loving family by my side as we navigate this next chapter.”
He also expressed his intention to return to work on the hit HBO series, Euphoria, for the show’s final season.
“I feel fortunate that I am able to continue working and am looking forward to returning to the set of Euphoria next week,” the statement continued. “I kindly ask that you give my family and I privacy during this time.”
ALS stands for amyotrophic lateral sclerosis. The condition, also referred to as Lou Gehrig’s disease, is a nervous system disease that affects nerve cells in the brain and spinal cord, according to the Mayo Clinic. There is currently no known cure.
