Christina Applegate reveals the one terrible MS side effect that’s affected her “more than the disease”

In the high-stakes theater of Hollywood, where image is often treated as the ultimate currency, Christina Applegate has spent decades under a microscope. Yet, as she reveals in her searing new memoir, “You With the Sad Eyes,” the most brutal scrutiny she has faced isn’t from the paparazzi—it’s from her own reflection. For Applegate, the secondary symptoms of Multiple Sclerosis (MS) have staged a coup on her self-image, triggering a battle with body dysmorphia that she admits has often felt more devastating than the neurological disease itself.

A Landmark Crisis: MS by the Numbers

Applegate’s struggle is shared by a staggering number of Americans. According to a landmark study funded by the National Multiple Sclerosis Society, nearly 1 million people in the U.S. are currently living with the condition. As defined by the Mayo Clinic, MS is an autoimmune disorder where the immune system attacks the protective myelin sheath covering the nerves. This disruption of the central nervous system manifests in a wide array of symptoms—from numbness and vision loss to severe mobility issues—often following a volatile cycle of “relapse” and “remission.”

The “Blob” and the Briefing: A Collision of Identity

Diagnosed in 2021, the Emmy-winning actress has become an “honesty missile” for MS awareness. In her book, she pulls back the curtain on the physical transformation mandated by her treatment. Early in her journey, Applegate underwent 15-hour steroid infusions to manage flare-ups—a medical necessity that had immediate, jarring effects on her physique.

“The stability I’d fought so hard for went haywire,” Applegate explains. “Immediately everything just went like a f*cking blob.”

For a woman who came of age on the sets of Married… with Children, the shift from being a global sex symbol to a person with a disability was compounded by Hollywood’s unforgiving standards. Applegate admits to feeling a deep sense of “embarrassment” when looking at recent photographs of herself, convinced that the public gaze has shifted from admiration to a toxic blend of pity and judgment regarding her weight.

“The Good Is Followed by the Bad”

Applegate emphasizes that her distress wasn’t necessarily about being “bigger,” but about the psychological trauma of a woman who had “control all her life” suddenly losing that agency. The struggle became so intense that she avoided looking in a mirror for an entire year.

However, the physical narrative shifted again when severe stomach issues forced her onto a clear-liquid diet. The results were drastic:

• Rapid Weight Loss: Within seven months, she lost more than 50 pounds.
• Muscle Atrophy: Today, she describes her legs as being “tinier than they’ve ever been.”
• Physical Vulnerability: The loss of muscle mass has created a dangerous reality where her bones lack protection if she falls, a constant fear given the mobility issues associated with MS.

The War Within: Dysmorphia vs. Recovery

Despite the chronic pain and the “scary” fragility of her current physical state, Applegate has found a strange, albeit healthier, relationship with food. Yet, she remains candid about the cognitive dissonance that comes with her new frame.

“Once again, the good is followed by the bad: I’ve managed to create a much healthier place when it comes to my relationship with food, only to get out of the shower and see legs that are scary‑looking,” she writes. Even now, she hears a “little voice” in her head praising her for being skinny—a voice she identifies as “the sickness.”

Applegate’s story serves as a raw reminder that for many patients, the war for health is fought on two fronts: the biological battle within the nerves and the psychological struggle with the self. Her final verdict on the voice of body dysmorphia? “She’s not going to win.”
