Christina Applegate’s daughter shares own heartbreaking diagnosis

Christina Applegate is currently battling MS and now her teenage daughter has shared her own diagnosis.

It turns out Christina Applegate’s daughter, Sadie, is fighting her own health battle amid her mother’s tough battle multiple sclerosis diagnosis.

“I have something called POTS,” the 13-year-old revealed during an episode of the MeSsy podcast.

POTS is a condition that causes a number of symptoms when you transition from lying down to standing up, such as a fast heart rate, dizziness and fatigue.

While there’s no cure, several treatments and lifestyle changes can help manage the symptoms.

“I have no clue what it actually is but it’s something to do with the autonomic nervous system and it affects my heart. When I stand up, I get really, really dizzy and my legs get really weak and I feel like I’m going to pass out.”

Sadie shared that she has fainted and even gone unconscious before, but that doesn’t “usually” occur.

“That’s only on really bad days when it’s hot out,” she shared on the podcast.

While the teenager only received her diagnosis a few months ago, she’s had to live with POTS for a “long time.”

“Last year, in sxith grade, I would go to the nurse multiple times a day for it because I always felt like I was going to pass out,” she said. “In class, if I were to stand up then I would be like, ‘I have to go to the nurse. I can’t do this.’ Or I’ll be in PE, and I’ll be like, ‘I have to go to the nurse’.”

Applegate, 52, then went on to share that she was left feeling “really guilty” because for a long time she had no idea her daughter was actually suffering with an illness, and instead chalked her issues down to being a teenager.

“She wears layers of clothes on 90 degree days and she hates PE — sorry school, not a big fan of PE or physical things,” the actress explained.

“I was like, ‘Oh, I kind of felt that way too.’ I feel so horrible that we didn’t pay attention to it.”
