Brooke Shields Says Her Health Is Fine Following Her Seizure: 'I Didn't Know It Was All About Salt' (Exclusive)

Shields first opened up about her health scare for the cover of 'Glamour' 2023 Women of the Year

Brooke Shields is giving a health update after revealing in September that she'd suffered a grand mal seizure.

"I'm fine," Shields, 58, tells PEOPLE exclusively at the Glamour Woman of the Year Awards in New York City on Tuesday where she was being honored.

"I mean, now my salt is okay," she continues. "I didn't know it was all about salt and they were like, eat potato chips and I'm like, really? I didn't know the serious nature of flooding your system, flooding yourself with the necessary sodium that one needs, and how your kidneys can malfunction. I didn't know. I just kept thinking I was hydrating."

Shields first opened up about her health scare in her Glamour 2023 Women of the Year cover story. She said the seizure occurred before a performance of her one-woman show, Previously Owned by Brooke Shields, at New York City's Café Carlyle, a famed performing arts venue and restaurant.

“I was preparing for the show, and I was drinking so much water, and I didn't know I was low in sodium,” Shields recalled to Glamour. “I was waiting for an Uber. I get down to the bottom of the steps, and I start evidently looking weird, and [the people I was with] were like, ‘Are you OK?' "

Shields also explained that the night of the seizure she left her home, but kept getting asked by her companions if she was “all right” and needed some coffee. She said she “walked" to a "corner” outside and felt discombobulated before heading into nearby N.Y.C. restaurant L'Artusi.

“...I go to the sommelier who had just taken an hour to watch my run-through... Everything starts to go black. Then my hands drop to my side and I go headfirst into the wall,” the actress explained.

She said that was when the grand mal seizure started, describing it to the publication as “frothing at the mouth, totally blue, trying to swallow my tongue.”

“The next thing I remember, I'm being loaded into an ambulance. I have oxygen on. And Bradley f---ing Cooper is sitting next to me holding my hand,” Shields shared.

Ultimately, she said in the story that doctors determined that “low sodium" caused the seizure after she consumed "too much water." "I drowned myself. And if you don't have enough sodium in your blood or urine or your body, you can have a seizure."

Now, that she's aware of what caused the seizure, she tells PEOPLE she's drinking less water than she was before.

Aside from the seizure, Shields also opened up in the Glamour cover story about her body image. After 5 years in the spotlight, Shields says she's tired of focusing on her appearance. “I love food, and I love alcohol, and I love life and I want to be healthy for my heart,” Shields told the magazine.
