“At 17, I gained 70 pounds in the year, for no reason. There was no explanation for it.”
Pieterse, 27, explained that doctors weren’t able to give her an answer for years despite detailing her ongoing symptoms.
“I never had a regular period ever and I was just always told by gynecologists that I was just young. Like, ‘Don’t worry, it’ll regulate,’” she said.

Eventually, she was recommended to an endocrinologist who finally diagnosed her with PCOS (polycystic ovary syndrome).
“I was like what’s that? I’d never heard of PCOS before. And it’s a disease, it’s not curable, it can be dormant,” Pieterse said.
“And the most frustrating part about this is that it’s fairly easy to diagnose. It’s a hormone imbalance. It’s a hormone disease, and it’s so easy to see because your testosterone or your estrogen will be really high, you’ll have really low vitamin D levels, you’ll be deficient in a lot of things.”
The “Geek Charming” star explained that every person has a different experience with the condition, with some experiencing cysts on their ovaries, gastrointestinal issues, changes to hair growth or weight gain.
“I had a lot of those outward symptoms that everyone could see,” she said.
In 2020, the “Honor List” actress revealed that she was pregnant with her first baby. She and husband Hudson Scheaffer — who wed in 2018 — welcomed their son, Hendrix, that November.
“Just the fact that we were able to get pregnant was such a blessing because with PCOS that made me nervous,” she previously told People.
“A lot of women have infertility issues and so we were expecting more difficulty, so it’s been an absolute blessing that we were able to just get pregnant by ourselves.”
