• Hailey Bieber posted a photo of her stomach saying she's not pregnant but has an ovarian cyst.
• The cyst is "the size of an apple," Bieber wrote on her Instagram story, and it's not her first one.

Hailey Bieber posted a photo showing her stomach on Instagram, saying she's not pregnant but has an ovarian cyst "the size of an apple."

The model, 26, posted a selfie on her Instagram story on November 28, and said she doesn't have endometriosis or PCOS (polycystic ovarian syndrome), which are both associated with cysts. She said she has had ovarian cysts a few times in the past and "it's never fun."

"It's painful and achey and makes me feel nauseous and bloated and crampy and emotional," Bieber, who has 49.3 million followers on Instagram, said.

Endometriosis is a condition where tissue similar to the lining of the womb grows in places such as the ovaries and fallopian tubes. PCOS is a condition that affects how the ovaries work, with symptoms including irregular periods and excess facial hair.

Ovarian cysts are fluid-filled sacs which develop on an ovary. Most ovarian cysts form as a result of the menstrual cycle.

They are very common, do not usually have any symptoms, and usually go away within months on their own, according to the NHS. A bloated or swollen stomach can occur if an ovarian cysts rupture, though.

This is not the first time Bieber has been open about her health issues.

In March 2022, she said she suffered a small stroke caused by a blood clot, as Insider's Anna Medaris reported.

Bieber wrote on Instagram that she had been eating breakfast with her husband, the singer Justin Bieber, when she started having "stroke-like symptoms" and was taken to the hospital," Insider's Gabi Stevenson reported.

Doctors discovered a small blood clot which caused her lack of oxygen.
