Olympic gymnast Simone Biles revealed on social media Saturday that she experienced a serious health scare, describing the incident as "almost dying."

The 29-year-old athlete shared limited details about the experience on her Instagram Stories, calling it unexpected and thanking those who had reached out with well-wishes.

"I'm not one to normally share things like this because I value privacy in today's age," Biles wrote on the social media platform. She characterized the experience as frightening but provided no specifics about the nature of the health incident.

Biles, who is widely regarded as the world's most decorated gymnast, did not elaborate on what caused the health scare or provide details about her current condition. The timing of her husband Jonathan Owens' absence was mentioned in relation to the incident.

The gymnast's post was described as cryptic, offering few details about the circumstances surrounding the health emergency. Biles has not provided additional information about the incident or her recovery since the initial social media disclosure.
