Did Makena White Have a Health Issue?

Makena’s family, friends and Jake have not confirmed whether she was living with a health issue. However, she previously described herself as a “tachycardic,” which likely referred to tachycardia: a heart condition that causes a rapid and/or irregular heartbeat.

On June 2, 2025, Makena tweeted, “We’re dialled #GolfsLongestDay,” before following up in a separate tweet that read, “By dialled I mean tachycardic,” alongside a photo of her Apple Watch’s heartbeat detector. The image showed that Makena had a BPM of 133 at that moment.
