The beauty recently took to Instagram to share a screen grab of how diabetes management app Dexcom alerts her when she's having a diabetic hypo.

"I still find it frightening when I have a hypo alone as I can go unconscious & I'm still learning that when I'm sick it's different and more difficult to manage," she told her 199k followers on the social media app.

"I'm beyond grateful to have @dexcomuk which alerted my people."

She added: "So the past week my diabetes has been super hard to control due to not being well.

"All I can say is thank god for @dexcomuk alerting my friends and family."

A hypo, according to , is "when your blood glucose level (also called blood sugar) is too low, usually below 4mmol/l".
