Jo Frost is opening up about being diagnosed with a life-threatening health condition.

In a recent Instagram video, the star of the hit early-2000s ABC reality show Supernanny revealed she has anaphylaxis, as she urged others to be more compassionate toward those dealing with the condition.

“I’ve survived more anaphylactic shocks than I’m prepared to go into detail about right now,” the 55-year-old shared in the clip.

“I have anaphylaxis, a life-threatening medical condition to certain foods that will compromise my body so horrifically to the point of hospitalization,” she added.

Per the Cleveland Clinic, “Anaphylaxis is when you have a severe allergic reaction. Most commonly, it happens after you eat certain foods or get stung by an insect. Going into anaphylactic shock can be life-threatening.”

Frost added in the video, “Absolute millions of my community around the world, children and adults, live cautiously and anxiously navigating this journey with not nearly enough compassion, education and empathy from those who do not.”

“Today, everyone will know someone or someone who knows of one with anaphylaxis. If you ignore the severity of this medical condition, it’s as bad as shoving a loaded gun in my face,” she continued, insisting that she’s “unapologetic” for her medical condition.

“I did not ask for it, and it does not define who I am and the impact that I make in the world daily,” she said. “But it does impact how I live my life daily, like the precautions I take, the energy I have to use to discern with hypervigilance.”

She criticized those in restaurants who might not pay enough attention to her condition, as well as things such as the “it may contain” labels on food.

“By the way, I speak on behalf of those who also have celiac disease, too, because we are all not faddy eaters. I’m not looking to be treated special, I’m looking to be treated with the same dignity and attentiveness as you just showed others,” Frost said in the clip.

The TV personality added that she doesn’t want “mumbling insults” or “passive-aggressive” comments from people who might not understand her condition, and urged everybody to be open to learn more about it and educate staff, among other things.

“Get curious and learn more, because really, as mentioned before, we all know someone,” Frost insisted.

Frost is best known for starring in Supernanny from 2005 to 2011. She was also the star of the British version for many years, earning a reputation for her no-nonsense approach and heartfelt empathy for struggling families.

In a 2020 interview with PEOPLE, the professional nanny explained why she chose her career path.

“People told me I was good with children,” Frost said. “It was just always very natural for me to hold babies and be around children; it’s just part of my DNA.”

Almost a decade after the last Supernanny episode aired, Lifetime renewed it for an eighth season with Frost at the helm once again. A batch of 20 episodes premiered in 2020 and focused on helping parents with modern struggles like internet usage, balancing complicated schedules and video games.
