“Supernanny” star Jo Frost revealed she suffers from “life-threatening” anaphylaxis.

The British reality TV personality announced her medical condition in a video posted to her Instagram over the weekend.

“I’ve survived more anaphylactic shocks than I’m prepared to go into detail about right now,” Frost, 55, began in the short clip shared with her fans.

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

Anaphylaxis is a “severe, potentially life-threatening allergic reaction” that can “occur within seconds or minutes of exposure to something you’re allergic to, such as peanuts or bee stings,” according to the Mayo Clinic.

Symptoms can include skin reactions, low blood pressure, constriction of the airways, nausea, dizziness and fainting. The condition — which can be life-threatening and stop a person’s breathing or heartbeat — should be treated with an injection of epinephrine and a follow-up trip to an emergency room.

“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,” she claimed.

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

The parenting expert expressed that she is “unapologetic” about her health struggle, noting that she is not going to let it “define” her.

“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,” Frost explained before pointing out that she isn’t looking to receive any “special” treatment and just wants to get “the same dignity and attentiveness as [her fans] just showed others.”

She also asked that people educate themselves on the condition, as she doesn’t want any “mumbling insults” from “ignorant” people.

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

Frost added in the caption of her post that people with anaphylaxis need “compassion” and “empathy.”

“Give me a 💯 and share your thoughts if you want to,” she encouraged. “To my parents, you gave me the tools and confidence to stand tall so that i may for others. Thank you, I love you ❤️.”

In the comment section of her post, Frost was also forced to shut down the rumors that she’s also been diagnosed with Parkinson’s.

When someone asked her if she suffered from tremors, she wrote, “No. Good there, as I mentioned in previous reply it was me comforting myself being very vulnerable about my traumatic experiences. Thank you for your concern 😊.”

Frost rose to fame in the UK in 2004 as the star of “Supernanny.”
