March is Endometriosis Awareness Month, and we want to make sure you have everything you need to help us spread the word about endo.
Endometriosis affects 1 in 10 women and those born with a uterus, yet is still widely misunderstood, underdiagnosed, and underfunded. Some people still don’t even know what endometriosis is.
That’s why we’re launching The Bite the Lemon Challenge, a new social awareness campaign to spark conversation around endometriosis. This challenge starts on March 1st, 2026, and is designed to be simple, shareable, and impossible to ignore. Just like the Ice Bucket Challenge, it’s about using a bold, visceral moment to stop the scroll, and turn it into education, empathy, and action.
Biting into a lemon wedge is uncomfortable. Sharp. Unexpected. It makes your face scrunch, your body react, and your nerves light up instantly. That jolt is intentional. For people living with endometriosis, pain often arrives suddenly, intensely, and is frequently dismissed as “normal.” The lemon represents that moment of shock, the pain people are told to push through, and the daily reality many endure in silence.
The lemon represents that moment: the discomfort that hits without warning, the pain people are told to push through, and the reality that so many live with daily. This challenge isn’t about exaggeration. It’s about creating a shared physical moment that helps others feel what’s so often ignored.
“The Bite the Lemon Challenge is important because it takes something that has lived in silence for far too long and puts it directly into the public conversation,” EndoFound’s Social Media Manager Leslie Moser says. Moser created the challenge to spark widespread and real conversation about endometriosis. “Endometriosis has been minimized, dismissed, and misunderstood for generations,” Moser adds. “If a simple bite of a lemon can spark even one real conversation, one earlier diagnosis, or one person feeling less alone, it matters. For me personally, this isn’t just a campaign. It’s lived experience. It’s years of being told pain was normal. It’s watching people I love struggle in silence, myself included. This challenge is about visibility, validation, and finally shifting the narrative.”
As a participant in EndoFound’s Bite the Lemon Challenge, you will be fostering empathy, normalizing talking about pain, and encouraging donations to support our research, education, and advocacy efforts. You will be helping educate people about the disease. You will be giving the endometriosis community something shareable that demonstrates just how hard the disease is, without oversharing or feeling like they are burdening by speaking up. And you will be making the endometriosis community feel so much less alone.
We hope you will join us this March in our mission to spread the word about endometriosis. Good luck!
