It is reported that one in 10 women of reproductive age in the UK are battling endometriosis - a staggering figure when you consider that women account for more than half of the UK's population.
In response to the growing number of sufferers, an online retailer has created a special card to convey your symptoms to strangers should you be having an endometriosis flare-up and need emergency assistance.
Being an invisible illness, endometriosis, which does not carry any outward signs, can be utterly debilitating to those battling it.
Even more so when trying to articulate your symptoms; which range from chronic fatigue to nausea and searing abdominal pain, to someone you don't know.
However, Etsy shop Cure Up is hoping to turn that around by selling the purse-friendly card, which costs less than a pound, to help get your point across.
The card reads: "I'm having an endometriosis flare.
"The person holding this card suffers from Endometriosis, a severe and very painful disease. They are probably having a flare right now which means they are in immense pain.
Adding: "The holder of this card needs a quiet place to rest and preferably on a soft surface while they recover. Please allow the cardholder to use your restroom as it is a medical emergency.
"Your kindness and cooperation would be much appreciated."
While the second side shares the different symptoms the endo sufferers experience: "Excessive bleeding, extreme pain in the abdominal area, intense lower back pain, pain with bowel movements and urination, extreme fatigue and nausea."
Describing the product on their shop, they wrote: "If you're having an Endometriosis Flare, it can be difficult to convey the problem to a stranger.
"This card can help get your point across. If you're having a Flare and can't communicate effectively, simply hand this card to a manager or employee so they can try and help you."
The online shop also explains that sufferers of the chronic inflammatory condition can also avail of a free card, although it will take a bit longer to get to you.
One customer who purchased the card is 22-year-old Emily Wilkinson, an endometriosis sufferer, who experiences endo symptoms daily, which can't be alleviated by medicine due to an allergy.
Speaking to Tyla, the Washington-based blogger explained that the card has given her piece of mind: "I have severe endometriosis, pelvic pain and am allergic to most medicine. During a flare up, it becomes a medical emergency.
"Most people have been understanding. I carry the card with me to my university classes, to work, when I'm out running, at the store, just about everywhere.
Adding: "I also have a medical ID bracelet as well that lists my husband's contact information and my condition."
Emily, who has been battling the disease for more than a decade, recommended the card to fellow endo sufferers and said that it makes her feel "safe".
"It's definitely helpful and I recommend it to anyone who has endometriosis," she continued. "If anything, it give a piece of mind. Some woman only get endometriosis symptoms during their periods, unfortunately I experience daily symptoms.
"Having a card that I can quickly show and ask for help, makes me feel safe and more functional."
