@tilscience: This one is for my heavy flow girlies ✨🩸 Your period product’s absorbency rating was never tested with blood. It was tested with saline (water, salt, bicarbonate) since the 1980s. And despite what 2023 headlines implied, that hasn’t changed. Manufacturers still use saline today. What did happen in 2023: OHSU researchers ran the first-ever study testing real absorbency with donated blood. Period underwear (marketed for heavy flow) held the least ~1–2 mL. Menstrual discs held the most at 61 mL on average. Tampons, pads, and cups fell somewhere in between. This matters because doctors diagnose heavy menstrual bleeding by change frequency. Wrong absorbency numbers = underdiagnosed anemia, endometriosis, even cancer. We’ve been using the wrong ruler for 40 years, and it’s sitting in patient charts as missed diagnoses right now. More on this, including a company actually fixing it, drops on our YT channel at the end of month.

and do pads not take into account that we sweat and that’s also absorbed???

I had a menstrual cup that had measuring lines on the side to tell me how much I was bleeding. And I KNEW I was bleeding more than normal because I was filling that whole thing up to overflowing several times a day. I took those measurements in millilitres to my doctor and he sounded like he had never heard of a menstrual cycle before beyond the fact that women are supposed to have them

Amy 🛸 :
Pads never absorb the way they're advertised. It takes far too long for it to absorb if it does at all usually it just sits on top. It's because blood is obviously thicker than saline. I don't know who's idea it was that saline is a good idea or why it's still being used. They don't even need to use real blood. They could easily use something else with a more similar viscosity.

Give me $100 a day and I’ll use a diva cup and store all my shark week water 😅 for scientific research only of course!😂😂😂

I absolutely hate using pads but tampons and cups hurt and underwear was too uncomfortable. 😭 I'm happy my period has gotten waaaay shorter the older I get. 🥳

it's why I don't focuse on the absorbency label I focus on the size. as long as it goes from navel to butt crack I'll be fine

Right, I get why they never used human blood, but why not pig blood or cow blood? They already have doctors learn things on pigs why not use that blood?

People with uteruses are put on medications to control their flow based on these “how often to you change” standards. Meds with side effects, and long term health implications.

giving physicians the hard numbers (ml) didn't help them understand either. using cups & discs, you can note how much fluid is lost at each change but because they don't understand what is a normal number, they dismiss it

If men were the ones with menstrual bleeding the standard of health care would be 10+ times better and we might’ve found a way to stop the bleeding all together… can someone sue the companies who but in a false test for criminal negligence and false advertising?

Do we even know what a heavy flow is when the NIH still thinks an average period means 1-2 tablespoons of blood loss?

I would always leak through a super pad within an hour when I was a teenager. I thought there were something wrong with me.

People need to care more about women’s health and change the stigma around periods because if companies won’t even use real blood then Me a 16 year old is going to have to keep using maternity pads that feel like I’m wearing a nappy and that’s not fair at all
