Every minute in the US, a woman needs a blood transfusionbecause of her period.
Heavy menstrual bleeding isn't just inconvenient.
It causes iron deficiency, anemia, debilitating fatigue — and it's massively underdiagnosed.
Quantiflow is the first tool that can measure it.
What Heavy Bleeding Actually Does
It's not just a heavy period. It's your health.
Heavy menstrual bleeding (HMB) affects 1 in 3 women — making it more common than asthma or diabetes in women of reproductive age. But because it's never been measurable at home, millions of women go undiagnosed for years.
The consequences are real:
Anemia & iron deficiency
Chronic fatigue that doctors often misattribute
Brain fog & difficulty concentrating
From sustained blood loss over years
Hair loss
A little-known but common symptom of iron deficiency from HMB
Financial impact
Missed work, medical costs, quality of life
On average, women with HMB wait 5 years before receiving help.
Why It Goes Undiagnosed
It's not because you're not trying. It's because there was no way to measure it.
Without an objective measurement, "heavy" is just a feeling — easy to dismiss, easy to minimize. Doctors defaulted to watchful waiting. Women defaulted to coping.
Quantiflow changes that. It's the first clinically validated, mobile-based system that measures menstrual blood loss objectively — giving both patients and clinicians a number to work with.
