Did you know that 1 in 3 women in France experiences heavy or very heavy periods? Combined with a plus-size body type, managing periods can become a real challenge.
Plus-size women and/or those with heavy flow often feel invisible in the period product market. Standard pads and tampons overflow too soon, poorly fitting elastics leave painful marks, and the fear of leaks dominates every day.
But it’s not inevitable. The plus-size heavy-flow menstrual panty can be especially helpful for these women. The key? A design made both for varied body types (not just size 36) and for intense flows.
A heavy flow is more than 80 ml of blood per cycle, the equivalent of 5 size-3 tampons per day. This is often linked to endometriosis, fibroids or a copper IUD, and affects 18% of women of childbearing age. The causes of heavy, intense periods are very diverse.
Disposable products, designed for medium flows, simply don’t meet these needs. **Disposable pads** shift around and saturate quickly. Tampons leak.
In addition, toxic shock syndrome linked to tampons and irritation from plastic-backed pads add health risks to everyday discomfort.
Why do most standard products fail for plus-size bodies? Here are the recurring issues:
The Louloucup plus-size heavy-flow range includes 6 different models, from 2XL to 5XL, at affordable prices, made from GOTS-certified organic cotton, Oeko-Tex Standard 100 certified, and free of PFAS.

Louloucup period underwear is perfect for very heavy flow (Clara, Mathilde, Liv, etc.). You can also consider a menstrual cup, which collects blood very effectively and hygienically.
This may be due to improper care: using fabric softeners, greasy soaps (like Marseille soap) or high temperatures. Tumble drying or drying near a heat source also weakens the materials. To preserve its absorbent power, rinse in cold water, wash at 30–40°C without harsh products and let it air dry. With proper care, a Louloucup brief lasts 5 to 7 years.
