Managing intense periods with very heavy flow period underwear: Louloucup’s take

The main reason period underwear loses its effectiveness is build-up. This is an accumulation of residues—fats, detergent, limescale, or even clotted menstrual blood—that clog the absorbent fibers.
Detergents containing glycerin, fabric softeners, or even rinsing with hot water that sets the blood can reduce the performance of this technical lingerie and cause leaks.
You can tell underwear is clogged if water beads on its surface, if it no longer absorbs flow as before, or if odors persist. Improper washing practices, such as using too much detergent, insufficient rinsing, or using a tumble dryer that damages the fibers, also contribute to this build-up. Fortunately, this issue is often reversible through specific "deep-cleaning" treatments, restoring the protection’s long-lasting effectiveness.

To reduce heavy menstrual bleeding, it is essential to consult a healthcare professional, whether a doctor, gynecologist, or midwife.
This is the first step to understanding the cause of heavy flow and tailoring treatment. Menorrhagia, or hemorrhagic periods, very rarely resolve on their own and require informed medical advice.
Several approaches can be considered, including medications such as non-steroidal anti-inflammatory drugs, antifibrinolytics, or various forms of hormonal contraception (the pill, hormonal IUD).
In some cases, surgical options may be recommended, particularly to treat fibroids or polyps. Ongoing medical follow-up is crucial for experiencing more manageable periods.

Heavy periods are often a personal perception of a strong flow, whereas haemorrhagic periods, known as menorrhagia, are a medical condition defined by specific criteria.
A menstrual haemorrhage is characterised by blood loss of more than 90 ml per cycle or bleeding that usually lasts more than 7 days, making it difficult to manage with standard protection.
Unlike simply heavy periods, menorrhagia often comes with more severe symptoms: numerous large clots, intense fatigue that can lead to anaemia, dizziness or stronger abdominal cramps.
These symptoms significantly affect quality of life and can cause physical discomfort and anxiety. If you notice these signs repeatedly, it’s advisable to see a doctor, as menorrhagia can be a symptom of underlying issues such as hormonal imbalances or uterine problems.

For very heavy periods, choosing a menstrual cup can be a really smart move. It is important, however, to pick a model that suits your needs.
Standard cups hold around 20 to 30 ml, which may not be enough for a very heavy flow. It’s therefore recommended to go for larger cups (size L or XL), which hold more than 30 ml. Some brands offer models that can hold up to 50 ml, giving you longer‑lasting peace of mind, even on your heaviest days.
It’s also important to choose a size that fits your anatomy to avoid leaks: a cup that’s too big might not open properly. For truly haemorrhagic flows, menstrual discs can be an even more effective alternative, as their capacity can reach up to 80 ml, offering a simple, effective and long‑lasting solution for optimal protection.

The best period underwear for heavy flow stands out thanks to its high absorbency, often equivalent to 5 regular tampons, and its multi-layer technology, usually featuring three absorbent layers or double absorption. Its absorbent zone is extended, coming up high enough at the front and back to prevent leaks, even at night or when you’re on the move. It’s a game-changing choice that lets you rediscover the pleasure of everyday gestures and an unparalleled freedom of movement. These panties are designed to stay effective for a long time, and can be worn for up to 12 hours without any feeling of dampness, bad odours or a “diaper” effect. They are often antibacterial and moisture-wicking, made from safe, certified materials (such as Oeko-Tex organic cotton) and free from toxic substances.
