Some months ask more of you than others. When your period regularly soaks through pads, stretches on for days, and leaves you wiped out, that is your body asking for a closer look and for some real support.

TLDR: Heavy periods, known medically as menorrhagia, are common and very treatable. Telltale signs include soaking a pad or tampon every hour or two, doubling up on products, passing large clots, and feeling drained. Heavy bleeding often lowers your iron, so tiredness is part of the story. A GP can find the cause and offer real options, from everyday relief to longer-term treatment.
What counts as a heavy period?
Periods vary hugely from woman to woman, so “heavy” is really about what feels heavy for you and what affects your daily life. Still, there are some clear signposts. The NHS describes heavy menstrual bleeding as needing to change your pad or tampon every one to two hours, or using two types of period product together, such as a pad and a tampon at once.
Other familiar signs include bleeding that soaks through to your clothes or bedding, passing blood clots larger than about 2.5cm (roughly the size of a 10p coin), and periods that stretch beyond seven days. If any of this sounds like your normal, please hold on to two things: you are in good company, and effective help exists.
Why is mine so heavy?
Sometimes a clear reason shows up, and sometimes the bleeding is simply heavy for you with the cause staying harder to pin down, which is common and still very manageable. The NHS lists several conditions that can drive heavier bleeding, including fibroids, endometriosis, adenomyosis, polycystic ovary syndrome (PCOS), and pelvic inflammatory disease (PID), an infection of the upper genital tract.
It helps to know the two most common culprits by name. Fibroids are benign (harmless) growths of muscle in or on the womb that can increase bleeding, and adenomyosis is tissue similar to the womb lining growing into the muscular wall, which often brings heavier, achier periods. The NHS groups both among the usual causes, and a scan can tell them apart, so naming them gives your GP a clear thread to follow.
A few other influences are worth knowing. Conditions that affect how your blood clots, such as von Willebrand disease, can make periods heavier, and certain medicines, including some anticoagulants (blood thinners), play a part too. A copper coil can also increase bleeding for some women. This is exactly why a proper conversation with your GP helps so much: the right cause points to the right support.
Life stage matters as well. Many women notice their flow changing in the years around perimenopause, when hormone levels swing, and in the months after having a baby as the body resettles. A flow that shifts with these chapters is common, and a GP can reassure you about what fits your stage and what deserves a closer look.
Picture this. You plan your outfits around your cycle, keep a spare set of clothes at work, and map every long meeting against where the nearest loo is. You set a night alarm to change protection so your sheets stay safe. You have quietly built a whole logistics operation around your period, and you have come to assume this is simply your lot. That ingenuity is impressive, and your body deserves a look from someone who can lighten the load.
The iron link worth knowing
Here is the connection that surprises many women. When you lose a lot of blood each month, your body can struggle to replace the iron that travels with it, and iron is the mineral that carries oxygen around your body. Heavy periods are a very common cause of iron-deficiency anaemia, and the NHS lists anaemia among the things a blood test checks for when bleeding has been heavy. That link helps explain the bone-deep tiredness that often travels alongside heavy bleeding.
The signs of low iron include fatigue that sleep fails to shift, breathlessness on the stairs, a pale look, and sometimes a pounding heart. The NHS guidance on iron-deficiency anaemia explains that a simple blood test confirms it, and that iron tablets, taken for around six months, restore your levels and your energy. On the food side, iron-rich choices such as lean red meat, lentils, beans, tofu and leafy greens top up your stores, and a squeeze of vitamin C, think oranges, peppers or tomatoes alongside, helps your body absorb more. So if heavy periods and exhaustion go hand in hand for you, mention both to your GP, because treating the iron is part of feeling like yourself again.
What can help?
The reassuring headline is choice. The NHS describes a range of treatments for heavy periods, and your GP will help you find the fit for your body and your plans, including whether you hope to have a baby soon. Options include:
- The hormonal coil (IUS), often suggested as a first option, which thins the womb lining and tends to lighten bleeding over a few months.
- Tranexamic acid tablets, taken during your period to reduce blood loss, a hormone-free choice many women appreciate.
- Anti-inflammatory tablets such as mefenamic acid, which can ease both bleeding and cramps.
- The combined pill or other hormonal options, which can make periods lighter and more predictable.
- Iron support where blood tests show you need it, to rebuild your energy.
It also helps to know what a GP visit often involves, so it feels approachable. Your GP will usually ask about your cycle and your symptoms, may arrange a blood test to check your iron, and sometimes suggests an ultrasound scan to look at your womb and ovaries. They will talk through whether you hope to have a baby soon, since that shapes which options suit you best, and where symptoms point to a specific cause such as fibroids, they may refer you to a specialist for further options.
Alongside any medical route, small comforts ease the heavy days: a heat pad softens cramps, gentle movement like a slow walk lifts your mood, and keeping iron-rich foods on your plate supports your energy through the bleed. Rest is productive here, so give yourself permission to take the lighter day your body asks for.
Try this tonight: Start a simple period log on your phone. For one cycle, note how often you change protection, any flooding or clots, your energy each day, and how it shapes your plans. Add one iron-friendly meal this week, such as lentils, spinach or lean red meat with a squeeze of vitamin C to boost absorption. You walk into your GP appointment with clear evidence, and evidence is what gets you taken seriously.
When to book a GP appointment
Make the call whenever heavy periods affect your work, sleep, relationships or peace of mind. Book promptly if you soak through a pad or tampon every hour for several hours, pass very large clots, bleed between periods or after sex, or feel persistently exhausted and breathless. These are common, treatable situations, and seeking help early often makes the path shorter and gentler. Asking for support is a wise, self-respecting step.
The gentle takeaway
Heavy periods are common, and living around them month after month asks a quiet, steady toll. The hopeful truth is that menorrhagia is well understood and very treatable, and that sorting the iron side often lifts your energy as much as easing the bleeding lifts your days. Track a cycle, book the appointment, name the impact plainly, and expect real options. You deserve periods that fit your life, and the support to get there.
