Introduction
Heavy periods are so common that many women assume they are just something to put up with. You might have grown up hearing that painful, heavy bleeding is "normal," or that you should simply "get on with it". But there is a real difference between a heavy period and bleeding that needs medical help.
Around one in four women will have heavy periods at some point in their lives. Yet many wait years before asking for help. Often, they are not sure if their bleeding is "bad enough" to see a doctor. The truth is, if your periods are affecting your daily life, that is reason enough to ask for support.
What counts as a heavy period?
Doctors sometimes define heavy periods as losing more than 80ml of blood each cycle. But nobody measures that at home. It is not a useful number for most of us.
A better way to think about it is this: if your periods are getting in the way of your life, they count as heavy. It is about how they affect you, not just how much you bleed.
Some signs that your periods might be too heavy:
- You are soaking through a pad or tampon every hour or two, for several hours in a row.
- You need to use a pad and a tampon together, or wear nighttime pads during the day.
- You are passing blood clots bigger than a 10p coin.
- Your periods last longer than seven days.
- You are bleeding through your clothes or onto your bedding.
- You are skipping work, exercise, or seeing friends because of your period.
- You feel very tired, breathless, or dizzy during or after your period.
If any of these sound like you, it is worth talking to your GP. You do not need to have all of these symptoms. Even one or two is enough to ask for help.
Why do some women have heavier periods?
In about half of cases, doctors cannot find a specific cause. Your body simply has a heavier flow. That might feel frustrating when you are looking for an answer. But not having a "reason" does not mean your heavy periods are not real, or that nothing can be done. There are still treatments that can help you feel more like yourself again.
In other cases, heavy periods can be a sign of something else going on in your body.
Fibroids are growths in or around the womb. They are not cancerous and are very common. Up to 80% of women will have them by the age of 50, though many will never know. When fibroids do cause problems, heavy bleeding is often one of them.
Adenomyosis happens when the tissue that normally lines the womb starts to grow into the muscle of the womb. It often causes heavy bleeding and painful periods. It is most common in women in their 40s or those who have had children, but it can happen earlier.
Polyps are small growths on the lining of the womb. They are almost always harmless, but they can cause heavy or irregular bleeding.
PCOS (Polycystic Ovary Syndrome) is a hormonal condition that can make your periods irregular. When a period does come, it may be heavier because the womb lining has had more time to build up.
Endometriosis is when tissue like the womb lining grows outside the womb, for example, in the ovaries. This misplaced tissue causes significant inflammation and internal irritation, which can lead to much heavier, longer, and more painful periods
Perimenopause is the time leading up to menopause. During this stage, your hormones change. Periods may become heavier, longer, or less predictable.
Bleeding disorders are often missed. One example is Von Willebrand disease, which affects how your blood clots. Around 7,000 women in the UK have this condition. Studies show that about 1 in 5 teenage girls who see a doctor for heavy periods have an undiagnosed bleeding disorder. If you have always had heavy periods, bruise easily, or bleed for a long time after cuts or dental work, tell your GP.
If any of these conditions sound worrying, try not to panic. Most can be treated. Your GP can help you work out what is going on.
How heavy periods can affect your mood
It is easy to focus on the physical side of heavy periods. But the emotional side can be just as hard.
There is the constant worry. Have I got enough pads? Will I leak in the meeting? Can I make it through the school run without needing to rush home? That background anxiety in your head every single day of your period. It is exhausting.
Over time, it can chip away at your confidence. You might start saying no to things. Avoiding the gym. Cancelling plans. Feeling on edge for a whole week every month. Some women say they feel like they are planning their life around their period, rather than just having one.
Then there is the tiredness. Heavy bleeding can lower your iron levels. Low iron does not just make you tired. It can affect your concentration, your patience, and your mood. Feeling tearful or snappy during your period is not always "just hormones." Sometimes it is your body running on empty.
Getting your bleeding under control is not just about the physical side. It can give you back the confidence to make plans. To stop worrying. To feel like yourself again. That matters just as much.
When should you see a GP?
You do not need to wait until things are unbearable. If heavy periods are affecting your life, that is enough. But there are some situations where you should definitely see your GP:
- Your periods have become much heavier than they used to be.
- You are bleeding between periods or after sex.
- Your periods have become irregular after years of being regular.
- You are flooding through protection or passing large clots often.
- You feel very tired, weak, or short of breath.
- You have had heavy periods since you were a teenager, but have never been checked.
If you have sudden, very heavy bleeding that you cannot control, or you feel faint, breathless or unwell, get help straight away. Do not wait for a normal appointment.
Making the most of your GP appointment
When you see your GP, it helps to think about what matters most to you. What do you want to get back? Maybe you want to exercise without worrying about leaks. Maybe you need to get through a work day without changing your pad every hour. Maybe you just want to stop feeling so drained.
Telling your GP what matters to you helps them find a treatment that fits your life, not just one that looks right on paper.
If you can, keep track of your periods for a month or two before your appointment. Write down when they start, how long they last, how heavy the bleeding is, and how it affects your energy and your plans. You do not need an app. A notebook is fine, or download the file below 👇🏼
Having this information makes it much easier for your GP to understand what you are dealing with.
Your GP might suggest a blood test to check your iron levels. They might do a physical exam or send you for a scan. Not everyone needs tests. If your GP does not think you need a scan, that does not mean they are not taking you seriously. It usually means they are confident they can help you without one.
What treatments are available?
Treatment depends on the cause, your symptoms, and what you want. There are more options than you might think.
Hormonal coil (Mirena): This is often the first thing doctors suggest because it works well for most women. It releases a small amount of hormone into the womb, which thins the lining and reduces bleeding. Many women find that their periods become much lighter or stop altogether.
Tablets: Tranexamic acid is a tablet you take during your period. It can cut blood loss by up to half. Painkillers like ibuprofen can help with cramps and may also reduce bleeding slightly.
Other hormone treatments: The pill, the patch, or hormone tablets taken at certain times of your cycle can all help, depending on your situation.
Surgery: For women with fibroids, polyps, or other causes, there are procedures that can help. These include removing fibroids, removing the womb lining, or removing the womb itself. These are usually only offered if other treatments have not worked.
It might take a bit of time to find what works best for you. But there are options, and you do not have to work this out on your own.
Practical ways to manage heavy periods day to day
While you are waiting for an appointment or waiting for treatment to kick in, there are things you can do to make life easier. These will not fix the problem, but they can help you cope.
Look after your iron levels. Heavy bleeding means you lose iron. Low iron makes you tired, foggy, and run down. Eat foods rich in iron, like red meat, dark leafy greens, lentils, beans, and fortified cereals. Eating these with foods high in vitamin C, like a glass of orange juice or some peppers, helps your body take in more of the iron. If you are feeling very tired, ask your pharmacist or GP about iron tablets.
Drink plenty of water. Losing blood means losing fluid. You might feel thirstier than usual during your period. Drinking enough water can help with tiredness and headaches.
Plan ahead. If you know your first few days are the heaviest, plan around them where you can. Keep spare underwear, pads, and wet wipes in your bag. Wear dark clothes. Try to schedule busy days for when your period is lighter. This is not about shrinking your life. It is about working with your body, not against it.
Find protection that works for you. Period products have come a long way. If pads and tampons are not enough, try period pants as a backup or on their own for lighter days. Menstrual cups or discs hold more than tampons and suit some women better. You can layer products, too, like a cup with period pants as a safety net. It might take some trial and error to find what works for your flow.
Manage pain as well as bleeding. Heavy periods often come with cramps. A hot water bottle on your tummy can help. Ibuprofen can ease pain and may reduce bleeding a little. Paracetamol is another option if you cannot take ibuprofen.
Rest when you need to. Feeling tired during a heavy period is real. Your body is working hard. If you need to slow down, let yourself. A nap, an early night, or just sitting down for ten minutes is not lazy. It is sensible.
Track your cycle. Write down when your period starts, how long it lasts, how heavy it is, and any symptoms. This helps you spot patterns and gives your GP useful information.
Talk about it. Heavy periods can feel lonely, especially if you are hiding leaks or cancelling plans. Talking to someone you trust can help. A friend, a family member, or even an online group. You might be surprised how many people have been through the same thing.
These tips will not solve the problem. But they can make things easier while you wait for answers or adjust to treatment. Be patient with yourself. Managing heavy periods is hard.
When to get urgent help
Most heavy periods are not emergencies. But some symptoms need quick attention:
Sudden, very heavy bleeding that you cannot control. Feeling faint, dizzy, or very unwell. Feeling extremely tired or short of breath even when resting. Chest pain.
If you have any of these, do not wait for a normal GP appointment. Call NHS 111 or go to A&E.
You do not have to just "get on with it"
Heavy periods have been brushed off for too long. You might have been told it is just part of being a woman. That you will grow out of it. That everyone has bad periods.
But that advice was wrong. Heavy bleeding is not something you should just put up with, especially when help is out there.
Every year, around 50,000 women in England and Wales are sent to hospital clinics for heavy periods. That is a lot of women. It tells you something important: you are not alone, and this is something doctors see and treat all the time.
If your periods are affecting your work, your friendships, your sleep, or your ability to leave the house, you have every right to ask for support. Talk to your GP. Keep a note of your symptoms. And if you feel like you are not being heard, ask for a second opinion or to be referred to a specialist.
Be kind to yourself. You deserve to feel confident and in control of your own body.
