Bleeding- Heavy bleeding

15 Mar 2017.

NoteThis information is for cyclical hormone-related heavy bleeding only, if you may be pregnant, have just given birth, or had abdominal surgery, are menopausal, or do not have a menstrual cycle, please consult a doctor about any unusual bleeding.

Heavy menstrual bleeding– The medical term is ‘menorrhagia‘-  This is quite a common problem, which can significantly affect quality of life. Sufferers may feel unable to leave the house for fear of bleeding through their clothes, or lack of access to toilets; they may feel tired, dizzy, physically weak, or find it difficult to concentrate. Heavy menstrual bleeding can lead to iron deficiency anaemia.

Notes: Technically ‘heavy bleeding’ refers to losing over 80ml of blood during the course of a period. The easiest way to measure menstrual blood loss is by using a cup, especially one with clearly marked measurement levels e.g. the Mooncup. Otherwise, you can only estimate blood loss by counting how many tampons or pads you bleed through e.g. each soaked ‘super’ tampon or pad= approx. 10ml, each regular soaked tampon or pad = approx. 5ml. 

  • Do you have to wear tampons and towels together?
  • Do you have to change protection more than once every 2 hours?
  • Does blood ever soak through your clothes?
  • Do you have to stay off work or cancel social engagements due to bleeding?

If you have answered ‘yes’ to any of the above questions, you are probably suffering from heavy bleeding.


Conditions to rule out first, under medical supervision [1];

  • polycystic ovary syndrome (PCOS) – a common condition that causes irregular periods and when periods return they can be heavy
  • pelvic inflammatory disease (PID) – an infection in the upper genital tract (the womb, fallopian tubes or ovaries) that can cause bleeding after sex, or between periods
  • fibroids – non-cancerous growths that develop in or around the womb and can cause heavy or painful periods
  • adenomyosis – when tissue from the womb lining becomes embedded in the wall of the womb
  • endometriosis – when small pieces of the womb lining are found outside the womb, such as in the fallopian tubes, ovaries, bladder or vagina (although this is more likely to cause painful periods)
  • an underactive thyroid gland (hypothyroidism) – where the thyroid gland doesn’t produce enough hormones, causing tiredness, weight gain and feelings of depression
  • cervical or endometrial polyps – non-cancerous growths in the lining of the womb or cervix (neck of the womb)
  • blood clotting disorders, such as Von Willebrand disease
  • cancer of the womb (although this is relatively rare)

Medical treatments that can sometimes cause heavy periods include:


Managing menstrual cycle-related heavy bleeding (i.e. once alternative causes have been ruled out):

TOP TIP! Menstrual cups hold more blood than other sanitary products, they are also less likely to leak- especially a firm cup e.g. a Mooncup. If you would still prefer to have a ‘backup’ panty liner, we recommend washable cotton liners or period underwear– they are more economical (no tampon tax for a start!), better for the environment, more comfortable, and less sweaty than disposable products.

Try a hormone-balancing diet– As outlined in this blog, a vegetable-based ‘anti-inflammatory’ diet can significantly improve all hormone-related symptoms.We highlight a few of the key steps that are especially relevant for those suffering from heavy bleeding, below:

  • Avoid caffeine and alcohol– Although the clinical research is sparse, some studies have found that caffeine, and alcohol, consumption can cause heavier periods [2] [3]. Since a reduction in caffeine and alcohol is beneficial for many other hormone-related symptoms, it is probably worth avoiding them, to see if this reduces the heavy bleeding.
  • Try nutritional supplements– Interestingly, iron deficiency can be both a cause and result of heavy periods [4], so it is definitely worth taking an iron supplement (15-50mg daily) to see if this can reduce your menstrual bleeding [5]. You might also want to try taking a daily multivitamin, since studies have shown that vitamins A [6], and C [7], can significantly reduce heavy bleeding in some people.

If you have tried the suggested tips and tricks for at least 3 months, and your symptoms do not improve, please consult your doctor.
