What is Heavy Menstrual Bleeding (HMB)?

It is likely that, from time to time, you will experience heavier than usual bleeding during your menstrual period, but it can be hard to know if this is normal or if your periods are heavy compared with other women. Heavy menstrual bleeding (HMB) can be a serious and debilitating condition.

It is defined by the impact it has on a woman's physical, social and emotional quality of life, for example if your monthly period limits your normal daily activities, or affects your role at work.

A good indication that blood loss is excessive is if you experience any of the following:

  • Are using an unusually high number of tampons or pads, for example if there is enough blood to soak a pad or tampon every hour for several consecutive hours

  • Are experiencing flooding (heavy bleeding) through to clothes

  • Need to use double protection, i.e. tampons and pads together

  • Are experiencing night time bleeding that requires you to get up to change pads or tampons, use extra protection at night and / or change your bed sheets

One in three women have heavy menstrual bleeding at some point in their lives.

83% of women with HMB state that it affects their daily activities:

91% feel HMB impacts their ability to perform sport and fitness activities

80% feel that their heaviest bleeding days affect their performance at work

68% do not tend to participate in social activities when their period is heavy

However, in up to 60% of women with HMB, no underlying cause is found. This means that many women can be treated by their GP.
