What is Heavy Menstrual Bleeding (HMB) or Menorrhagia?¹

Heavy menstrual bleeding (HMB) is defined as excessive menstrual blood loss which interferes with a woman’s physical, social, emotional and/or material quality of life. It can occur alone or in combination with other symptoms.

HMB is one of the most common reasons for gynaecological consultations in both primary and secondary care. About 1 in 20 women aged between 30 and 49 years consult their GP each year because of heavy periods or menstrual problems, and menstrual disorders comprise 12% of all referrals to gynaecology services.

NICE recommends healthcare professionals recognise that heavy menstrual bleeding (HMB) has a major impact on a woman's quality of life, and ensure that any intervention aims to improve this rather than focusing on blood loss.

When agreeing treatment options for HMB with women, take into account:

  • the woman's preferences
  • any comorbidities
  • the presence or absence of fibroids (including size, number and location), polyps, endometrial pathology or adenomyosis
  • other symptoms such as pressure and pain.

Treatments for women with no identified pathology, fibroids less than 3 cm in diameter, or suspected or diagnosed adenomyosis:

 

    • LNG-IUS (Levonorgestrel-releasing intrauterine system)

 

    • Tranexamic Acid

 

    • NSAIDs (non-steroidal anti inflammatory drugs)

 

    • Combined hormonal contraception

 

    • Cyclical oral progestogens

 

    • Second-generation endometrial ablation

 

    • Hysterectomy

 

Please consult NICE guidelines for full treatment recommendations.
