Heavy periods: we hate them. 1 in 5 women suffer from heavy bleeding, but their symptoms may often be dismissed and ignored, for upwards of 8-10 years (endometriosis sufferers can relate!). There’s even a hashtag (#WeHateHeavyPeriods) and robust awareness campaign underway, fronted by Actress, Comedian, Director and Women’s Health Activist Aisha Tyler ( We had the pleasure of sitting down with Aisha, Dr Cindy Basinski and Jenelle Shaw at a recent women’s health and empowerment event, where Ms. Tyler reminded us of ‘how important it is to be engaged in our own medical care.’


By talking about heavy periods, we can remove the stigma and taboos that continue to enshroud the disorder. But how do we know what’s normal, and when it’s time to seek help?

Abnormal uterine bleeding (AUB) refers to any change in the regularity, frequency, heaviness or length of menstruation (Brennan et al. 2018), with heavy menstrual bleeding (HMB) among the most common clinical presentations of AUB (Elmaoğullari et al. 2018). This common gynecologic problem occurs in approximately 10-35% of women (Kaunitz 2017), including adolescents (Elmaoğullari et al. 2018). But how much is too much, and for how long? Average blood loss during menses has been defined as approximately 30-40 milliliters (2-3 tablespoons) over a period of 4-5 days; a loss of more than 80 milliliters (twice the normal amount) in one cycle - which may last upwards of 7 or more days - is considered heavy and prolonged menstrual bleeding (Smith 2017).

However, thought leaders have pointed out various shortcomings to this volume definition, as actual blood loss is largely subjective and difficult to quantify objectively (Apgar et al. 2007). Instead, physicians will often rely on the patient narrative: how heavy periods affect her physical, social and emotional status. The need to change menstrual hygiene products after only one or two hours, feeling fatigued or weak during menses and passing sizable clots are among common physical indicators (NCBI 2017). Severe cramping, clotting, nausea and exhaustion are not unusual. Anemia is also common, though it is not required for a diagnosis of AUB.

According to Hologic, women with AUB miss an average of 18 days a year from work and/or school. In addition, 81% find that their heavy period is disruptive to their sex life; 73% say their relationships with others are negatively impacted; and more than 60% have had to miss social or athletic events as a result of heavy bleeding. But it’s not just “a woman’s problem:” the estimated annual direct costs associated with heavy menstrual bleeding is a staggering 1 billion dollars, with indirect costs soaring past 12 billion dollars due to the impact on lost work and quality of life (Sriprasert et al. 2017). It's time to end the silence!

There are various potential causes for AUB, ranging from primary endometrial dysfunction, von Willebrand disease, fibroids, hypothyroidism, hyperprolactinemia, polycystic ovary syndrome and polyps, to adhesions, clotting disorders, adenomyosis or endometriosis  (Brennan et al. 2017, Elmaoğullari et al. 2018, NCBI 2017). Rarely, malignancy may be at the root of the heavy bleeding; sometimes, no clear cause can be defined. Blood tests, pelvic examination, Pap, biopsy, ultrasound or hysteroscopy may be ordered to help clarify the diagnosis, depending on the patient’s specific situation. Treatments may involve medical and/or surgical interventions, and will depend largely on the individual’s fertility plans and the underlying cause of her heavy bleeding. The American College of Obstetricians & Gynecologists states that “treatment for acute AUB should be chosen on the basis of clinical stability, overall acuity, suspected etiology, desire for future fertility and underlying medical problems” (ACOG 2015). To that end, a levonorgestrel-releasing intrauterine device, combined oral contraceptives, progestins or non-steroidal anti-inflammatory drugs (NSAIDs) may be among options offered as medical therapies. In patients with adenomyosis, endometriosis, fibroids or other gynepathology, Laparoscopic surgery may be indicated. Each situation will be handled on a case-dependent basis between the patient and her healthcare partner.

Hysterectomy offers a definitive surgical approach to abnormal uterine bleeding; however, many individuals may seek alternatives to removal of their uterus. One such option is the Novasure® endometrial ablation. This quick, in-office procedure has been demonstrated to be “one of the most effective second-generation techniques in the treatment of chronic heavy menstrual bleeding” (Al-Inizi S 2017). The procedure removes the layer of the uterus, called endometrium, which causes heavy bleeding. It is critical to note that although the uterus remains intact, future fertility is contraindicated. The procedure is not for everyone, and is not without risks, so be sure to check with your personal physician to determine if endometrial ablation is right for you (note: endometrial ablation is not the same procedure as Laparoscopic ablation of endometriosis lesions).

If you suffer from heavy bleeding and your period is affecting your quality of life, physical health, or social and emotional well-being, talk to your doctor. You are not alone, and there are options – and you don’t have to suffer in silence. As Ms. Tyler says, "'it’s time for real talk about below the belt health.”
