Abstract
This proceeding summarizes a symposium on multidisciplinary menopause management held on April 13, 2024, as part of the American Academy of Medical Acupuncture’s 2024 conference. The workshop featured a presentation that integrated conventional medical perspectives and acupuncture therapy approaches to managing menopause symptoms. Topics included the stages of the menopausal transition, vasomotor symptoms, genitourinary syndrome of menopause, bone and cardiovascular health, and psychological well-being. The presentation also provided traditional Chinese medicine theories, pattern recognition in patient presentation, and evidence from clinical trials on acupuncture efficacy. In this study, we highlight the major points of the presentation.
INTRODUCTION
In April 2024, the American Academy of Medical Acupuncture (AAMA) annual symposium was held at the Radisson Blu Hotel Mall of America in Minneapolis, MN, with the theme “Embracing the Diversity of Acupuncture: Connecting People and Paradigms.” Several invited talks were presented, including the talk reviewed here: Menopause: There’s so much more to it than hot flashes and the Kidneys. The symposium included an overview of multidisciplinary approaches to managing menopause, including vasomotor symptoms and genitourinary syndrome of menopause, bone health (including osteoporosis, muscular strength, and mobility), and sexual and psychological health during menopause. In this report, we highlight the major points of the presentation.
BACKGROUND
It has been said that “menopause is having a moment.”1,2 From President Biden’s Executive Order 3 calling on Congress to make an investment of $12B in new funding for women’s health research and launching the White House Initiative of Women’s Health to many celebrities such as Oprah providing a Menopause Class 4 and Drew Barrymore talking about menopause, 5 we can see that menopause is active in public discourse. This activity is merited, as physicians6,7 and advanced practice providers 8 are undertrained in menopause medicine and many women who seek menopause care do not receive it. 9 It is a serious situation when neither providers nor patients have a clear picture of what this important life transition is, as well as what evidence-based conventional and integrative therapeutics are safe and indicated for symptom management and disease prevention. It is also important to note that women are seeking integrative health and medicine interventions: Roughly half of women seek integrative health care for vasomotor symptom management10,11 and acupuncture compared to usual care demonstrates moderate effect sizes in the treatment of vasomotor symptoms. 12 Thus, this talk was designed to provide an overview of the menopause transition stages and basics of conventional and scientific knowledge, followed by acupuncture therapy management of menopause symptoms.
PRESENTATION SUMMARIES
Conventional Care—Overview of Menopause
First off, it is important to note that the menopausal transition is a whole-person developmental transition. It is much more than solely the cessation of menses. Menopause is staged according to STRAW-10+ guidelines 13 and the basics of the guidelines are presented here. Perimenopause refers to the stage in the menopause transition characterized by irregular menstrual cycles (early perimenopause) or 2–12 months of no menstrual bleeding (late perimenopause). During perimenopause ovarian function is declining but still present, and estrogen, progesterone, and androgens (testosterone) levels are fluctuating. Perimenopause typically occurs in women's 40 s, but for some, it may occur as early as in their 30 s. Perimenopausal symptoms and irregular menstrual bleeding may last anywhere between 4 and 10 years. Testing estrogen levels during perimenopause is unlikely to be helpful because of how variable estrogens are during this time—estrogen is not declining linearly. Last, it is important to keep in mind that symptoms might not be related to perimenopause. Other possible causes of a woman’s symptoms in their 30 s or 40 s could be thyroid disorder, diagnosed anxiety/depression, diabetes/insulin resistance or metabolic syndrome, high cholesterol, high prolactin levels, and underlying sleep disorder, among other conditions. Postmenopause begins after amenorrhea of 12 consecutive months and lasts for the rest of a woman’s life. Early post menopause is characterized by bothersome symptoms for many and 10–16% of postmenopausal women experience vasomotor symptoms into their 70 s. 14
The menopausal transition may affect one or multiple systems of the body, ranging from pulmonary to digestive (see Table 1). Thus, it is important for clinicians to bear in mind that women may experience much more than hot flashes and night sweats. Other relevant and frequently reported symptoms include mood swings, lower sex drive, fatigue, anxiety, depression, lack of focus, poor concentration, incontinence, itchy or crawly skin, achy joints and muscles, headaches, digestive issues, allergies, weight gain, facial hair growth, changed body odor, burning of tongue/roof of the mouth, and more. 15 An identified symptom cluster of menopause includes vasomotor symptoms (VMS, hot flashes, night sweats, sense of anxiety, and/or palpitations), pain (onset or worsening), sleep problems, mood (anxiety and/or depression), and cognitive problems.16–18 With respect to VMS, duration varies by ethnicity, as reported by the Study of Women Across the Nation (SWAN): Japanese women experienced VMS an average of 4.8 years, White women 6.5 years, Hispanic women 8.9 years, and African American women 10.1 years. 19
All Systems May Be Affected
VMS are important to manage to increase comfort in women but also because VMS may have negative health consequences. These consequences are far-ranging, from cardiometabolic to bone and cognitive diseases. VMS are associated with increased risk of hypertension, insulin resistance, and worsening lipid profiles.20–22 A combined history of migraine and persistent VMS is associated with an increased risk for cardiovascular disease (CVD) and stroke, according to a recent analysis of women in the Coronary Artery Risk Development in Young Adults (CARDIA) study. 23 This is the first study to examine the joint influences of migraine and hot flashes/night sweats (vasomotor symptoms) independent of traditional heart disease risk factors and estrogen use. In fact, VMS may represent a novel female-specific CVD risk factor 24 as the American Heart Association indicates that menopause is a period of accelerated CVD risk. 25 VMS are also associated with decreased bone mineral density and increased risk of fractures.26,27 Recent studies also demonstrate associations between VMS and Alzheimer’s disease (AD). 28 VMS during sleep, known as night sweats, are associated with lower levels of beta-amyloid 42/20 which is a component of the known biology of AD. Low beta-amyloid 42/40 ratios are associated with a clinical diagnosis of AD, although this does not mean a patient definitely has the disease.
Acupuncture Therapy—Theory and Research Overview
Theory
Chinese medicine theory related to menopause dates back to the Inner Canon of the Yellow Emperor which has been a fundamental doctrinal source for Chinese medicine for more than 2,000 years. 29 This book comprises two texts—each of 81 chapters or treatises in a question-and-answer format between the mythical Yellow Emperor and six of his equally legendary ministers. The Suwen (素問), also known as Basic Questions, covers the theoretical foundation of Chinese medicine and its diagnostic methods while the Lingshu (靈樞; Spiritual Pivot), discusses acupuncture therapy in detail. Within the Basic Questions, women’s aging is described in 7-year cycles. For example, at age 14, Qi and Blood fill the meridians, and menses or Tian Gui (天癸, heavenly fluid) begin. Girls in the 1920s experienced puberty at an average age of 14, however, girls these days start puberty between 8 and 13 years of age. 30 At age 49 menstruation ceases. This age is close to the modern average of menopause in the United States, at 51 years. 15 Of clinical relevance to acupuncture therapy provision is that while menstruation has ceased, the Tian Gui is not completely absent. What remains of Tian Gui is directed toward the Heart. Blockage in the movement of Tian Gui to the Heart may result in palpitations, anxiety, or fatigue. 31 Thus, facilitating the smooth flow of Tian Gui is an important task for acupuncture therapy to reduce these common symptoms during the menopausal transition and early postmenopause. This age is also said to be marked by the decline of Spleen function & Kidney Jing (Essence). The decline of Spleen function—described as digestion more broadly—is essential to consider when treating midlife women. Without the middle Jiao properly digesting food that supports the manufacture of Qi and Blood, then not only will women experience digestive symptoms, but the center will not fulfill its role of balancing the upper and lower Jiaos. This may lead to the disruption of the Kidney and Heart being harmonized, a pattern commonly seen among midlife women.
Also, of importance to the provision of correct acupuncture therapy for menopausal symptoms is clarity regarding physiological Heat and pathological Heat in the body. There are two sources of physiological Heat in the body: Sovereign Fire, which is Heart Fire in the chest, and Ministerial Fire which is at the Ming Men, situated between the Kidneys. 32 Chaotic Ministerial Fire can flare up and irritate the chest, causing VMS. Acupuncture therapy would anchor or root the Ministerial Fire and reduce its flaring-up nature. Pathogenic Heat and Fire include external Heat that can invade the body and internal Heat can include pathogenic Heat harassing the Heart and Blood Heat. External Heat, in the form of Wind Heat, would be met with the Wei (Defensive) Qi, which governs the opening and closing of pores. People typically experience fever and chills, but fever (higher than normal core temperature) is physiologically distinct from vasomotor symptoms (increased sensitivity to external heat and cold, thus the temperature at which we chill or sweat changes, and thus a hot flash is due to the narrowing of this thermoregulatory zone). 33
Research
Quite a lot of research has been conducted on acupuncture therapy for VMS. In fact, a recent search in PubMed for acupuncture AND vasomotor delivers some 162 results, and this reduces to 82 records when adding menopause to the search, dating 1994–present. A brief overview of major randomized controlled trials (RCTs) includes three major trials:
2009 ACUFLASH
34
study randomized 267 postmenopausal women (Norway) to receive 10 weekly acupuncture treatment sessions + education (individualized) or education alone (control). The primary outcomes include greater hot flash frequency reduction (p < 0.001) and greater hot flash intensity reduction (p < 0.001) in the acupuncture group compared to the control. A secondary data analysis revealed that the most commonly used acupoints (regardless of syndrome diagnosed) were SP6 (Sanyinjiao), HT6 (Yinxi), KI6 (Zhaohai), KI7 (Fushou), CV4 (Guanyuan), LU7 (Lieque), LI4 (Hegu), LV3 (Taichong), ST36 (Zusanli), KI3 (Taixi).

2016 AIM
36
study (USA) randomized 209 peri- or postmenopausal women to receive 6 months of acupuncture (individualized) or waitlist control. Among those who received acupuncture, VMS decreased by 36.7% and increased by 6.0% in the control group (p < 0.001). At 12 months, the reduction from baseline in the acupuncture group was 29.4% when compared to controls (p < 0.001). 2019 ACOM
37
study (Denmark) 70 women with moderate/severe VMS were randomized to either acupuncture therapy for 5 weekly sessions or wait list control. Acupuncture protocol was associated with significantly reduced hot flushes (p < 0.001), and day and night sweats (p = 0.0056) compared to the wait list control group. The protocol consisted of CV3 (Zhongji), CV4 (Guanyuan), LR8 (Ququan), SP6 (Sanyinjiao), and SP9 (Yinlingquan).
The most recent meta-analysis of acupuncture for VMS included an umbrella systematic review which included three systematic reviews and four RCTs. 12 Acupuncture compared to usual care reduces VMS frequency with a moderate effect size (standardized mean differences [SMD] −0.66, 95% CI, −1.06 to −0.26, I2 = 61.7%, 5 trials) and VMS severity (SMD −0.49, 95% CI −0.85 to −0.13, I2 = 18.1%, 4 trials). Acupuncture compared to sham acupuncture SMDs were smaller or not statistically significant.
Acupuncture Therapy—Pattern Recognition Overview
One may apply general pattern recognition to peri and postmenopausal cases when determining the correct course of treatment. Given that the transition is a whole-person phenomenon, assessment of symptoms and signs is a particularly good fit with acupuncture therapy. That being said, here are several helpful tables to consider, according to the time of day or night that the VMS occurs. This is one way to organize one’s thinking, and of course, consider the whole clinical picture and adjust accordingly.
Morning VMS
One may consider deficiency in the center, with Spleen and Stomach being dysregulated (Table 2). Typically, women will present with digestive symptoms and associated pale complexion, weakness, and fatigue that is commonly seen with Spleen Qi deficiency. The Spleen/Stomach times are 7–11 am and thus correspond timing-wise for VMS. Of note is spontaneous sweating (sweating for no reason), common when the Spleen is deficient, and Qi is unable to hold the pores in check and thus sweat pours out. See Table 2 for acupoints to consider for acupuncture therapy.
Morning Vasomotor Symptoms
Afternoon VMS
When considering afternoon VMS, the most common presentations are Yang Ming excess or Blood Stasis (also an excess condition). The main differentiating factors are whether there are corresponding classical Yang Ming symptoms such as constipation, red tongue with a yellow, dry coat, and/or a deep, forceful pulse. Blood Stasis commonly presents with clotty, dark red menstrual fluid which may be accompanied by pain, a choppy pulse, mental restlessness and possibly high blood pressure, insomnia, and/or musculoskeletal pain. See Table 3 for acupoints to consider for acupuncture therapy.
Afternoon Vasomotor Symptoms
Evening and night VMS
Several key distinctions can be made between patterns of evening or night VMS. Overall, this is a time when Kidney and/or Heart may reveal dysregulation. Specifically, when Heart Yin and Blood are deficient, there is insufficient substance to hold and calm the Heart Shen (Spirit), manifesting as possible palpitations, insomnia, and 5-palm heat (hands, feet, center of the chest). When Kidney Yin is deficient, dry mouth, depression, anxiety, pale urine, dizziness, vertigo, poor hearing, achy bones, and/or poor memory may be seen. Lastly, when Kidney and Heart are disharmonized, both Kidney signs like achy back, dizziness, and tinnitus, as well as Heart signs (palpitations, poor memory) will be seen. This is a pattern of Tian Gui not flowing smoothly from the Kidneys to the Heart, and regulating this pathway between organs is essential for a patient to realize the full potential of the menopausal transition: nourishment of the Heart by Tian Gui. See Table 4 for acupoints to consider for acupuncture therapy.
Evening or Night Vasomotor Symptoms
CLOSING
The symposium ended with a robust question-and-answer session that highlighted the complexities and nuances of menopausal transition symptoms and management. In conclusion, the Menopause: There’s so much more to it than hot flashes and the Kidneys symposium provided an overview of what menopause and the menopausal transition are, associated symptoms, and disease risks, as well as insights into acupuncture therapy, approaches to the management of menopause symptom presentations. This workshop provided a platform to educate the audience on menopause-related topics affecting the health of women.
