Key Finding
Acupuncture plus self-care reduced hot flash frequency by 2.1 episodes per day more than self-care alone in postmenopausal women over 12 weeks (P<0.001).
Hot flashes are one of the most common and bothersome symptoms women experience during menopause, affecting sleep, mood, and daily activities. The ACUFLASH study examined whether acupuncture could help reduce these symptoms in postmenopausal women. This multicenter randomized controlled trial included 267 postmenopausal women who were experiencing at least seven hot flashes per day. Participants were divided into two groups: one received 10 acupuncture sessions plus self-care advice, while the control group received only self-care advice. Women in both groups tracked their hot flashes in a diary over 12 weeks, recording how often they occurred and how severe they were on a scale of 0 to 10. The results showed that acupuncture made a meaningful difference. Women receiving acupuncture experienced a reduction of nearly 6 hot flashes per day, compared to about 4 fewer hot flashes in the control group—a statistically significant difference of approximately 2 hot flashes per day. The intensity of hot flashes also decreased more in the acupuncture group. Beyond just hot flash reduction, women receiving acupuncture reported improved quality of life, including better sleep and fewer physical symptoms related to menopause. These improvements were measured using a standardized questionnaire designed specifically for women's health. The study suggests that acupuncture, when combined with self-care strategies, can provide clinically meaningful relief from menopausal hot flashes and improve overall well-being during this transition. If you're considering acupuncture for menopausal symptoms, seek treatment from a licensed acupuncturist trained in women's health.
The ACUFLASH study was a multicenter pragmatic randomized controlled trial evaluating individualized acupuncture plus self-care versus self-care alone for menopausal hot flashes. The study enrolled 267 postmenopausal women experiencing ≥7 hot flashes per 24 hours. The intervention group (n=134) received 10 acupuncture sessions, while controls (n=133) received self-care advice only. At 12 weeks, hot flash frequency decreased by 5.8 per 24 hours in the acupuncture group versus 3.7 in controls (difference of 2.1, P<0.001). Hot flash intensity decreased by 3.2 units versus 1.8 units respectively (difference of 1.4, P<0.001). The acupuncture group showed statistically significant improvements in vasomotor, sleep, and somatic symptom dimensions on the Women's Health Questionnaire. Urinary calcitonin gene-related peptide remained unchanged, suggesting mechanisms other than CGRP modulation. Clinical takeaway: Ten sessions of individualized acupuncture provides clinically relevant reduction in hot flash frequency and intensity with improved quality of life outcomes in postmenopausal women.
