Two studies recently published show that acupuncture can be an option for treating hot flashes. Hot flashes are a common problem for menopausal women and as any woman who has suffered from them can tell you they can be very uncomfortable and have a significant impact on quality of life, particularly with sleep. I have seen great results treating hot flashes/night sweats in my patients. Results can be dramatic, some patients were having several a day before their first acupuncture treatment and had none or only an occasional occurrence after their first treatment. In some cases this was even with patients who had previously undergone hormone replacement therapy to treat their menopausal symptoms with no relief.
