What Are Vasomotor Symptoms (VMS)?

Vasomotor symptoms—commonly known as hot flashes and night sweats—are among the most frequent and disruptive symptoms during the menopausal transition.


These symptoms are caused by changes in blood vessel dilation and constriction in the skin, leading to sudden heat release and flushing. The underlying trigger is hormonal fluctuation, which impacts the brain’s thermoregulatory center.


When Do These Symptoms Begin?

Hot flashes can start during perimenopause or even early postmenopause. They are reported by 30%–70% of premenopausal women, although symptoms in these earlier stages tend to be mild.


As women progress through perimenopause, VMS become more common and more intense, especially during the late transition phase—the time when menstrual cycles become irregular and amenorrhea (absence of menstruation) lasts 60 to 364 days.


Symptoms are typically most severe in the first 1–2 years after the final menstrual period (FMP). However, if hot flashes begin earlier in the transition, it may signal a longer duration of symptoms—in some cases lasting 10 years or more.


Risk Factors: Who’s More Likely to Experience VMS?

Several health and lifestyle factors influence when VMS begin and how intense they are:

  • Early-onset VMS: Higher BMI, older age at menopause, anxiety, and depressive symptoms

  • Late-onset VMS: Smoking and normal BMI

  • Persistent VMS: Higher BMI, greater alcohol use, and ongoing anxiety or depression


Quality of Life Impacts

VMS can affect more than just temperature control—they’re linked to:

  • Disrupted sleep and fatigue

  • Difficulty concentrating and mood instability

  • Lower overall quality of life

  • Increased risk factors for cardiovascular disease


Treatment Options

Hormone Therapy (HT)

  • Hormone therapy is often the most effective option for hot flashes. However, not all women are candidates for HT, and some prefer hormone-free approaches.


Naturopathic & Non-Hormonal Support

Supplements & Nutraceuticals

  • Phytoestrogenic herbs such as sage, black cohosh, & rhapontic rhubarb: May reduce hot flashes and night sweats by 4 weeks of use

  • Fish oil (DHA/EPA): Supports mood and brain function, but not hot flashes directly

  • Creatine: May enhance mood, cognitive function, and energy


Diet & Nutrition

  • Low-fat dairy: Supports a healthy weight and body composition

  • Phytoestrogens (plant-based estrogens such as soy): particularly if these foods replace some red meat intake

  • Blood sugar regulation: minimizing sugar and focusing on complex carbohydrates, vegetables, fruit, legumes, nuts and seeds.


Lifestyle & Mind-Body Strategies

  • Exercise: Studies have shown physically active women to have significantly fewer severe vasomotor

  • symptoms than sedentary women.

  • Clinical hypnosis: Demonstrated benefit in clinical trials

  • Modest weight loss: Reduces the impact of VMS in overweight individuals
