As people enter menopause, I really often hear in the consultation room, "Suddenly my face and neck flush hot and sweat breaks out." In medicine, such facial flushing and sweating are called vasomotor symptoms, one of the most common changes appearing in women around menopause. Many people endure it, thinking "if I bear with it, it will pass," but once you know the cause, the methods that help are more varied than expected, from lifestyle adjustment to non-hormonal drugs to hormone therapy. Today I will organize at once why menopausal facial flushing occurs and what options there are.
Why does facial flushing occur?
The starting point of menopausal facial flushing is the change in which, as ovarian function declines, estrogen decreases. Estrogen acts on the hypothalamus, our body's temperature-regulation center, to keep the allowable range of "up to about this temperature is fine" broad.
When estrogen decreases, this allowable range narrows, so the body reacts hypersensitively even to a small temperature change that would normally be nothing. As a result, blood vessels suddenly dilate and sweat appears, producing the symptom of the face flushing hot.
In recent research, it has been revealed that the KNDy neurons of the hypothalamus and a substance called neurokinin B serve as the key switch of this process, and new treatments targeting this have also emerged. That is, facial flushing is not because willpower is weak or one is oversensitive but a clear physiological phenomenon arising when hormonal change shakes the temperature-regulation circuit.
In the consultation room, the intensity of symptoms is not necessarily proportional to blood test values. There are people whose hormone levels are at the borderline yet whose symptoms are frequent enough to make daily life hard, and there are the opposite cases too. So we start the consultation based on "how uncomfortable it actually is" rather than the numbers.
What symptoms can come together?
Vasomotor symptoms more often appear together with other menopausal changes than alone. The secondary discomfort caused by them, rather than facial flushing itself, sometimes lowers quality of life more.
In particular, facial flushing and cold sweats appearing at night, the so-called night sweats, frequently interrupt sleep. When you cannot sleep well, a vicious cycle arises that leads to daytime fatigue, reduced concentration, and emotional ups and downs.
- The face, neck, and chest suddenly flush hot and turn red
- Sweat gushes out and chills follow
- Night sweats that wake you from sleep with cold sweat
- Lowered sleep quality and the resulting daytime fatigue
- Accompanying symptoms such as palpitations, anxiety, and irritability
If such symptoms overlap, it helps to understand together the overall causes and mechanisms of menopausal body change rather than looking only at facial flushing. If sleep problems are prominent, we recommend also examining the relationship between menopause and insomnia.
Lifestyle habits to check first
Before pondering treatment, the order is to first check the parts you can adjust in daily life. Lifestyle adjustment alone does not make all symptoms disappear, but when combined with other treatments it reduces the overall burden.
Common factors that trigger or worsen facial flushing include hot and spicy food, caffeine, drinking, smoking, and a hot environment. If you record your own triggers for a few days, a pattern often becomes visible.
However, there is a point to note. The North American Menopause Society's (NAMS) 2023 nonhormone treatment recommendation organized that methods such as avoiding triggers or cooling therapy are safe and worth trying, but the evidence that they themselves reduce facial flushing is not yet sufficient. That is, it is good to know in advance that you should take care of lifestyle adjustment as a basic, but this alone may not resolve it.
It is reported relatively consistently that, if overweight, weight loss can help relieve symptoms. A regular life and maintaining an appropriate weight are also beneficial for overall health management in menopause.
Non-hormonal drug treatment
When there is resistance to hormone therapy or hormone use is medically difficult, non-hormonal drugs become a realistic alternative. In the consultation room too, quite a few people first look for other methods, saying "hormones are a bit burdensome."
The non-hormonal options that NAMS's 2023 recommendation organized as having evidence are as follows.
| Category | Example | Note |
|---|---|---|
| Antidepressant-class drugs | Some SSRI and SNRI classes | A decrease in facial flushing frequency is reported |
| Neuropathic-pain-class drug | Gabapentin | May help with nighttime symptoms |
| Cognitive behavioral therapy and clinical hypnosis | Non-drug approach | Help with symptom coping and sleep is reported |
| New non-hormonal agent | Neurokinin receptor blocker | A class newly introduced abroad |
In particular, as a drug directly targeting the neurokinin B pathway explained earlier was approved abroad in 2023, the range of non-hormonal treatment has widened. However, since these drugs each have different indications and precautions, whether to prescribe must be decided considering your underlying conditions and the drugs you are taking. It is safe to judge through consultation which non-hormonal drug suits you.

When is hormone therapy considered?
The treatment known to be most effective for moderate or greater vasomotor symptoms is hormone therapy. NAMS's 2022 hormone therapy recommendation also presents hormone therapy as the most effective treatment for vasomotor symptoms including facial flushing.
However, hormone therapy is not a treatment uniformly recommended to everyone. Because the benefit and harm differ according to the age at starting, the time elapsed since menopause, accompanying conditions, and the route of administration, it must be weighed individually.
Generally, in healthy women who start relatively early after menopause, that is, under 60 and within 10 years of menopause, it is reported that the benefit often exceeds the risk. Conversely, when there is a certain medical history, we approach cautiously or consider a non-hormonal alternative first.
The important thing is the process of synthesizing hormone levels, symptoms, and history to set the method, dose, and duration that fit you, and rechecking periodically. Referring together to the explanations of when hormone therapy is needed and menopausal hormone therapy helps in making a decision.
How should placenta injections be viewed?
Regarding menopausal facial flushing, I also sometimes receive inquiries about placenta injections. Among placenta-extract injections, some products have received domestic approval for improving menopausal symptoms, so they are mentioned as one option.
However, to speak honestly, large-scale, consistent evidence on how effective placenta injections are for facial flushing is still limited compared with hormone therapy or the non-hormonal drugs introduced earlier. Therefore, rather than expecting placenta injections as an all-purpose solution, we recommend judging after sufficiently discussing with medical staff what position it occupies as an auxiliary option in your situation. A more detailed explanation of placenta injections themselves is addressed in a separate article.
Signals that prompt a recommendation for care
If facial flushing is temporary and mild, you can prioritize lifestyle adjustment. However, in the following cases, evaluation through care is needed rather than self-judgment.
- When facial flushing continuously disrupts sleep and daily life
- When another hormonal problem such as thyroid disease is suspected
- When abnormal vaginal bleeding after menopause accompanies it
- When palpitations, anxiety, and depressed mood worsen together
In particular, menopausal symptoms sometimes need differentiation from other hormonal abnormalities including thyroid disease, so it is safe to first confirm the cause through testing. If you check the hormone state and accompanying conditions together with menopause screening, it is much easier to set the treatment direction. In clinical experience, treatment started after clarifying the cause also had higher satisfaction.
