Understanding and Managing Hot Flashes (Vasomotor Symptoms)
Hot flashes, clinically known as vasomotor symptoms (VMS), are a common experience during menopause, substantially impacting quality of life for many women. This document outlines the symptoms, causes, diagnosis, treatment, and prevention strategies associated with these frequently enough disruptive episodes.
Symptoms
The hallmark of a hot flash is a sudden feeling of intense warmth, typically spreading across the face, neck, and chest. This sensation can be accompanied by sweating, flushing (reddening of the skin), and a rapid heartbeat. Hot flashes can range in severity from mild warmth to debilitating heat that interferes with daily activities. They can occur during the day or night (night sweats). The frequency and intensity of hot flashes vary greatly among individuals.
Causes
Hot flashes are primarily linked to hormonal changes occurring during menopause, specifically the decline in estrogen levels. This decline disrupts the hypothalamus, the brain region responsible for regulating body temperature. This disruption leads to the brain mistakenly perceiving a slight increase in body temperature, triggering a cascade of events – including blood vessel dilation and sweating – to cool the body down, resulting in the sensation of a hot flash. Beyond hormonal shifts, factors like genetics, lifestyle, and certain medical conditions can also influence VMS. The brain’s chemical signaling plays a role, as targeted by some newer treatments.
Diagnosis
Diagnosis of hot flashes is typically based on a woman’s self-reported symptoms and medical history. There is no specific medical test to diagnose hot flashes. A healthcare provider will likely discuss the frequency, severity, and impact of the symptoms on daily life. They will also rule out other potential medical conditions that could be causing similar symptoms, such as thyroid problems or infections. Tracking hot flash occurrences – noting time of day, triggers, and severity - can be helpful for both the individual and their healthcare provider.
Treatment
Several treatment options are available to manage hot flashes, ranging from hormonal therapies to non-hormonal medications and complementary approaches.
* Hormone Therapy (HT): Historically, HT was a primary treatment, but its use has become more nuanced due to potential risks. It remains highly effective in reducing the frequency and severity of VMS.
* Non-Hormonal Medications:
* Fezolinetant (Veozah): Approved by the FDA in 2023, this medication works by blocking neurokinin 3 receptors, impacting brain chemical signaling. studies demonstrate a rapid and ample reduction in VMS frequency and severity, alongside improvements in health-related quality of life. However, the FDA issued a warning on September 12, 2024, regarding a rare but serious risk of liver injury. Women experiencing new-onset fatigue, jaundice, nausea, or vomiting should discontinue use.
* Elinzanetant (Lynkuet): Approved by the FDA in October 2025, elinzanetant is a neurokinin 1 and neurokinin 3 receptor antagonist, also managing brain chemical signaling to prevent hot flashes. It is reported to have minimal side effects.
* Complementary and Choice Remedies: While many natural products, herbs, and dietary supplements are marketed for hot flash relief, the evidence supporting their effectiveness is mixed, and long-term safety is often unknown. More research is needed. Psychological treatments, dietary changes, and exercise are generally considered safer options. A study in Menopause found that acupuncture, yoga, and health and wellness education classes were effective in reducing hot flash frequency compared to controls.
* Other Potential options: Stellate ganglion blockade, an injection into nerves in the neck, is sometimes used for pain management and can also decrease hot flashes. Dietary modifications, such as a low-fat, vegan diet with at least ½ cup of soy beans daily, may help, but further research is required to confirm efficacy.
Prevention & Management During a Hot Flash
While complete prevention isn’t always possible, several strategies can help minimize hot flash occurrences and manage symptoms when they arise:
* Lifestyle Modifications: Lifestyle changes can help prevent hot flashes and address other menopause symptoms like sleep disturbances or mood swings.
* Layered Clothing: Wearing layers allows for easy adjustment to changing body temperatures.
* Cooling Techniques: running cold water on wrists or using a hand-held fan can provide immediate relief.
* Environmental Control: Maintaining a cool surroundings and avoiding triggers like spicy foods, caffeine, and alcohol can help.
* Dietary Considerations: While diet alone cannot stop hot flashes, certain food choices may offer some benefit.
