How this protocol works
In plain language
Hot flashes (vasomotor symptoms) are sudden feelings of warmth, usually most intense over the face, neck, and chest. They're caused by changes in the body's thermoregulatory system during menopause, related to declining estrogen levels.
CHARACTERISTICS:
- Sudden sensation of heat spreading over body
- Flushing of face and upper body
- Sweating (especially at night - "night sweats")
- Rapid heartbeat
- Chills as the flash ends
- Duration: typically 1-5 minutes
WHO EXPERIENCES THEM:
- ~75% of menopausal women
- Can begin in perimenopause
- Duration varies: average 7 years, can persist 10+ years
- More severe in surgical menopause
- Also occur with cancer treatments, some medications
TRIGGERS:
- Hot drinks and spicy foods
- Alcohol
- Caffeine
- Stress
- Warm environments
- Tight clothing
TREATMENT OPTIONS:
- Hormone therapy: Most effective but not for everyone
- Non-hormonal medications: SSRIs/SNRIs, gabapentin, clonidine, oxybutynin
- Fezolinetant: New NK3 receptor antagonist
- Lifestyle: Dress in layers, keep cool, avoid triggers
Black cohosh* is the most studied herbal option.
Soy isoflavones* provide mild estrogen-like effects.
Evening primrose oil and vitamin E* are traditional remedies with modest evidence.
Expected timeline: Supplements may take 4-12 weeks to show benefit. Hot flashes often naturally diminish over time.
