Body Odor Changes
A sudden, pungent change in how your sweat smells, often resembling a metallic or 'onion-y' scent.
Biological Mechanism
Estrogen drop shifts the bacterial microbiome of the skin. Additionally, an increase in sympathetic nervous system activity (hot flashes) causes apocrine glands to secrete a thicker, lipid-rich sweat that skin bacteria feast upon, creating a newly pungent odor.
Common Misdiagnoses
Poor hygiene, Dietary changes
Evidence-Based Treatments
- 01Clinical strength antiperspirant
Blocks the apocrine secretion.
- 02HRT
Controls the vasomotor sweeping, reducing the volume of apocrine release.
