Vaginal Dryness
Vaginal dryness is most common with menopause, breastfeeding, or certain medications. Moisturizers and lubricants are first-line; a few supplements have limited supporting evidence as adjuncts.
TL;DR
Most often related to menopause, breastfeeding or medications that lower oestrogen. Moisturisers and lubricants are first-line, with vaginal oestrogen highly effective; supplement evidence is limited.
Overview
Vaginal dryness reflects thinning and reduced lubrication of the vaginal tissue, usually driven by falling oestrogen - at menopause, during breastfeeding, after certain cancer treatments, or with medications such as aromatase inhibitors, some contraceptives and antihistamines. It is part of what is now called genitourinary syndrome of menopause, which also includes irritation, painful sex and urinary symptoms, and unlike hot flushes it tends to persist and progress rather than resolve with time. Non-hormonal management works well for many: vaginal moisturisers used regularly two to three times weekly to maintain tissue hydration, and separate lubricants for intercourse, with water or silicone-based products preferred and pH-balanced formulations better tolerated. Regular sexual activity or use of dilators helps maintain tissue elasticity. Low-dose vaginal oestrogen is highly effective, acts locally with minimal systemic absorption, and is appropriate for most women including many with a history of breast cancer after specialist discussion. Supplement evidence is limited and mostly indirect: vitamin E and hyaluronic acid used vaginally have small trials showing symptom improvement, sea buckthorn oil taken orally has one modest trial, and oral phytoestrogens have inconsistent results for vaginal symptoms specifically.
How It's Diagnosed
When to See a Doctor
See a clinician for bleeding after sex or after menopause, persistent pain despite lubricants, unusual discharge or odour, or dryness with sores, which need direct assessment.
Supplements Studied For This
Hyaluronic Acid
Vaginal hyaluronic acid acts as a moisturiser and modestly eases dryness; oral supplements are untested for it.
Vitamin E
Promising but thin: small 8-12 week trials of vaginal vitamin E are mostly positive, and there is no evidence for oral vitamin E.
DHEA
Vaginal prasterone modestly eases menopausal dryness; oral DHEA supplements are not shown to help.
