Atrophic Vaginitis

Key facts

• Atrophic vaginitis is thinning, dryness, and irritation of the vaginal lining caused by falling oestrogen levels, most commonly after menopause.
• Symptoms include dryness, burning, itching, and pain during sex; urinary urgency or repeated infections sometimes come with the vaginal changes.
• First-line treatment is local oestrogen, usually estriol, applied directly to the vaginal tissue rather than taken as a systemic hormone.
• Unusual bleeding or discharge alongside these symptoms needs a doctor's assessment to rule out other causes.

What atrophic vaginitis is

Declining oestrogen makes the vaginal lining thinner, drier, and less elastic than it was before. It is most common after menopause, when oestrogen production falls permanently, but it can also happen during breastfeeding or after certain cancer treatments that lower oestrogen levels temporarily. The thinner tissue is easily irritated by friction, clothing, or sex, and symptoms tend to build gradually rather than appear overnight.

Why oestrogen matters for vaginal health

Oestrogen keeps vaginal tissue supple, moist, and resistant to minor injury. It also helps maintain the vagina's normal acidity, which keeps harmful bacteria in check. When oestrogen falls, both the tissue and its protective chemistry change at once, which is why dryness and minor infections often arrive together rather than as separate problems.

How it's treated

Local oestrogen therapy is the standard treatment. Estriol is applied directly to the vaginal tissue as a cream, pessary, or ring, restoring moisture and tissue thickness with only a small amount absorbed into the bloodstream. Because so little reaches general circulation, it carries a different, generally more favourable safety profile than oestrogen taken by mouth. Regular use over several weeks typically brings noticeable improvement, and treatment is often continued long-term since symptoms tend to return once it stops. Non-hormonal vaginal moisturisers and lubricants can ease symptoms too, particularly for milder cases or alongside oestrogen. This condition sits within the broader women's health category.

When to see a doctor

See a doctor if dryness and irritation persist despite treatment, or promptly if you notice unusual vaginal bleeding, unexplained discharge, or pain that doesn't fit the usual pattern, since these need assessment to rule out other causes.
