What is the difference between vaginal atrophy and lichen sclerosus?
Vaginal atrophy and lichen sclerosus are different conditions. Vaginal atrophy is caused by oestrogen deficiency and affects the internal vaginal walls, while lichen sclerosus is a chronic skin disorder mainly affecting the external vulva and is unrelated to hormone levels.
Detailed Medical Explanation
Vaginal atrophy presents as internal dryness, thinning, and discomfort due to low oestrogen after menopause. Lichen sclerosus appears as white, patchy, thin, itchy, or painful skin on the vulva (external genitalia) and is an autoimmune skin disorder. Management and treatment differ for each. NHS: Vaginal Atrophy | NHS: Lichen Sclerosus.
Clinical Context
Lichen sclerosus often needs specialist diagnosis and steroid treatment. Vaginal atrophy is managed with moisturisers, lubricants, and oestrogen therapy.
Evidence-Based Approaches
Clear diagnosis is important because both may cause vulval/vaginal discomfort but need different therapies. RCOG: Vulval Disorders.
