Rash, dryness, itchiness and other changes in skin texture can be symptomatic of reduced estrogen production during menopause, according to Dr. Claudia Aguirre of the International Dermal Institute. Estrogen keeps the skin hydrated and smooth. Menopausal women experience rash and itchiness because their skin retains less moisture.
High estrogen levels during pregnancy result in healthy skin and hair, colloquially described as a pregnant glow. During menopause, the opposite happens, and lower estrogen levels cause wrinkles as well as dry skin and rash, states Dr. Aguirre. Other physical changes include the inability to become pregnant, hot flashes and potential for other symptoms, such as pain during intercourse and difficulty sleeping.
Itchy rashes caused by menopause are treatable with hormone replacement therapy, which combines estrogen and progestin to relieve many of the symptoms of menopause, but the Illinois Department of Public Health advises against its long-term use. HRT increases risk of heart disease, blood clots, stroke and breast cancer. Phytoestrogens, found naturally in certain foods such as legumes, may also help relieve symptoms of menopause.
