The pathophysiology of menopausal symptoms

Hormone Replacement Therapy (HRT) is widely used in the management of symptoms associated with oestrogen withdrawal such as hot flushes, night sweats, sleep disturbance, vaginal dryness and dyspareunia, but has no proven role in the treatment of midlife depression or arthritis. HRT prevents menopausal bone loss and osteoporotic fracture, though long-term use remains controversial because of the increased risk of breast cancer, myocardial infarction and stroke, as reported by the Women's Health Initiative. An understanding of the pathophysiology of menopausal symptoms and the risks and benefits of both hormonal and non-hormonal treatments assists in the individual management of patients.
