The management of the peri-or postmenopausal patient, whether symptomatic or asymptomatic, involves a careful assessment of the problems and expectations of each patient and the matching of appropriate treatment to their needs. The effects of the menopause and its treatment on the patient's immediate and long-term health must be taken into account. This may involve consideration of aspects of medical topics as diverse as gynaecological endocrinology, bone metabolism, oncology and cardiology. Although the benefits of oestrogen therapy are well established the response to therapy must be carefully monitored. Vigilance in the monitoring and seeking out of adverse effects both in individuals and populations must continue to ensure that any problems with this form of therapy are detected at the earliest possible stage.
