Women frequently ask what symptoms they can anticipate during menopause. In reality, each woman experiences menopause differently. Some women have changes in several areas of their lives. It is not always possible to tell if these changes are related to aging, menopause or both. While one woman is certain that insomnia is a menopause symptom for her, another feels joint aches are her primary menopause symptom. Doctors find it difficult to communicate to their patients about menopause and what could be a host of uncomfortable symptoms. For example, medical science cannot explain how declining hormone levels during menopause could cause joint pain. Menopause is not an illness, but a natural transition when a woman's reproductive ability ends. Yet many of the menopausal symptoms may mimic signs caused by diseases. When do women undergoing menopause need treatment in the first place? The same pattern of hot flashes in two women can have a very different psychological impact. For one woman, they can greatly disturb her daily functioning, while another may hardly be bothered.
