Menopause, confirmed after at least 12 consecutive months without menses or when both ovaries are removed or permanently damaged, marks the end of fertility. Menopause is a natural biological process, not a medical illness. Even so, the physical and emotional symptoms of menopause can disrupt your sleep, sap your energy and, at least indirectly, trigger feelings of sadness and loss. Even though menopause is not a disease, you should not hesitate to seek treatment for severe symptoms. Many effective treatments are available, from lifestyle adjustments to hormone therapy.
