Postmenopausal describes a woman after the menopause: her monthly bleeding has stopped, and that change is behind her, not still happening. Doctors use it when they talk about bones, heart health, or hormones in the years after that change. It is a calm medical word, not a joke about age, and not a rude label. Though actually, everyday English often just says “after the menopause,” which is easier to hear. Menopausal is the word for the time of the change itself; postmenopausal is later. People sometimes mix those two. You will see it in health articles and clinic notes much more than in friendly talk.
