Amenorrhea is generally defined in medicine as a condition where menstruation stops for three consecutive months. There are physiological and pathological types of amenorrhea. Physiological amenorrhea, such as not menstruating during breastfeeding or pregnancy, is considered normal and does not require medication for treatment. Pathological amenorrhea usually occurs when someone who normally has regular periods suddenly stops menstruating for three months. In such cases, it is essential to visit a hospital for relevant examinations and then treat accordingly based on the results. Common issues include ovarian dysfunction, premature ovarian failure, and elevated prolactin levels, all of which can lead to amenorrhea. Treatment should be chosen based on the examination results.
