Consult a healthcare provider if a girl is 14 years old and has not yet experienced the onset of secondary sexual characteristics (e.g., breast development and pubic hair), or if a girl is 16 years old and has not had her first menstrual period.
For women who have already started menstruating, they should seek medical attention if they have missed three consecutive menstrual periods.
Women with amenorrhea caused by ovarian insufficiency require annual follow-up. These follow-up appointments are conducted to monitor ovarian hormone replacement and identify the development of any associated conditions.
Girls can prevent primary amenorrhea resulting from excessive weight loss or weight gain by maintaining a healthy weight.
