Amenorrhea can be physiological or pathological. Physiological amenorrhea, for example, occurs during the breastfeeding period when menstruation is irregular for three consecutive months; this is considered normal. Also, some patients may experience temporary amenorrhea due to medications used to treat conditions such as endometriosis, which is also normal. Pathological amenorrhea, commonly seen in clinical settings, includes conditions such as ovarian dysfunction, severe intrauterine adhesions, premature ovarian failure, or other endocrine disorders, which can result in the absence of menstruation. It is essential for individuals experiencing amenorrhea to undergo relevant medical examinations to identify the cause, followed by appropriate treatments based on the findings.
