When women experience reduced menstrual flow and dysmenorrhea, it is important to ask in detail about their menstrual history, including whether they have had any intrauterine procedures. For instance, some women may experience reduced menstrual flow and dysmenorrhea after undergoing late-term abortions, multiple childbirths, diagnostic curettage, or abortion surgeries. At this time, it is essential to consider whether there are any uterine factors, such as intrauterine adhesions that could cause these symptoms. Besides affecting menstruation, these conditions can also lead to infertility in women. A hysteroscopic examination can be performed for diagnosis. Additionally, some women might exhibit these symptoms without any abnormal medical history; in such cases, the causes could be endocrine disorders or primary dysmenorrhea.
