What are the reasons for reduced menstrual flow?

Patient's question:

What are the reasons for reduced menstrual flow?

Doctor's answer:

Hello: There are two major causes of menstrual disorders:
1. Neuroendocrine dysfunction: This primarily involves instability or defects in the hypothalamic-pituitary-ovarian axis, which is known as menstrual disorders.
2. Organic lesions or drug-induced causes: This includes local inflammation, tumors, and developmental abnormalities of the reproductive organs; malnutrition; intracranial disorders; other endocrine dysfunctions such as thyroid, adrenal cortex dysfunction, diabetes, Sheehan's disease, etc.; liver diseases; blood disorders, etc. The use of psychiatric medications, endocrine preparations, or the use of intrauterine devices (IUDs) for contraception may also lead to menstrual disorders. Certain occupations, such as long-distance runners, are prone to amenorrhea. Additionally, some abnormal bleeding during pregnancy is often misinterpreted as menstrual disorders.
It is recommended to seek a definitive diagnosis before treatment and avoid self-medication.
