Patient's question:
Detailed medical condition and purpose of consultation: Since September, my menstrual cycle has suddenly shortened to every 20 days. The amount of blood flow during each period has also decreased. Previously, it was around 28 days with heavy flow. I am 28 years old, have given birth, and have been using an IUD for nearly three years. I am active in sports and am wondering what could be causing this change.Duration and persistence of the current illness: 4 months
Current general condition: No discomfort is felt.
Medical history: None.
Previous diagnoses and treatment history and outcomes: None.
Ancillary tests: Normal results from ultrasound examination.
Doctor's answer:
1. Neuroendocrine dysfunction causes: Mainly the instability or defects in the function of the hypothalamic-pituitary-ovarian axis, which is known as menstrual disorders.2. Organic lesions or drugs may cause: Including local inflammation, tumors, and developmental abnormalities of the reproductive organs; malnutrition; intracranial diseases; other endocrine disorders such as thyroid, adrenal cortex dysfunction, diabetes, Sheehan's disease, etc.; liver diseases; blood diseases, etc. The use of psychiatric medications; endocrine preparations, or the use of intrauterine devices for contraception may all 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.
