Patient's question:
Detailed medical condition and consultation purpose: 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 a heavier flow. I am 28 years old, have given birth, and have been using an IUD for nearly three years. I enjoy exercising, and I don’t know what caused this change.Duration and course of the current illness: 4 months
Current general condition: No discomfort is felt.
Medical history: None.
Previous diagnoses and treatments, as well as their effectiveness: None.
Ancillary examinations: Normal results from an ultrasound.
Doctor's answer:
1. Neuroendocrine dysfunction causes: Mainly the instability or defects in the function of the hypothalamus-pituitary-ovary 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; nutritional deficiencies; intracranial disorders; other endocrine dysfunctions such as abnormal thyroid or adrenal cortex function, diabetes, Sheehan's disease, etc.; liver diseases; blood disorders, 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.
