Irregular menstrual cycle, suddenly very little flow, what is the reason?

Patient's question:

Irregular period, suddenly the amount is very little

Doctor's answer:

The causes of menstrual disorders can be divided into two major categories:
1. Neuroendocrine dysfunction-induced: Primarily due to instability or defects in the hypothalamic-pituitary-ovarian axis, which is known as menstrual disorders.
2. Organic lesions or drug-induced: Including local inflammation, tumors, and developmental abnormalities of the reproductive organs; malnutrition; intracranial disorders; other endocrine dysfunctions such as abnormal thyroid, adrenal cortex function, diabetes, Sheehan's disease, etc.; liver disorders; blood disorders, etc.
It is recommended to seek medical examination and treatment at a formal hospital to rule out the possibility of organic lesions, in order to avoid delaying normal work and life!
