I haven't had my period for a few months, and it comes in the morning and disappears by the evening.

Patient's question:

Approximately 4 months of duration, with a decrease in amount during the day, dripping and depleting, dark complexion with spots, weight gain, fear of cold, no desire to have a baby unable to conceive

Doctor's answer:

Hello, as you described, generally, a small amount of menstrual flow refers to a reduced volume of blood during menstruation compared to the normal range. It is often caused by factors such as blood deficiency, qi stagnation, blood stasis, blood vessel cold congelation, or phlegm obstruction. This condition is equivalent to functional uterine bleeding, polycystic ovary syndrome, premature ovarian failure, or intrauterine adhesions after an induced abortion or significant blood loss, among other diseases in Western medicine.
