Patient's question:
Menstruation came on the 8th, and it's been until the 19th of this month without arriving. Is this a normal phenomenon?What kind of help do you want:
Tell me what might be the reason for this?
Doctor's answer:
The reasons for a prolonged menstrual cycle may include hypofunction of the hypothalamic-pituitary-ovarian axis, which shortens the follicular maturation phase, or abnormal menopausal function. Pituitary tumors and patients with polycystic ovary syndrome often experience infrequent menstruation or amenorrhea due to hypofunction or imbalance of pituitary gonadotropins. Hypothyroidism leading to slow metabolism can also prevent the ovaries from undergoing timely menopause. It could also be caused by pregnancy. It is recommended to undergo relevant gynecological examinations at a regular hospital.
