Are there any other complications of amenorrhea?

Patient's question:

Suffering from amenorrhea for 2 months

Doctor's answer:

Uterine Amenorrhea: Caused by the endometrium not responding to or poorly responding to hormones. It is commonly seen in conditions such as endometrial tuberculosis, endometrial damage (e.g., no regeneration of the uterine lining after curettage), endometrial adhesions, and endometrial hypoplasia. In such cases, even with artificial hormonal regulation (artificial cycle), the endometrium will not shed and bleed.
Ovarian Amenorrhea: Primarily caused by ovarian diseases. Due to abnormally low estrogen levels, the endometrium cannot grow, as seen in congenital ovarian hypoplasia, premature ovarian failure, and unresponsive ovaries. In these individuals, estrogen levels are low while gonadotropin levels are normal or elevated, and artificial cycle treatment can be applied.
Pituitary Amenorrhea: Amenorrhea is associated with pituitary dysfunction and can be observed in cases such as cranial trauma, Sheehan's syndrome, and cranial radiation therapy.
Hypothalamic Amenorrhea: The issue lies in the hypothalamus. It can be caused by organic neurological diseases, such as inflammation, tumors, or ischemia, or by psychological factors, environmental changes, systemic diseases, malnutrition, and medication effects.
