Why do some women with postpartum hemorrhage experience amenorrhea?

Under normal circumstances, there is a varying amount of vaginal bleeding during childbirth, with an average of 150 to 300 ml of bleeding. However, when the total amount of bleeding exceeds 500 ml within 24 hours after the birth of the fetus, it is called postpartum hemorrhage, accounting for 1% to 2% of the total number of births and is one of the major causes of maternal death. If some women do not receive blood transfusions in time when they have postpartum hemorrhage and shock, it can often lead to ischemic necrosis of the anterior pituitary gland and anterior pituitary insufficiency, which is called "Sheehan's syndrome."

The anterior pituitary gland can produce a variety of trophic hormones to regulate the body's metabolism. When the anterior pituitary gland is insufficiency, one or several trophic hormones may be deficient, and corresponding symptoms may appear. The organs commonly affected are the adrenal glands, ovaries, and thyroid glands. Patients with postpartum hemorrhage may experience decreased or absent postpartum milk secretion, long-term amenorrhea, breast and genital atrophy, fatigue, weakness, chills, edema, hair loss, etc. after a period of delivery, depending on the degree of damage to the anterior pituitary gland.

Therefore, for those who have amenorrhea or other symptoms mentioned above after postpartum hemorrhage, they should go to the hospital for examination in time and adopt appropriate treatment according to the severity of the disease. If the disease is mild and only affects one organ, it is possible to restore its function with early active treatment; if the disease is severe and has affected multiple organs, supplementary treatment with drugs is needed to alleviate symptoms and restore labor.

For patients whose gonads are simply affected and whose condition is mild, if they wish to restore their reproductive function, they can use some drugs that promote ovulation to restore the reproductive function of the ovaries.
