What are the symptoms of uterine bleeding?

Uterine bleeding is excluded as normal bleeding during menstruation, and bleeding after the menstrual period is abnormal uterine bleeding. Sometimes the blood flows and sometimes stops, and sometimes the amount of blood is more and sometimes less. There is generally no pain when there is no ovulation blood supply, but excessive blood loss is often accompanied by anemia.

1. Ovulation bleeding : Due to the low estrogen level before ovulation, a small amount of vaginal bleeding can be seen during the ovulation period.

2. Premenstrual bleeding : There is a small amount of vaginal bleeding a few days before menstruation, followed by normal menstruation. This type of bleeding is caused by luteal insufficiency and insufficient secretion of estrogen and progesterone.

3. Postmenstrual bleeding : The initial stage of menstruation is normal, but in the later stage, the bleeding is small and lasts longer. This type of bleeding is characterized by incomplete endometrial exfoliation and a mixture of incompletely exfoliated secretory endometrium and early proliferative endometrium. This is mainly due to the slow regression of the corpus luteum and the continuous secretion of progesterone.

4. Bleeding caused by endometrial hyperplasia : It is a typical anovulatory bleeding. Due to the continued existence of follicles and the secretion of a certain amount of estrogen, the endometrium proliferates abnormally, and the endometrium often shows glandular cystic hyperplasia.

5. Bleeding caused by incomplete endometrial maturation : This is a type of abnormal bleeding that is common in the luteal phase. Endometrial proliferative and luteal phase changes may exist simultaneously. It is caused by an imbalance in the secretion of estrogen and progesterone.
