What are the symptoms of functional uterine bleeding?

Functional uterine bleeding is a common gynecological disease, abbreviated as functional uterine bleeding, which actually refers to abnormal uterine bleeding in women. The causes of functional uterine bleeding can be divided into two categories. The first is nervous system disorders, and the second is endocrine dysfunction, which leads to abnormal menstruation in women, resulting in the following symptoms of functional uterine bleeding.

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 menstrual period is normal at the beginning, but the bleeding becomes light and lasts longer in the later stages. 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 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:

It is an abnormal bleeding that often occurs during 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.
