Heavy periods

Menorrhagia is defined as heavy menstrual bleeding during consecutive menstrual cycles, but menstrual intervals and bleeding time are regular, with no bleeding between menstruation, bleeding after sexual intercourse, or a sudden increase in menstrual blood. Clinically, the bleeding time is compared with the basal body temperature (BBT) curve, and ovulatory dysfunctional uterine bleeding is divided into two types: heavy menstrual flow and intermenstrual bleeding.

Cause

1. Caused by neuroendocrine dysfunction

The main reason is that the function of the hypothalamus-pituitary-ovarian axis is unstable or defective.

2. Caused by ovarian problems

Irregular menstruation in women of childbearing age is generally due to poor ovarian corpus luteum function, often showing more menstrual bleeding.

3. Caused by organic disease or drugs

Including local inflammation, tumors and dysplasia of the reproductive organs, malnutrition; intracranial diseases; other endocrine dysfunctions, such as thyroid and adrenal cortex dysfunction, diabetes, Sheehan disease, etc.; liver diseases; blood diseases, etc. Menorrhagia may occur in people who use psychotropic drugs, endocrine preparations or take intrauterine contraceptive devices for contraception.

Clinical manifestations

Menorrhagia patients lose more than 80ml of blood per menstrual cycle. The criteria for subjectively judging the amount of bleeding vary greatly from patient to patient. It has been reported that only 40% of patients who complained of heavy menstruation lost more than 80ml of blood loss through objective measurement.

月经多 月經多

月经过多的定义是连续数个月经周期中月经期出血量多，但月经间隔时间及出血时间皆规则，无经间出血、性交后出血、或经血的突然增加。临床上以出血时间与基础体温（BBT）曲线对照，将有排卵型功能失调性子宫出血分为月经量多与经间出血两类。
