Warning: Common causes of primary dysmenorrhea

Primary dysmenorrhea is a type of dysmenorrhea with a high incidence rate. It seriously endangers the health of patients and brings many inconveniences to the lives of female friends. What are the causes of primary dysmenorrhea ? Here are some common causes of primary dysmenorrhea.

In general, the common causes of primary dysmenorrhea are:

1. Vasopressin (AVP) factor

It is known that vasopressin containing arginine can cause strong contraction of the uterus of non-pregnant women, and the local blood flow decreases significantly. The plasma concentration of AVP and the responsiveness of the uterus to it vary with the menstrual cycle. It is most sensitive at the beginning of menstruation. The plasma AVP concentration of patients with primary dysmenorrhea on the first day of the menstrual cycle is significantly increased, which is 1-4 times that of the control group. In addition, the use of desaminoethyl oxytocin to competitively inhibit the effect of AVP on the uterus can significantly relieve the symptoms of primary dysmenorrhea. Therefore, AVP may also be an important factor in primary dysmenorrhea.

2. Spiritual national qualities

Primary pain often occurs in women who are not mentally mature and have neurotic personalities. Some girls do not have enough knowledge about menstrual physiology and feel fear and anxiety when their period is approaching. Adverse stimuli such as stressful study and work, sudden changes in the environment, and unhappy moods can cause primary dysmenorrhea through the hypothalamus-pituitary-ovarian axis, which leads to changes in hormones in the body. However, studies in recent years have shown that it is difficult to attribute the occurrence of primary dysmenorrhea to mental factors, which can have a certain impact on acute and chronic pain in any part of the body. Mental factors have no unique effect on primary dysmenorrhea, so this factor has not been taken seriously.
