The cause of primary dysmenorrhea needs to be analyzed for everyone

Primary dysmenorrhea is a type of dysmenorrhea. There are many causes of primary dysmenorrhea. So what are the causes of primary dysmenorrhea? Primary dysmenorrhea is already affecting the normal life of patients. Now, let the experts introduce to you the causes of primary dysmenorrhea .

1. Age is an important cause of primary dysmenorrhea. Dysmenorrhea rarely occurs in the first few months of menarche, and then the incidence rate increases rapidly, reaching a peak (82%) at the age of 16-18, and gradually decreases after the age of 30-35, stabilizing at around 40% in the middle of the reproductive age, and then even lower, maintaining at 20% at the age of 50. The start of sexual life can reduce the incidence of dysmenorrhea.

2. Childbirth is another important cause of primary dysmenorrhea. The incidence and severity of dysmenorrhea in women with a history of full-term pregnancy and childbirth are significantly lower than those without a history of pregnancy or those who have a pregnancy but have a spontaneous abortion or artificial abortion. In addition, women with early menarche or long menstrual periods and heavy menstrual flow have severe dysmenorrhea. The incidence of dysmenorrhea is significantly reduced in those who take contraceptives. Dysmenorrhea also shows certain family characteristics. The mothers and sisters of dysmenorrhea sufferers often have dysmenorrhea.

3. Special occupations and working environments are also related to the cause of primary dysmenorrhea. Women who have long-term exposure to mercury and benzene compounds (even at low concentrations) have an increased incidence of dysmenorrhea. A cold working environment is also related to dysmenorrhea.

4. Mental factors also have an impact. Mental factors are also very important for women with dysmenorrhea. They often show poor self-regulation, depression, anxiety and introversion. Those with severe dysmenorrhea are more feminine in terms of interests and emotions than those without dysmenorrhea. Some people also believe that mental factors only affect the response to pain, rather than pathogenic factors.

5. Abnormal uterine contraction. The occurrence of primary dysmenorrhea is related to increased uterine tension and excessive spasmodic contraction caused by increased uterine muscle activity, which is also the cause of primary dysmenorrhea.
