If the menstrual disorder is caused by endocrine factors, it may lead to elevated progesterone, which may lengthen the menstrual cycle accordingly, cause menstruation to be delayed frequently and may lead to an increase in the amount of menstruation. In case of menstrual disorders, it is recommended to take a blood test for sex hormone 6, mainly on the second or third day of menstruation to find out whether progesterone, estradiol, follicle stimulating hormone, androgen and prolactin are abnormal to cause menstrual disorders, and the result should be referred to the follicular phase. If there are abnormalities, it is recommended that the endocrine results should be used to regulate and treat accordingly. In addition, people with irregular menstruation should live a regular life and develop good living habits to minimize the endocrine impact.
