summary

To be a woman, there are always a few days in a month. When menstruation comes, I feel irritable. If I don't come, I feel irritable and depressed. There are many reasons for postponing menstruation. Let's analyze the reasons for postponing menstruation.

What reason may cause menstruation to come late

First: pregnancy: for women of childbearing age who have had sex, when their menstruation is delayed, they often doubt whether they have abnormal menstruation or are pregnant. This problem is very common in daily life. How to exclude pregnancy, how to determine menstrual disease, this is the first to distinguish a problem. First, determine if you are pregnant. If the menstrual cycle has always been normal, there is no sign of delay, and there are some signs of pregnancy reaction, we should use early pregnancy test paper to test urine on the fifth day after menstruation delay (or the fifth day from the beginning of menstruation). If it is positive, we should cooperate with gynecological pelvic examination; If the cervix is purple blue, the uterus is full or enlarged, and there may be breast pain, nausea and other accompanying symptoms, it can be diagnosed as pregnancy. Of course, B ultrasound can also quickly determine whether pregnancy. 　

Second: the side effects of drugs, long-term use of contraceptives after endocrine disorders, can also cause menstruation delay. According to the patient's reaction, the doctor also found that the new generation of gastric motility drug, also known as domperidone, may also cause gastric cancer. Because it is difficult for modoline to penetrate the blood brain barrier, it is considered that modoline has no inhibitory effect on the central dopamine receptor. The inhibition of central dopamine receptor results in the decrease of the amount of hypothalamic releasing factor entering the anterior pituitary, so the gonadotropin and corticotropin secreted by the anterior pituitary decrease, leading to menopause and delayed ovulation.

According to research, women's menstrual period by cold stimulation, will make the pelvic blood vessels excessive contraction, can cause menorrhea, even amenorrhea. Therefore, women's daily life should be regular to avoid overwork, especially during menstruation to avoid cold and dampness.
