One: Emotional abnormality
Emotional abnormality is one of the common causes of irregular menstruation in women. Long-term mental depression, sulking, or severe mental stimulation and psychological trauma will lead to menstrual disorders, or dysmenorrhea and amenorrhea.
Because menstruation is a hormone secreted by the ovary, and the hormone secreted by the ovary after stimulating the endometrium is controlled by the hormones released by the pituitary and hypothalamus, the abnormal function of the pituitary and hypothalamus will affect menstruation.
Two: the stimulation of cold
Cold stimulation can cause oligomenorrhea, even amenorrhea, because cold stimulation during menstruation can cause excessive contraction of pelvic blood vessels, resulting in decreased menstrual blood. Therefore, female friends should avoid overwork in daily life, especially during menstruation, and don't wear less clothes because they love beauty, which is not good for their health.
Three: excessive dieting
Excessive dieting is also one of the common causes of irregular menstruation in women. Teenage girls' fat accounts for at least 17% of their pre-menarche weight, while body fat reaches at least 22% of their body weight to maintain normal menstrual cycle.
Many women who love beauty and lose weight over-diet, resulting in insufficient energy intake, resulting in a large amount of fat and protein consumed in the body, leading to estrogen synthesis disorder, obvious lack, affecting menstrual cramps, even thin menstruation, or amenorrhea.
Four: constipation
Constipation can also lead to irregular menstruation in women. After the stool in the rectum is overfilled, the cervix will be pushed forward and the uterus will lean backward. If the uterus contracts repeatedly for a long time, the veins in the broad ligament will be compressed and blocked, and the uterine wall will be congested and lose elasticity, causing low back pain and menstrual disorder.
