delayed period
Introduction
Introduction Delayed menstruation after menstruation is delayed, and women's menstrual cycle is generally 28 to 30 days. It is still within the normal range of 7 days in advance or delayed, and the length of the cycle varies from person to person. However, if menstruation has not come after 7 days, it is delayed. Chinese medicine believes that the water is out of the kidneys, pointing out that menstrual disease and kidney function are related, and the spleen, liver, qi and blood, rushing pulse, Renmai, and uterus are also related. There are two main types: one is deficiency syndrome, which is caused by qi and blood weakness or liver and kidney loss. Such people should pay attention to supplementing, tonifying Qi and nourishing liver and kidney. The second is empirical evidence, that is, "nothing is painful", which is caused by poor blood flow. Such people should be relieved of pain and pain.
Cause
Cause
1, pregnancy
After menstruation is delayed for 7 days in menstruation, the urine can be tested with "pregnancy test strips". If it is positive, it is very likely to be pregnant. "Pregnant test strips are negative". But if it is pregnant, there will be other symptoms, such as nausea and breast pain. Of course, the final solution is to go to the hospital for a B-ultrasound.
2, the role of the drug
Endocrine disorders after long-term use of contraceptives can also cause menstrual delays. Because gastric motility drugs do not easily penetrate the blood-brain barrier, they are considered to have no inhibitory effect on central dopamine receptors. The central dopamine receptor is inhibited, resulting in a decrease in the amount of hypothalamic release factor into the anterior pituitary. Therefore, the gonadotropin and corticotropin secreted by the anterior pituitary are reduced, leading to menopause and delayed ovulation.
3, caused by surgery
For example, intrauterine surgery causes cervical adhesions and blood stasis, which delays menstruation.
4, other
Such as mental stress, stress, environmental changes and other psychological factors, some diseases that affect endocrine. Can cause delayed menstruation.
