Amenorrhea in adolescent girls is actually reproductive tract atresia

　　amenorrhea yes Gynecology A common symptom, not a disease . Medically speaking, the absence of menstruation after the age of 18 is called primary amenorrhea, and the absence of menstruation for more than three months after normal menstruation is called secondary amenorrhea.

　　The causes of amenorrhea are many and complex. It can be caused by many systemic or local organic or functional sexually transmitted diseases Caused by changes, it may also be the prodromal symptom of certain diseases and should not be taken lightly. And before puberty, pregnancy, lactation and menopause Post-period amenorrhea is a normal physiological phenomenon.

　　Women must get regular sex as soon as possible after amenorrhea Hospital Conduct detailed and systematic gynecological examination and B-ultrasound examination. If necessary, diagnostic dilation and curettage and sex hormone measurement are performed; sometimes a comprehensive physical examination and thyroid, adrenal or pancreatic function tests are also indispensable in order to identify the cause and provide symptomatic treatment. If you just want to save trouble, blindly seeking medical treatment will undoubtedly make things worse.

　　The establishment of a normal menstrual cycle relies on the following prerequisites:

　　1、female Reproductive organs develop normally;

　　2、Uterus The endometrium responds cyclically to sex hormones;

　　3. The hypothalamic-pituitary-ovarian axis regulation function is normal. Failure in any of the above links, whether organic or functional, can lead to amenorrhea.

　　There are many causes of amenorrhea, the common ones are the following:

　　disease

　　wasting diseases, such as severe tuberculosis, severe anemia , malnutrition, etc.; unique endocrine diseases, such as "obesity reproductive infertility dystrophy", etc.; effects of some endocrine glands in the body, such as adrenal glands, thyroid, pancreas and other functional disorders. Due to the influence of these factors, menstruation often does not occur. For amenorrhea caused by these conditions, as long as the disease is cured, menstruation will come naturally.

　　Atresia of the lower reproductive tract

　　For example, if there is a section of congenital atresia in the cervix, vagina, hymen, labia, etc., or adhesion atresia caused by acquired damage, although menstruation occurs, menstrual blood cannot flow out. This situation is called latent or pseudoamenorrhea. Atresia of the lower reproductive tract is completely curable with medical treatment.

　　Imperfect or underdeveloped reproductive organs

　　Some women are congenitally without ovaries, or have underdeveloped ovaries, or have damaged ovaries and cannot produce estrogen and progesterone. Therefore, the endometrium cannot undergo cyclic changes, and there will be no endometrial shedding, so there will be no menstrual cramps. There are also cases where the uterus is congenitally absent, the endometrium is underdeveloped, or the endometrium is damaged. Even if the ovaries are functional and estrogen and progesterone are secreted normally, menstruation will not occur.

　　Tuberculous endometritis and abnormal pituitary and hypothalamic function

　　There are many reasons for hypothalamic dysfunction, such as mental stimulation, sadness and worry, fear and uneasiness, tension and fatigue, environmental changes, cold stimulation, etc. Amenorrhea caused by the hypothalamus is more common.
