Girls have been having their periods all the time, which is one of the signs that they have just started their sexual development. Many girls are still ignorant when they just get their period, and don't know what it is. At this time, parents need to give them proper guidance, so that they can gradually understand the things about sex and how to better protect themselves. Is it normal for a girl to have her period at the age of eleven? Is it normal for a girl to have her period at the age of eleven? Because it is puberty now, due to the immature ovaries and the young age, the endocrine system has not yet reached a stable state, and the menstrual period may not be normal for a period of time. Nowadays, many girls have symptoms such as gluttony, bad temper, abdominal and waist pain before their period. It is estimated that it is time for their period when they are 13 or 14 years old. Now they have started to have leucorrhea (the light yellow sticky substance on the underwear is secretion), so you must pay attention to hygiene, wash more often, and be careful not to catch cold often. You can use sanitary napkins sometimes, but don't use it every day. If it is the first time, you must pay attention to catching a cold. If you catch a cold for the first time, it may cause menstrual pain in the future, but this also varies from person to person. In short, no matter what, there is no need to worry about the menstrual period, this is something that women must have. During puberty, when a girl's uterus and ovaries develop fully, about one perfect egg is released from the uterus and ovaries every month. If the egg is not fertilized, the uterine wall will naturally fall off, causing abnormal uterine bleeding (when the endometrium falls off, you will feel abdominal pain and back pain), which is the menstrual period. The first time you have your period is called your first menstruation. Girls usually have their first period between the ages of 11 and 17. The menstrual cycle is the same as the ovulation cycle of the uterus and ovaries, which is about 28 to 30 days. Generally speaking, girls' breasts begin to enlarge when they are about 11 years old, and boys' pubic hair begins to grow and develop when they are about 12 years old. The early 12 years old is the peak period of growth and development. The middle and late 12 years old is the period of body change, the early 13 years old is the period of armpit hair growth and development, and the middle and late 13 years old is the period of menarche for girls. Precocious puberty The age at which all sexual development characteristics first appear is more than 2 standard deviations earlier than the normal age structure of children. In other words, the age at which children's sexual growth and development start is significantly earlier, which is called precocious puberty. The age of puberty among children in my country is continuously being advanced. Currently, my country still defines precocious puberty as the appearance of secondary sexual characteristics in girls before the age of 8, in boys before the age of 9, or the onset of menstruation in girls before the age of 10. Precocious puberty is more common in girls, with a sex ratio of approximately 1:4. The pathogenesis of precocious puberty of the central nervous system in children and adolescents is relatively complex and is closely related to neuroendocrine effects. The increase in the frequency and intensity of the single pulse of gonadotropin-releasing hormone is an important sign that the body has entered puberty. Due to some reasons, the hypothalamic-pituitary-gonadal axis may be activated prematurely, and the single pulse of gonadotropin-releasing hormone is significantly increased, resulting in precocious puberty of the central nervous system. In addition, organic diseases of the central nervous system can also directly disrupt the control mechanism of the gonadotropin-releasing growth hormone pulse counter and cause illness. In addition to genetic factors, the occurrence of precocious puberty is also related to environmental factors (including social development, economic development, nutrition). In addition, the problem of estrogen pollution in the natural environment may also be related to it. |
