Is it normal for an 11-year-old girl to have her period?

Girls have always needed menstruation, which is also one of the signs that girls have just begun sexual development. Many girls are still ignorant when they have their first period and don't know what it is. At this time, they need their parents to give them proper guidance, so that they can gradually master sex and how to protect themselves as soon as possible. Is it normal for a girl to have her period at the age of 11?

Is it normal for a girl to have her period at the age of 11?

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 onset age of all sexual development characteristics is more than 2 standard deviations earlier than the age structure of normal children. In other words, the onset age of children's sexual development is significantly earlier than the age structure of normal children, which is called precocious puberty. The youth development age of children in our country is constantly increasing. At present, precocious puberty in my country is still defined as the secondary sexual characteristics of girls before the age of 8, the secondary sexual characteristics of boys before the age of 9, or the menstruation of girls before the age of 10. Precocious puberty is more common in girls, with a sex ratio of about 1:4. The pathogenesis of precocious puberty of the central nervous system in children and adolescents is complex and closely related to neuroendocrine effects. The increase in the frequency and intensity of growth hormone pulses released by the hypothalamus-pituitary gonadotropin is an important sign of human growth and development entering adolescence. For some reasons, the hypothalamic-pituitary-gonadal axis may be stimulated prematurely, and the single pulse release of gonadotropin and growth hormone is significantly increased, resulting in precocious puberty of the central nervous system. In addition, organic diseases of the central nervous system will directly affect the regulatory mechanism of the gonadotropin-releasing growth hormone pulse counter and cause symptoms. In addition to genetic factors, the occurrence of precocious puberty is also related to environmental factors (including social, economic and nutritional factors). In addition, natural environmental estrogen pollution may also be related to this.
