11-year-old girl's menstrual symptoms

The physical development of girls is a gradual process. Normally, girls will start menstruating when they are around 11 or 12 years old. Menstruation is also an important proof of the rapid development of the female body, so girls in this period should not feel ashamed to talk about the phenomenon of menstruation. For an 11-year-old girl, the body generally shows the following signs before menstruation.

Nowadays, many girls will experience reactions such as craving for food, bad temper, soreness in the abdomen and waist before their period. It is estimated that it is time for their period to come at the age of 13 or 14. If they start to have leucorrhea now (the yellowish and sticky thing on the underwear is leucorrhea), then you must pay attention to hygiene, wash and change your underwear frequently, and be careful not to catch cold often. Sometimes you can use sanitary pads, but don't use them every day. If it is your first time, you must pay attention to catching a cold. If you catch a cold for the first time, it may cause dysmenorrhea in the future, but this also varies from person to person. Anyway, no matter what, there is no need to be afraid of menstruation, it is something women must have.

When a girl enters puberty, her ovaries mature and about one mature egg is released from the ovaries every month. If the egg is not fertilized, the endometrium will fall off naturally, causing uterine bleeding (when the endometrium falls off, you will feel abdominal pain and back pain), which is menstruation. The first menstrual period is called menarche. The age of menarche is generally between 11 and 17 years old. The menstrual cycle is the same as the ovarian ovulation cycle, about 28 to 30 days.

Generally speaking, girls' breasts begin to enlarge before the age of 11, and their pubic hair begins to grow when they are almost 12, with the growth peak occurring before the age of 12. The middle of 12 years old is the period of body shape change, the early 13 years old is the period of armpit hair growth, and the middle of 13 years old is the period of menarche.

⑴ Mainly mental symptoms: common symptoms include nervous sensitivity, irritability, general fatigue, and sometimes headaches, insomnia, and lack of concentration.

⑵ Mainly physical symptoms: common symptoms include swelling of hands, feet and face, abdominal bloating, abdominal distension in some people, constipation in most girls, lower abdominal pain and breast pain, etc.

The early or late menarche is also related to the climate. Generally speaking, girls in tropical regions with high temperatures have their first menstruation earlier, while girls in cold regions have their first menstruation later. This may be related to the pineal gland in the human brain. The pineal gland secretes a hormone called melanocytic antagonist. In recent years, it has been discovered that the secretion of melanin is related to light. It is secreted more in the dark, and has a stronger inhibitory effect on the gonads; it is secreted less in the light, and has a weaker inhibitory effect on the gonads. This provides a scientific explanation for the phenomenon that people in tropical regions mature earlier.

In addition, the early or late menarche is also related to physical health, mood, nutrition, etc. In short, the early or late menarche is affected by many factors, so individual differences may be large. Menstruation can occur as early as 9 years old or as late as 18-19 years old if there are no other abnormal conditions. If you have your period at the age of seven or eight, or have not had your period at the age of 22, and have other symptoms, you should go to the hospital to find out the cause and receive treatment as soon as possible. The menarche of a girl is merely a sign that the reproductive system has begun to work. The function of the reproductive system is not yet mature, so during the period of menarche, the menstrual cycle is often irregular. According to a survey, it takes most people more than half a year from the first menstruation to the second menstruation, and some even take eight or nine months. Menarche turns into a normal menstrual cycle, usually within two years. You must have a full understanding of this phenomenon of irregular menstrual cycles. Don't think that you are sick and take medicine indiscriminately to avoid affecting your health.
