At what age does a girl's menarche occur?

Due to the lack of knowledge of some common sense of physiological health, many girls do not know the age of menarche, and even do not pay attention to their own physical health during this process, so they are easily affected by some diseases. So let us understand the general age range of girls' menarche. Girls at this time must pay attention to observation.

Menarche and subsequent menstruation may not occur with ovulation. But there are rare cases where ovulation occurs one to two weeks before menarche. The average age of first menstruation for Oriental women is between 12 and 16 years old. The statistics in different countries vary slightly, which is related to eating habits and climate. In rare cases, menarche occurs very early, before breast development and other pubertal development. This symptom is called premature menarche. Other possible causes of bleeding must be ruled out before diagnosing this symptom.

According to relevant statistics in our country, most girls have their first menstruation between the ages of 12 and 16. For example, from 1978 to 1980, relevant units conducted a survey on the menstrual conditions of 130,000 women in 29 provinces, municipalities, and autonomous regions across the country and found that the youngest age of menarche was 9 years old and the oldest was 21 years old. The vast majority were between 12 and 19 years old, with an average of 15 years old. The most common age of menarche for urban women is 15 years old, while for rural women it is 16 years old. Another survey data from 1978-1979 showed that the earliest average age of menarche was in Guangzhou and Beijing, at 13.3 and 13.6 years old respectively; the latest was in Shandong, at an average of 15.4 years old.

Menarche is a normal physiological change for girls, which means that they have stepped into the threshold of becoming a woman. So when facing this kind of thing, don't panic. Tell yourself that this is very important and something to be proud of. At the same time, remind yourself to do a good job of various care and reproductive health work during the menstrual period.
