At what age does a woman get her period?

As women age, they will have menstruation, and the menarche also symbolizes the development of women's bodies, indicating that women at this time have entered puberty. Women with different physiques have different ages of menstruation. Only by ensuring a healthy body can menstruation come normally, otherwise it will cause menstruation to be delayed. So at what age does a woman have her period?

First, at what age does a woman start her period? It is normal to start menstruating between the ages of 10 and 16. Most healthy Oriental girls start menstruating between the ages of 10 and 16. Those who start menstruating before the age of 10 are considered precocious puberty, and those who have not started menstruating by the age of 18 are called primary amenorrhea, both of which are abnormal phenomena. Note! However, due to the influence of climate and geographical location, women in some areas may not have their first menstruation until after the age of 18, which is also normal.

Second, menarche is affected by many factors, the following are some of the more common factors. Due to the influence of climate and geographical location, girls living in warm areas have more comfortable living conditions and their menarche occurs earlier. In some cold areas, such as the Eskimo women in northern Taiwan, menstruation does not begin until the age of 23. The average age of menarche for Tibetan girls in Tibet, my country is 17.6 years old.

Third, girls in developed countries in Europe and America have their menarche earlier, while in developing countries it is later. Girls in urban areas have their menarche earlier, while girls in rural and remote areas have their menarche later. This is mainly because developed countries or cities have more developed economies and pay more attention to nutrition and diet. Taking my country as an example, in 1980, the age of menarche for women in first-tier cities was 13.7 years old. In 1993, a survey conducted by the Women and Children's Health Center of Peking University Medical School showed that the age of menarche for women in cities was 12.62, while that in rural areas was 13.07.

Fourth, studies have shown that women will have their first menstruation when their body fat reaches 17%. When it is lower than 15%, their menstruation will be delayed or even absent. When body fat is higher than 30%, there will be endocrine disorders, no menstruation or heavy menstruation, and prolonged menstruation.
