Girls will start menstruating when they reach a certain age, and the time of the first menstruation will vary depending on the individual's physical condition.

Is it normal to have menstruation at the age of eleven?

Generally speaking, it is normal for most healthy women in our country to have menstruation between the ages of 10 and 16. Menarche before the age of 10 is considered precocious puberty, and no menstruation at the age of 18 is called primary amenorrhea, both of which are abnormal. However, due to certain special climates or geographical locations, women in some areas may not have their first menstruation until after the age of 18. This is normal and there is no need to worry too much.

Factors that affect the timing of menarche

1. 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. 2. Nutritional status affects girls. 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.
