Is it normal to start menstruation at age eleven, and is it still possible to grow taller?

Generally, it is normal for an 11-year-old girl to start menstruation. After the onset of menstruation, there is still potential for further height growth. If concerned, it is recommended to consult a healthcare professional. Detailed analysis is as follows:

1. Is it normal for an 11-year-old girl to start menstruation?

Typically, girls begin menstruation between the ages of 10 and 14. With improvements in nutrition and changes in lifestyle, the onset of puberty has shown a trend toward earlier ages. If an 11-year-old girl begins menstruating without other abnormal symptoms, this is considered a normal physiological occurrence and does not require excessive concern.

However, if a girl develops secondary sexual characteristics—such as breast development or onset of menstruation—before the age of eight, especially accompanied by excessive physical development, this may indicate precocious puberty, and prompt medical evaluation is advised.

2. Can an 11-year-old girl still grow taller after starting menstruation?

A girl's height increase is related to whether the growth plates (epiphyseal plates) have closed. Height growth typically continues for several years after the first menstrual period, until the growth plates fully close. Generally, an 11-year-old girl can still grow taller after starting her periods.

However, after menstruation begins, she enters the later stages of puberty, and the rate of height growth may slow down. It is recommended to promote optimal height development through balanced nutrition, moderate physical activity, and sufficient sleep.

During puberty, maintaining a well-balanced diet, engaging in regular physical exercise, and ensuring adequate intake of calcium and high-quality proteins can support healthy height growth.
