Menarche and its relation to growth plates?
My daughter has just entered fifth grade and seems to be experiencing signs of menarche.
I've heard that this could mean her height will no longer increase.
Is this true? She is currently about 145 cm tall.
Does she need to see a Western medicine doctor for medication or have her growth plates examined? Should we consult an orthopedic specialist?

If precocious puberty occurs (defined as the appearance of secondary sexual characteristics in females before age 8, such as breast development and the emergence of pubic and axillary hair; or menstruation before age 10), adult height may be shorter than average.
If there is no precocious puberty, height will not be abnormal.
If necessary, a consultation with a pediatric endocrinologist may be warranted.

When it comes to understanding menstruation and growth plate concerns in children, especially in the context of your daughter who has recently started menstruating at a young age, there are several important factors to consider.
Firstly, the onset of menstruation, or menarche, can indeed be an indicator of the onset of puberty. In girls, this typically occurs between the ages of 9 and 16, with the average age being around 12. If your daughter has started menstruating at the beginning of fifth grade, this could be considered early onset of puberty, also known as precocious puberty. This condition can sometimes lead to concerns about growth, as the growth plates (epiphyseal plates) in the bones tend to close earlier in girls who experience early puberty.
The growth plates are areas of developing cartilage tissue near the ends of long bones. They are responsible for the lengthening of bones during childhood and adolescence. Once a girl begins menstruating, it is often thought that her growth may slow down or stop altogether, as the growth plates may close soon after. However, this is not a definitive rule, as growth patterns can vary significantly among individuals. Some girls may continue to grow for a few years after their first period, while others may not.
Regarding your daughter's height of approximately 145 cm, it is essential to monitor her growth over time. If you have concerns about her growth potential, it may be beneficial to consult a pediatrician or an endocrinologist who specializes in growth and puberty. They can assess her growth pattern, family history, and overall health.
As for the question of whether to pursue medical interventions such as medications or imaging studies like X-rays to examine the growth plates, this decision should be made in consultation with a healthcare professional. If there are concerns about her growth trajectory or if she is significantly shorter than her peers, a doctor may recommend an X-ray to evaluate her bone age and the status of her growth plates. This can provide valuable information about her growth potential.
In terms of dietary supplements or "tonics" marketed for growth, it is generally advisable to focus on a balanced diet rich in essential nutrients rather than relying on over-the-counter products. A well-rounded diet that includes adequate protein, calcium, vitamin D, and other vitamins and minerals is crucial for healthy growth and development.
In summary, while early menstruation can be associated with earlier closure of growth plates, it does not guarantee that your daughter will stop growing immediately. Consulting with a healthcare professional can provide clarity on her growth potential and whether any further evaluations or interventions are necessary. Regular monitoring of her height and overall health will be key in addressing any concerns about her growth and development.
