Can an 11 years old get taller after the period?

Yes, an 11-year-old can still grow taller after starting their period. Growth plates in bones remain open for several years after menstruation begins, allowing for continued height increase. The rate and amount of growth vary by individual and depend on factors like genetics and nutrition. Generally, girls may experience most of their growth spurts before and shortly after their first period, but some growth can occur afterward as well.
