There is no authoritative information on how tall you can grow at 12 years old 1 meter 55 menstruation, but generally women can still grow 5 to 7 centimeters at puberty, mainly related to whether the epiphysis is closed. The 12-year-old female menstruation indicates to enter into the puberty, indicating that the basic development of the ovaries mature. However, there is no authoritative information on how much taller a 12 year old 1 meter 55 years old can grow after menstruation, mainly because there is obvious individual variability in the height growth and development of the first menstrual period, and cannot be generalized. In general, 12 years old 1 meter 55 after menstruation can still grow 5 to 7 centimeters. The growth of height is not only related to the early and late sexual maturity, but also related to genetics, exercise, nutritional intake and other factors. Therefore, as long as the epiphysis of 12-year-old women has not closed, the height will not stop growing. On the contrary, if 12-year-old women develop faster and their epiphyses close earlier, their height will only stop growing. To summarize, 12-year-old women need to strengthen their daily life management after menstruation, actively exercise and ensure a balanced intake of various nutrients.
