It is a normal phenomenon for girls to have menstruation. As long as the menstrual flow is normal, if coupled with attention to hygiene during menstruation to prevent infection or secondary diseases during menstruation, then normal menstruation will not affect height. Because the bleeding volume of normal menstruation is small, it will not have a relevant effect on the development of the body, unless there is a serious gynecological disease that causes a large amount of bleeding and lasts for a long time. This can cause anemia, and the lack of blood supply can lead to effects on the body’s height development. In addition the development of height is determined by hormones such as growth factors of the body, not only the oxygen supply of the blood system, but also height has a certain family nature. If the parents are taller, then the child’s basic genes are also better, under normal circumstances will not be affected. So this worry is superfluous, there is no direct inevitable connection between the two, please parents rest assured.
