If the labia are large clinically it is mainly a matter of congenital development, just like the development of the human features, some people have slightly larger mouths and some will be smaller. The same goes for the labia, some people will have big lips and some people will have small lips. As long as it does not affect the normal sexual life and daily life, clinically it can be done without intervention. If some people have overdeveloped labia, it will cause discomfort in daily life due to friction between clothing and labia, or inconvenience to sexual life, or cause discomfort in the lower abdomen during menstruation when the menstrual blood does not flow smoothly. In clinical practice, plastic surgery is needed to remove the oversized labia partly, so as to achieve the purpose of making the labia smaller. It is advisable to go to the hospital 3-7 days after menstruation to have the procedure done. After the procedure, it is important to keep the vulva clean to avoid infection.
