As with any surgery, labiaplasty surgery has got it’s own risks:
The sensitivity of the vulvar region may reduce
Vagina may become dry and numb
Scarring during the procedure can result in painful sex. (Typically, with an experienced gynecologist, this may not happen but there is a remote possibility).
Also, removing excess skin from the labia minora, the chances of vaginal infections may go up. Labia minora typically covers the opening of the vagina and also helps vagina manage the pH balance of the fluids inside it. If the pH balance gets disturbed, that can result in growth of unwanted bad bacteria and microbes from external environment will also be able to enter and grow inside the vagina resulting in infection and discharge.
