Being transgender is not the same as having gender dysphoria. Gender dysphoria is the (sometimes) associated distress. It is effectively an administrated diagnosis, without it many trans people would not be able to access treatments they need.
The pages goes on with:
> The diagnosis was created to help people with gender dysphoria get access to necessary health care and effective treatment. The term focuses on discomfort as the problem, rather than identity.
