Transmedicalism

Transmedicalism is the view that sex-based dysphoria is a requirement for being transgender. People who hold this opinion are called transmedicalists, or "transmeds" for short. They may also be called "truscum", which is sometimes considered pejorative. Many transmeds do not believe nonbinary genders are valid, or apply rigid requirements for which ones are valid. Transmeds also commonly believe that medical transitioning is needed in order to be genuinely transgender.

Nonbinary journalist Jessie Earl sums it up:

"Transmedicalists believe that being transgender is contingent upon suffering and/or medical treatment. This ideology completely erases, and is harmful towards, nonbinary identities, as well as binary-identified transgender people who may experience what is known as gender euphoria, or joy at having their gender affirmed. Transmedicalists, who often, unfortunately, face varying levels of suffering, trauma and bigotry due to their experience with gender dysphoria, often see those within the transgender community who do not experience a similar level of suffering to have not "earned" being a part of the community."

Those who take the opposing view, that dysphoria is not required, are called (by transmeds) "tucutes" or "transtrenders".

Many official organizations, such as the USA's National Center for Transgender Equality and the American Psychiatric Association, agree that "Not all transgender people suffer from gender dysphoria".
