"Being transsexual, transgender, or gender non-conforming is a matter of diversity, not pathology". This statement is from The World Professional Association for Transgender Health (WPATH).
They provide clinical guidance for health professionals and challenge medical classification that has long considered gender identity disorder, a term that has largely been replaced by gender dysphoria.
Many trans people have chronic anxiety and depression, suicidal ideation, self-harm, agoraphobia, substance abuse, and feelings of low self-worth, detachment, and body dysmorphia.
Dr Stuart Lorimer is a consultant psychiatrist working in the National Health Service (NHS) Gender Identity Clinic in Charing Cross (London, UK) and GenderCare (London, UK), a private practice of clinicians specialising in gender medicine. He believes that, mostly, psychological symptoms are relieved when the core gender concerns are addressed.
