性别焦虑这个词描述了一种强烈的感觉，即一个人的实际性别与出生时分配给他们的生物性别不同。 出生时具有男性生殖器和身体特征的性别不安的人可能强烈地感觉到他们实际上是女性，而那些出生时具有女性生殖器和身体特征的人可能强烈地感觉到他们实际上是男性。 心悸被定义为一种充满不安或不满的深刻状态。 性别焦虑症以前被称为“性别认同障碍”。然而，这表明性别混乱是精神疾病，事实并非如此。 2013年，美国精神病学协会（APA）的“精神疾病诊断和统计手册”承认，只有在实际影响个人健康或幸福的情况下，性别混乱才会成为医疗条件，并将其重命名为性别不安。 重要的是要明白，虽然性别不安是一种公认的医疗状况，但它不是精神疾病。
The term gender dysphoria describes a strong feeling that one’s actual gender is different from the biological sex assigned to them at birth. Gender dysphoric persons born with male genitalia and physical characteristics may strongly feel they are actually females, while those born with female genitalia and physical characteristics may strongly feel they are actually males. Dysphoria is defined as a profound state of unease or dissatisfaction. Gender dysphoria was formerly called “gender identity disorder.” However, this suggested that gender confusion was a mental illness, which it is not. In 2013, the “Diagnostic and Statistical Manual of Mental Disorders” of the American Psychiatric Association (APA), acknowledged that gender confusion becomes a medical condition only if actually affects one’s health or well-being and renamed it gender dysphoria. It is important to understand that while gender dysphoria is a recognized medical condition, it is not a mental illness.
