I was reading recently about people who feel the need to have one of their limbs amputated. What is that disorder called?

The disorder is called body integrity identity disorder (BIID), where individuals feel a strong desire to physically amputate a healthy limb as a way to have greater physical integration with their preferred gender identity. BIID typically begins in early adulthood and can cause significant distress and difficulties with daily life activities, making self-amputation a viable option for some individuals.
