Transgender people get diagnosed gender *dysphoria*, not dysmorphia.
Dysmorphia is an obsessive disorder where a person’s perception of reality is distorted. A dysphoria is a persistent unease with a distressing situation. You can have dysphoria from your crappy job. The treatment for a dysphoria is to change the situation. Losing weight doesn’t relieve dysmorphia for anorexic people. Transition does relieve dysphoria for trans people. We’re not delusional, we need a change of circumstance
