Why is the trans suicide rate so high?
The evidence from detransitioners and long-term studies suggests the high suicide rate is driven less by social rejection or gender dysphoria itself and more by unresolved mental-health conditions and the failure of medical transition to relieve distress.

1. Transition does not lower suicide risk.
A landmark Swedish study followed sex-reassigned adults for up to 30 years and found their suicide mortality remained “strikingly high” even after adjusting for prior psychiatric problems, with risk rising sharply after 10 years. Detransitioner CoolEmployment5080 summarizes: “the largest Swedish study… found overall mortality… particularly death from suicide… was higher… than for controls of the same birth sex.” [citation:f2eb122a-7c5d-4698-afa6-d56fd6f318ab]

2. Suicidality persists despite full acceptance.
UCLA/Williams Institute data show that elevated attempt rates remain even among trans people who report “being fully accepted as trans and always having strong family and friend support.” badsalad notes this indicates “the discomfort and depression comes from a different source.” [citation:5172714d-2bea-4fd0-99ea-afdcb9de930a]

3. Co-occurring mental illness is the stronger correlate.
Multiple detransitioners emphasize that trans individuals often carry multiple psychiatric diagnoses—averaging three per person—and that the ~40 % suicide-attempt figure “stays about 40 % even after social and medical transition.” Hot_Ad_2492 concludes this points to “depression and other mental illness, not bigotry.” [citation:dcb2aa88-59e7-47ca-af0e-779f83f708da]

4. Comparison with other marginalized groups undercuts the discrimination-only narrative.
Commenters observe that gay people face criminalization or death in many countries yet do not reach comparable suicide rates, and that AFAB trans people (who generally experience less outward persecution) still show the highest attempt rates. graybutch argues this “does say something about whether or not it’s actually transphobia that’s behind it.” [citation:27bac9cf-952a-4987-9463-678eec2843d8]

In short, the data indicate that medical transition and social acceptance alone do not resolve the underlying mental-health conditions that appear to be the primary drivers of suicidality in the transgender population.
