Trans 101: Identity, Health Care, and How to Be a Decent Person About It

Strip away the sensational headlines and reality-TV caricatures, and the core fact is plain: everyone has a sex recorded at birth, and for some people, their steady inner sense of who they are does not match that record. Those people are transgender. People whose identity matches the record are cisgender. Neither is a choice or a rebellion — it is simply a variation that has always existed in human populations.

This article covers three things: what medicine actually says, what “transition” can involve, and how to treat the trans people in your life with basic decency.

Start with the conclusion: not a mental illness

In ICD-11 — adopted by the World Health Organization in 2019 and in effect since 2022 — “gender incongruence” was moved out of the mental disorders chapter and into a chapter on conditions related to sexual health. The entry was kept at all for one practical reason: keeping a door open to health care. Hormone therapy and surgery need a diagnostic code to exist inside medical systems.

An analogy: it is a bit like striking “left-handedness” off a list of problems. Writing with your left hand needs no correction — but a left-handed person may still need scissors that fit. The entry stays to hand over the scissors, not to treat a disease.

What may genuinely call for medical support is gender dysphoria — the persistent distress some (not all) trans people experience when their identity clashes with their body or social circumstances. The direction of modern medical consensus is to relieve that distress through support and affirmation, not by pressuring someone to “change back.” The latter approach is a documented harm, not a treatment (see our piece on conversion practices).

Transition is a menu, not an assembly line

Many people assume trans = surgery. In fact “transition” is an umbrella over several independent paths:

Social transition: a new name, new pronouns, different clothes and hair, telling the people who matter. For many trans people this step alone brings the most immediate relief.

Legal transition: changing the gender marker on official documents. In mainland China this is currently tied to having undergone gender-affirming surgery, which puts it out of reach for many — a piece of context worth knowing when reading about trans life in China.

Medical transition: gender-affirming hormone therapy under medical supervision, and for some, surgery. The strongest theme of WPATH’s Standards of Care Version 8 (2022) is individualization: some people only transition socially, some take hormones and never want surgery, some pursue everything. There is no “complete” or “incomplete” way to be trans.

One safety note that matters everywhere, and especially where trans-competent clinics are scarce: hormone therapy needs medical assessment and regular follow-up. Buying medication online and self-managing doses is genuinely risky. Finding care can be hard — but professional care is worth seeking out over going it alone.

How to be respectful: one principle, a few habits

The good news: this requires no specialist knowledge. The core is a single principle — treat the person as who they tell you they are.

Use the right name and pronouns. This is the same courtesy as not calling a colleague by the wrong name. Unsure? Just ask: “What would you like me to call you?” The question itself signals goodwill.

If you slip up: apologize briefly, correct yourself, move on. A lengthy display of guilt just forces the other person to comfort you.

Do not ask about private matters. “Have you had the surgery?” “What does your body look like?” “What was your old name?” — these are questions about someone’s body and medical history. You would not ask a new coworker any of them. Curiosity is not a permission slip.

Never out someone. Being told someone is trans is a gift of trust, not a license to share. In settings where you are unsure who knows, simply follow the name and pronouns the person is currently using there.

Small backup counts. Casually using the correct pronoun after someone else gets it wrong, or checking that a trans friend is comfortable at a gathering — these small moves carry more weight than you might think.

The usual misconceptions, debunked elsewhere

“Trans is just extreme gay” — no; identity and orientation are different axes. “Trans people are mentally ill” — medical classifications have said otherwise. “Trans people in bathrooms are dangerous” — neither evidence nor common sense supports this.

If you are exploring your own gender, start with gender basics or try the gender explorer — not a diagnosis, more a mirror to help you sort your thoughts. There is no deadline on figuring yourself out, and you owe no one an explanation. If things feel heavy right now, here are places you can turn to.
