How to Say "to faint" in Spanish
The most common Spanish word for “to faint” is “desmayar” — use 'desmayar' for a general loss of consciousness, often due to emotional shock, heat, or sudden illness..
desmayar
/des-ma-YAR//desmaˈʝaɾ/

Examples
Ella se desmayó al ver la sangre.
She fainted when she saw the blood.
Tengo tanto hambre que siento que me voy a desmayar.
I'm so hungry that I feel like I'm going to pass out.
El calor era tan intenso que varios soldados desmayaron.
The heat was so intense that several soldiers fainted.
Using the 'Se'
When you want to say a specific person fainted, you almost always use the reflexive form 'desmayarse' (adding me, te, se, nos, os). For example: 'Me desmayé' (I fainted).
Active vs. Passive Fainting
Without the 'se', desmayar is often used in literature to describe the act of losing strength or spirit generally, rather than a person physically falling down.
The 'Se' Confusion
Mistake: “Yo desmayé ayer.”
Correction: Yo me desmayé ayer. (In everyday Spanish, you need the reflexive 'me' to show it happened to you.)
desplomar
/des-plo-MAR//desploˈmaɾ/

Examples

People and 'Se'
When people are the ones falling or fainting, always use the 'se' form: 'Juan se desplomó.'
Mistaking with 'desplumar'
Mistake: “El edificio se desplumó.”
Correction: El edificio se desplomó. 'Desplumar' means to pluck feathers from a bird!
desvanecer

Examples
Ella se desvaneció por el intenso calor.
She fainted because of the intense heat.
Al ver la sangre, el hombre se desvaneció.
