What is another word for becoming unconscious?
Pronunciation: [bɪkˈʌmɪŋ ʌnkˈɒnʃəs] (IPA) 
When someone becomes unconscious, it means that they have lost consciousness and are not aware of their surroundings. There are several synonyms to describe this state, such as blacking out, fainting, passing out, or falling into a coma. Blacking out refers to a temporary loss of awareness, usually caused by alcohol or drugs. Fainting occurs when a person feels lightheaded and suddenly loses consciousness. Passing out is similar to fainting but often used to describe a more severe loss of consciousness. Falling into a coma is a prolonged state of unconsciousness, usually caused by a severe medical condition or injury. Whatever the cause, becoming unconscious can be a serious event and requires medical attention.
