causes somebody to fall unconscious?​

Answer 1

Answer:

Unconsciousness can be caused by nearly any major illness or injury. It can also be caused by substance (drug) and alcohol use. Choking on an object can result in unconsciousness as well. Brief unconsciousness (or fainting) is often a result from dehydration, low blood sugar, or temporary low blood pressures
