A loss of consciousness occurs when not enough blood reaches the brain and corresponds to a loss of awareness of oneself and one’s surroundings. In most cases it is due to a particular situation; upon receiving bad news, extreme pain, fear of needles, etc. If a patient with a heart or neurological disease, or who takes certain medicines, loses consciousness, call emergency services immediately.
