G-LOC, or G-induced Loss Of Consciousness, occurs when an individual experiences a significant drop in blood flow to the brain due to the effects of high gravitational forces (G-forces). This is often seen in pilots, astronauts, and individuals in high-speed maneuvers where they are subjected to rapid acceleration or deceleration. When the body experiences high G-forces, blood is pulled away from the brain and can lead to a temporary loss of consciousness.
