Symptoms of Loss of Consciousness
Dizziness. Sensation that you are going to lose consciousness within a few moments, including instability of the body (cannot remain standing correctly).
Feeling of heat or a hot flush. At the beginning, a feeling of intense heat may be noted, particularly, in the face and neck.
Blurred vision. It is a very common symptom just before losing consciousness.
Cold sweats. It is a fairly common symptom.
Heaviness in the legs and difficulty in moving the body and even to speak.
Confusion, bewilderment. Initially, they may note that they do not know where they are, or what day, month, or time it is, and that it is difficult to think lucidly.
Nausea, and sometimes vomiting, can accompany the symptoms.
Besides losing consciousness when one faints, they may also present with:
- Pallor. The person that suffers this becomes increasingly paler as the clinical condition progresses, until they recover.
- Fall. They may fall down on the floor.
- Spasmodic shaking of the body. As if it was an epileptic fit.
- Pulse weak and slow or rapid.
- Lowering of blood pressure (arterial hypotension). The blood pressure is usually low because, during this time the body “works” to send blood to the brain
