There are numerous causes of unconsciousness and most of them are associated in some way with an underlying medical condition that usually causes other problems as well.

Causes of Unconsciousness

Among the most common causes of unconsciousness are various types of head injuries such as cerebral compression, concussion or skull fracture. Cerebral compression is a condition in which an increased amount of pressure inside the skull causes a disruption of brain’s functions. It usually gets caused by blood clotting which results from significant blows to the head. The condition can be easily recognized by irregular breathing, weakness, flushed face and an altered conscious state.

The patient must seek immediate medical attention. Concussion is a brain injury characterized by dizziness, vomiting, headache, temporary memory loss and a lack of coordination. A person who suffered a concussion needs to seek immediate medical attention. Skull fracture is a condition in which a person suffers a break in the continuity of the skull bone.

The condition can be characterized by black eyes, altered conscious state, unequal pupils and lacerations and the patients that have suffered a skull fracture also need immediate medical attention. Diabetes is a condition in which the pancreas cannot produce any insulin and it can also be the cause of unconsciousness in certain cases.

The patient may experience confusion, dizziness, faster breathing, an altered conscious state and drowsiness. He/she needs to ingest sugar immediately and if the condition gets worse than medical attention is required.

Another condition that may be the cause of unconsciousness is stroke. A person experiences a narrowed, blocked or ruptured artery which takes blood to the brain so the cerebral functions become affected. Stroke can be caused by head injury, blood clots, high blood pressure or a tumor.

The condition can be instantly recognized by abnormal behavior, slurred speech, disturbed vision, dizziness, confusion, and headaches. Unconscious patients need to be transported to the hospital immediately, while those who remain conscious need to be positioned comfortably and closely monitored until the ambulance arrives. Seizure is a condition characterized by disrupted electrical activity in the brain and it can be triggered by poisoning, fever, different diseases, injuries and infections.

A person can experience strange sensations prior to a seizure. Once the seizure occurs it should not be stopped and the person who has experienced it requires immediate medical attention. Fainting is a condition characterized by a loss of consciousness caused by reduction of the blood flow to the brain due to pain, emotional shock, lack of food or other disturbances.

Medical attention must be sought in order to determine the cause of fainting.
