 | | In medicine, a coma (from the Greek koma, meaning deep sleep) is a profound state of unconsciousness, which may result from a variety of conditions including intoxication (drug, alcohol or toxins), metabolic abnormalities (hypoglycemia, hyperglycemia, ketoacidosis, etc.), central nervous system diseases, stroke, head trauma, seizures, and hypoxia. |
 | | A temporary coma is sometimes deliberately induced (using drugs) to reduce swelling of the brain after injury. |
