A coma is a serious medical emergency, which, according to Medical News Today, requires immediate action to save the patient and retain brain function. Doctors will then try to determine the cause of the coma through blood tests and imaging scans.
Common causes of coma include: traffic accidents, acts of violence that result in a traumatic brain injury, blood sugar levels fluctuating too high or low in diabetic patients and exposure to toxins such as carbon monoxide and lead. Drowning victims sometimes experience coma due to lack of oxygen to the brain. Encephalitis and meningitis can also cause coma from swelling of the tissues around the brain and brainstem.
