Blood sugar : In people with diabetes, coma can occur when blood sugar levels stay very high. That's a condition known as hyperglycemia. Hypoglycemia, or blood sugar that's too low, can also lead to a coma. This type of coma is usually reversible once the blood sugar is corrected. Oxygen deprivation: Oxygen is essential for brain function. Cardiac arrest causes a sudden cutoff of blood flow and oxygen to the brain, called hypoxia or anoxia.
What is an induced coma? A coma can be induced through hypothermia. An induced coma gives the brain the rest necessary to recover. Medically induced coma requires an extreme type of general anesthesia that essentially deactivates the brain; this prevents the patients from being revived or reacting on their own. During an induced coma, cardiac rhythm, blood pressure and breathing are maintained mechanically or with the use of drugs.
