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.
Hypoglycemia refers to blood sugar levels that drop below the normal range. When blood sugar becomes too low, the body releases a hormone called epinephrine, which causes the body to release stored sugar into the blood. Epinephrine produces symptoms such as hunger, sweating, and shaking. As blood sugar drops even more, the body cannot get enough sugar to the brain, and additional symptoms develop due to the decrease in sugar to the brain. This causes dizziness, confusion, and weakness. As blood sugar continues to drop, and the brain does not have enough sugar to function properly, more severe effects occur, including permanent brain damage, seizures, coma, and death.
