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.
The brain wave activity in a comatose person is very different from that of a sleeping person; you can wake up a sleeping person, you can't wake a person in a coma. A coma usually does not last for more than a few weeks. Many people recover their full physical and mental functioning when they emerge from a coma.omeone in a coma cannot consciously respond to stimulation. Coma can be caused by an underlying illness, or it can result from head trauma. A comatose person is still very much alive, but he or she is not simply asleep.
