In the E.R. he had severe ketoacidosis and later became comatose. He died two days later, primarily from cerebral edema. I am sorry to hear about the tragic loss of your son.
Cerebral edema is the complication that every doctor looking after children with diabetes fears.
The cause is not fully understood but involves cells in the brain becoming swollen with fluid and the movement of salts and sugar in and out of these cells is disrupted. Obviously, however, you will now be very sensitive to possible symptoms of drinking or urinating a lot and you should check out any suspicions quickly. I hope that this is some reassurance to you. KJR Additional Comments by Dr. Lebinger First of all, let me express my condolences on your tragic loss. Ketoacidosis is a very serious condition which can occasionally lead to either brain damage or death.
