What are the differences between diabetic ketoacidosis and a hyperosmolar hyperglycemic state?

Insulin and acidosis: Hi. DKA is an insulin deficient state that contrary to lay bias, occurs in both type 1's AND type 2's. The nonketotic hyperosmolar, hyperglycemic state is a condition that occurs in type 2's; they have enough insulin to prevent ketoacidosis but not enough to prevent profound hyperglycemia and hyperosmolarity. It takes FAR LESS insulin to prevent ketoacidosis than it does to prevent hyperglycemia.
