What is the difference between type 1 and type 2 diabetes?
Patients w/type 1 diabetes stop making insulin.These patients are generally young and slender.

In type 2 diabetes, insulin secretion is not absent & may actually be elevated, but not sufficient to overcome insulin resistance. Patients are usually obese and older than age 30.
Occurs in type 1 diabetes when glucose cannot be utilized due to lack of insulin, causing accelerated starvation that forces the body to make ketones for fuel

How do insulin and glucagon modulate body fuel stores?
Insulin - stores energy from glucose intake.
Glucagon - releases glucose to tissues bewteen meals.
What is the role of somatostatin in glucose metabolism?
Somatostatin suppresses both insulin and glucagon.
What is the effect of insulin on glucagon?
Insulin suppresses glucagon because you cannot store energy and release it at the same time.
What is the effect of glucagon on insulin?
Glucagon activates insulin to moderate glucose release, because glucose can't be wasted.
How do you treat type 2 diabetes?
Weight loss, insulin increasing drugs (sulfonylurea), exercise.
How do you treat type 1 diabetes?
Insulin injections, restrict diet, exercise.
What is one symptom in diabetics caused by excess glucose in the circulation?
Polydipsia/polyuria because of high osmolarity of the blood will increase urine output.
How will metabolic acidosis affect respiratory rate?
Increases respiratory rate. Increased ketoacidosis in the blood mimics an increase in carbonic acid as if there were an oxygen deficit. This will increase lactic acid production
