Endocrine System Function
Produce hormones and secrete them directly into the bloodstream
Insulin
Regulator of metabolism and storage of ingested carbohydrates, fats, and
proteins (anabolic or storage hormone).
Facilitates glucose transport across cell membranes
Counterregulatory...
Normally produced by pancreatic alpha cells when blood sugar is low to
raise blood glucose levels. In diabetes II, glucagon is still produced, but
because there is so much insulin, our pancreas doesn't respond normally.

Diabetes Mellitus
A chronic, multi-system disease related to abnormal insulin production,
impaired insulin utilization, or both. There is no cure, but diabetic
complications can be delayed or prevented with good management.
African Americans, Hispanic/Latino Americans, and Native Americans have
a higher incidence of diabetes.
Diabetes Complications
Diabetes is the leading cause of adult blindness, end -stage renal failure,
and non-traumatic lower limb amputations. It is also a major contributing
factor to heart disease and stroke.
Gerontologic Considerations with Diabetes
Diabetes prevalence increases with age related to reduced B -cell function,
decreased insulin sensitivity (!!), and altered carb metabolism.
Undiagnosed and untreated diabetes is more common in older adults,
partly due to the normal physiologic changes of aging resembling that of
DM.
Diabetes is present in at least 25% of people over age 65.
Diabetes Type I Epidemiology
Formerly known as "juvenile onset" or "insulin dependent" diabetes.

Most often occurs in people under 40 years old, and accounts for 5-10% of all people with
diabetes.
Has a sudden onset.
It is an autoimmune disease, in which B-cells responsible for insulin production are destroyed. A
genetic predisposition and exposure to a virus are factors that may contribute to the
development of DM I. Autoantibody are produced and destroy B-cells. Manifestations occur
after the pancreas is unable to produced insulin, and symptoms are rapid. Usually patients
present to ER with DKA.
Diabetes Type I Classic Symptoms
Polyuria
Polydipsia
Polyphagia
Weight loss
Prediabetes
Known as impaired glucose tolerance (IGT) or impaired fasting glucose
(IFG).

IGT: 2 hour plasma glucose 140-199 mg/dl
A1C: in the range of 5.7-6.4%
A1C Lab
It is a test that determines how well your glucose was stabilized within the
last three months.
If you have a high A1C, that means you have had high glucose levels in the last 3 months
Diabetes Type II Etiology
Probably has a genetic basis.
A genetic mutation leading to insulin resistance, and as the disease progresses, less insulin
production. There is also an increased risk for obesity.
Obesity is the most powerful risk factor, especially obesity with an increased waist
circumference.
Type II DM is now being seen in children due to epidemic of childhood obesity.
Type II accounts for 90% of diabetics.
Pancreas continues to produce insulin, but the body can't use the insulin.
Diabetes Type II Risk Factors
Obesity
