26
May begin at puberty or between 30 and 50
Hyperpiuitarism
27
Caused by:
Deficit of insulin secretion from pancreas
OR
Lack of response by cells to insulin
Diabetes Mellitus (DM)
28
- Very common, chronic disorder
- Prevalence increasing rapidly
- 9% of the population over 20 has DM II
- More prevalent in population over age 55
- More prevalent in African Americans, Hispanic -Americans and Native Americans
- It is anticipated that incidence of DM II will increase in the future
diabetes mellitus (DM)
29
Etiology of what type of diabetes?
Genetic component
Autoimmune reaction destroys pancreatic beta cells (insulin producing cells)
Results in an absolute deficit of insulin
type I diabetes
30
What type of diabetes
-Usually diagnosed in childhood
-Treatment: insulin injections or insulin pump
\*\*Long acting, intermediate acting, short acting
\*\*Must watch diet
-Hard to control in teenage years
-CANNOT CONTROL JUST WITH DIET
DM type 1
31
what type of diabetes?
- Formerly called noninsulin-dependent diabetes mellitus (NIDDM)
- Decreased effectiveness of insulin or a decrease in Beta cell production of insulin
- Milder form of diabetes
- Usually in older adults
- Increasing incidence in younger adults and children
- Thrifty gene: Pima Indians
type II Diabetes
32
What type of diabetes?
- Occurs during pregnancy
- Disappears after birth of child
- 5-10% may develop Type 2 diabetes later in life
Gestational diabetes
33
Pathophysiology of what?
- Insulin deficit results in decreased transportation and use of glucose throughout the body
- Blood glucose levels rise **(hyperglycemia)**
- Excess glucose spills into the urine
- A large volume of urine to be excreted **(polyuria)**
- Dehydration occurs
- Dehydration causes thirst **(polydipsia)**
- Lack of glucose entering cells stimulates appetite **(polyphagia)**
Initial stage of diabetes
34
Progression if not diagnosed early
No glucose in cells: catabolism of fats and proteins
Excessive fatty acids and metabolites (ketones)
Body cant process ketones well
Excessive ketones in blood: ketoacidosis
pH in body fluids drops
Ketoacidosis: life threatening
Diabetic ketoacidosis
35
s/s of what?
- Weight loss
- Fatigue, lethargy
- Nausea and vomiting
-Polyuria, Polydipsia, Polyphagia
diabetes
36
tests for what?

- Glycosylated Hemoglobin test (Hgb A1C)
Diabetes Diagnostic tests
37
fyi
- Fasting blood glucose: \> 126 mg/dL on two or more occasions
- Random blood glucose: one reading \>200 mg/dL
- Impaired fasting glucose: 100-126 mg/dL

fyi
38
fyi
long term management

- Diabetic patient: \<7
wasn't sure how to put this slide
39
- Glucometer
- Helps reduce fluctuations in blood glucose
home monitoring
40
what diabetes is controlled by below?
-Regulating dietary intake
Complex carbs, protein, good fats, fiber
-Weight loss if necessary
-Increasing exercise to use more glucose
-Oral medications
Decrease insulin resistance, stimulate beta cells to produce more insulin
-Sometimes insulin injections are necessary (sub Q) insulin pumps
Long acting, intermediate acting, rapid onset
type II
41
Hypoglycemia (insulin shock)
diabetes complication- Acute
42
-Deficit of glucose in the blood
-More frequently occurs with DM I
-Sudden, often following strenuous exercise, vomiting or -missing a meal after taking insulin
-Neurons: cannot use fats or protein
-Poor concentration, slurred speech, lack of coordination, staggering
Increased pulse, pale, moist skin, anxiety, tremors
LOC, seizures and death
-Treat with concentrated carbs (candy, glucose, glucagon)
Hypoglycemia (insulin shock)
43
**_Diabetes complications - Acute_**
-Increased glucose in the blood

## Footnote
In 1990, among states participating in the Behavioral Risk Factor Surveillance System, 10 states had a prevalence of obesity less than 10% and no state had prevalence equal to or greater than 15%.
By 2000, no state had a prevalence of obesity less than 10%, 23 states had a prevalence between 20–24%, and no state had prevalence equal to or greater than 25%.
In 2010, no state had a prevalence of obesity less than 20%. Thirty-six states had a prevalence equal to or greater than 25%; 12 of these states (Alabama, Arkansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Oklahoma, South Carolina, Tennessee, Texas, and West Virginia) had a prevalence equal to or greater than 30%.
