4.1 Management of Chronic Endocrine Disorder Flashcards
1
Q
Diabetes
A
- Metabolic disease
- Increased glucose in body (hyperglycemia)
- Results from defects in insulin secretion, insulin action or both
- Leading cause of microvascular problems and major contributor to microvascular problems
- Major clinical Manifestation is Hyperglycemia
2
Q
Glucose
A
- Simple sugar that is an energy source for living organisms. Major component of carbohydrates
- Carbohydrates are broken down into glucose in the small intestines
3
Q
Insulin
A
- Secreted by beta cells in the pancreas
- Promotes glucose transport and opens receptors and insulin dependent tissues
- Acts as a key to transfer glucose into cells
- Brain liver and blood cells do not require insulin for glucose transport.
4
Q
Counter Regulatory Hormones of Insulin
A
- Glucagon, Epinephrine, Growth Hormone, Cortisol
- Oppose effects of Insulin
- These increase glucose levels
- Regulation of Insulin secretion is through glucose and other hormones. It is often inhibited by stress.
5
Q
Type 1 Diabetes
A
- Body does not make insulin
- Immune system attacks and destroys cells in pancreas that make insulin
- Insulin dependent
- 5% of all diabetes cases
- Onset under age 40 with about half under age 20
- Rapid onset of ketoacidosis
- Sudden Weight Loss, Dehydration, Hypoglycemia while patient is on insulin therapy
6
Q
Type 2 Diabetes
A
- Onset usually over age 40 (Gradual Onset)
- 95% of diabetes cases
- Body does not produce enough insulin
- Caused by insulin resistance. In these cases it takes more insulin to work
- Higher risk in minorities
- Obesity is the biggest risk
- Risk Factor is Metabolic Syndrome
(Abdominal Obesity, Elevated Lipids, Hypertension, Impaired Fasting Glucose)
7
Q
Risk Factors for Diabetes
A
- Age 45+
- Family history
- Overweight
- Physically Inactive
- ## High blood pressure
8
Q
Insulin Resistance
A
- Fat cells become resistant to insulin.
- When fat cells get too big it changes the insulin shape preventing the cell from absorbing glucose
- This causes pancreatic insulin production to fail due to creating more insulin to try and absorb glucose
- Losing weight reduces size of fat cells causing insulin resistance to reverse
9
Q
What can Diabetes Cause
A
- Heart disease (Hypertension, Coronary Artery Disease)
- Stroke (Brain issues)
- Kidney Disease (Nephropathy/Failure)
- Eye Issues (Cataracts, Glaucoma, Blindness)
- Dental Disease
- Nerve Damage
- Foot Problems
- Peripheral Vascular Disease (Poor healing of wounds and gangrene)
- GI/GU and Sexual Issues
- Angiopathy (damage of blood vessels or lymphatics)
10
Q
Managing Diabetes
A
- Manage blood glucose, blood pressure, cholesterol.
(ABC’s to manage diabetes) - A1C Test shows average blood glucose in last 3 days
- Blood pressure goal is 140/90
- Control Cholesterol
- Stop smoking
11
Q
Blood Levels for Diabetes
A
- Non-fasting glucose levels - Greater than 200
- Fasting glucose greater than or equal to 126 mg/dL
- Two hour post load glucose equal to 200 mg/dL
- Normal Glucose levels is 70-100
12
Q
Glyco-hemoglobin test (A1C)
A
- Measures average blood glucose levels for the past 3 months. (5.7% is normal. Or from 4% - 6%)
- A1C greater than or equal to 6.5% (Diabetes)
- A1C between 5.7% and 6.4% is pre-diabetes
- Normal A1c is less than 5.7%
- Target for people with diabetes is 7%
13
Q
A1C Test
A
Average blood glucose levels in past 2-3 months
- Measures percentage of hemoglobin that is coated with sugar glycated
- A1C greater than or equal to 6.5% (Diabetes)
- A1C between 5.7% and 6.4% is pre-diabetes
- Normal A1c is less than 5.7%
14
Q
Hypoglycemia
A
- If glucose falls to less than 70
- Less than 40 is severe which can mean too much insulin, too little food, or too much exercise
Symptoms - Shaky, Sweaty, Confused, Pale
Treatment - 15 g’s of Carbs x3
- Glucagon 1mg subcutaneous OR Dextrose 50% IV if unconscious
15
Q
Diabetic Ketoacidosis
A
- Insulin deficiency and fat breaks down into ketones (acids)
- Accumulation leads to metabolic acidosis and hyperkalemia
- Blood glucose > 250
- Usually with Type 1 Diabetes
