Diabetes Mellitus Flashcards
(33 cards)
What is the most common cause of Diabetes
Obesity
How many people have Type II diabetes
25.8 million
What is the function of Insulin?
Stimulates storage of glucose in the liver and muscle as Glycogen
Insulin brings glucose into the cell from the blood
Low basal rate of insulin if everything is functioning normally
What is the function of Glucagon?
Inverse relationship with glucose= Glucose goes up-Glucagon goes down
What is the percentage of Type II diabetes compared with other cases of diabetes
90-95%
Gestational Diabetes puts you at higher risk for developing Type II Diabetes later
How did Diabetes Type II develop originally
Typically occured over age 30 and obese
Childhood obesity is increasing likelihood of early onset diabetes
First priority is diet and exercise
Hypoglycemic agents can be used to treat initially, but conversion to insulin is usually necessary
Pancreas secretes Insulin but the body has become resistant
Pathogensis of Type II diabetes
Secretes insulin but isn’t enough or body is resitant to insulin
Muscle not absorbing glucose due to decreased stimulation from insulin
Risk factors for Type II diabetes
Diabetes in parents or siblings
Overweight- BMI greather than or equal to 25
Asian Americans-BMI>23
History of gestational diabetes
Polycystic ovary syndrome-difficult to get pregnant-take metformin even without elevated glucose
Metabolic Syndrome-Abdominal fat, HTN, Hypercholesterolemia, Hyperlipidemia
Clinical Manifestations of Type II diabetes
Have it for years-most diagnoses are accidental
Feet might feel numb, slow wound healing, eye exams are common places for accidental diagnosis
Hyperglycemia usually isn’t as big of a deal at it is in Type I
Polydipsia (increased thirst), Polyuria (increased urination), not usually Polyphagia
FEET NUMBNESS BIG
FOOTCARE TEACHING
History and physical exam info that is important to record
How much exercise patient performs
Eating habits-a lot of times they will not tell the truth
Family History of Diabetes
Episodes of Hypoglycemia/Hyperglycemia-S+S’s
Family history of Vascular problems, HTN, CVA, Renal failure
Dependant Edema-Edema that occurs when sitting up and legs hand and swell
Feet-Pulses, Sensations, and reflexes
Diagnostic tools for Diabetes
Symptoms of Hyperglycemia+Plasma glucose over 200
HBG A1C>6.5% -gives blood sugar over 120 day period
Fasting glucose over 126 is considered diabetic
Oral glucose tolerance test- 2hr test, if glucose level higher than 200 after 2 hrs diabetic
Levels of Fasting Plasma glucose
Normal=<100
Impaired= greater than 100 and less than 126
Diabetes diagnosis= greater than 126
Diagnostic tools for Diabetes-Diabetes Management monitoring
HGB A1C
Microalbuminuria-test for albumin and ketones in urine, if positive they will do 24hr profile
Fasting Lipid Profile
ECG-check for heart defects-diabetes and heart disease closely related
Treatment of Diabetes
Start with Diet and exercise
What are Dietary Management Goals?
10% weight loss can decrease need for diabetic meds
Maintain BP=HTN causes stress which increases glucose
PACE FOOD INTAKE=3 small meals, 3 small snacks
Maintain pleasure with eating
Meal planning with diabetic patient
Keep diet journal Distribute calories throughout the day Carbs should make up 50-60% Fat-20-30% Protein-10-20% Fiber=at least 25g
Keys to maintaining good glycemic index
Eat whole fruits instead of juice-fiber lowers sugar index
Combine starchy foods with protein
Raw or whole foods tend to lower glycemic index
adding food with sugars may lower glycemic index if eaten with slowly absorbed foods
What are other dietary concerns for diabetics?
Alcohol consumed on an empty stomach causes hypoglycemic effect
Alcohol decreases ability to absorb glucose and produce needed insulin
EMPTY SUGAR in ALCOHOL
Read labels
Exercise in the diabetic patient
Lowers blood sugar
Can lower CV risks
May need to have something to eat before attempting strenuous exercise
Insulin administration in Type II diabetic/or non diabetic patients
Make sure Insulin is at room temp, quick needle puncture, wait till alcohol dries
May require insulin when hospitalized-decreases risk of postop infection
Rotate sites
Hypoglycemic agents
Treats Type II diabetes Stimulates insulin secretion Most are oral, some injectable Increase stomach emptying Most will be on ACE and Aspirin-325mg 4x more likely to die of CV event
Acute Complications of Diabetes
Hypoglycemia
Hyperglycemic Hyperosmolar syndrome-HHS
Comparison of DKA and HHS
Hypoglycemia
Abnormally low blood sugar (50-60) due to too much insulin, oral hypoglycemic agents, excessive physical activity, not enough food
Adrenergic symptoms-sweating, tremors, tachycardia, palpitations, nervousness, hunger
Central Nervous System- inability to concentrate, headache, confusion, memory lapses, slurred speech, drowsiness
Severe Symptoms:disorientation, seizures, loss of consciousness, death
Treatment of Hypoglycemia
Follow 15/15 rule-15g of rapid-acting sugar(half cup of juice, 3 glucose tabs, 8 oz. skim milk)/test blood glucose in 15 mins repeat if too low
Administer 50ml of D5 solution if not responding well
Glucagon SC, IM, IV
Not typically hospitalized, if hospitalized its because there is no adults available to monitor them at home
