DM Flashcards
(36 cards)
Overall goal
Decrease risk factors and reduce cardiac risk
Target
A1c, lipids and BP
Biggest DM problems
Kidney failure, limb amputation, blindness
DMII mechanics
Insulin insufficiency - 50 % beta cells have failed by time of dx
Also insulin resistance and abnormal gloconeogenesis
DMII risk populations
First degree relative
AA, Latino, NA , Asian , PI
Gestational DM or delivery of baby > 9
HTN , HDL < 35
Tri >250
PCOS
DM II assessment findings
Polydipsia, polyuria, polyphagia
Weight loss
Blurred vision
Yeas or bacterial infections
Acanthosis nirvanas
Screenings DMII
Every three years if
>25 BMI
With 1 risk factor or >45 yrs old
Earlier and or yearly if
1st degree relative
High risk population
HTN, HDL, POCS, pre dm, vascular dx
Pre-DM numbers
Aic = 5.7-6.4
Fasting 100-125
OGTT - 140-199
DM numbers
Aic > 6.5
Fasting >126 ( no intake for 8 hours)
Random blood glucose >200
OGTT > 200
Normal numbers
Fasting 70-100
Peak post prandial <180
A1c < 6
Goal numbers for non pregnant adult DM
BP 140/80 LDL <100 A1c < 7 (With increased risk) <6.5 if new onset < 8 if limited life expectancy Pre prandial 70-130 Post prandial <180
Pre DM tx
Lifestyle
- weight loss 7 %
- exercise 150 min a week
- reduce calorie and fat and increased fiber
- refer to DM education
- consider metformin
DM TX
dietary medication, weight loss and exercise
Nutrition = .25 -2.9 % in 3-6 m A1c
- low carb and meiterrranean
HTN
- < 120 for aggressive
- < 140 for standard
Immunization - hard to heal
DM and HTN
Check albuminura
- if so - start with an ACE or ARB - may help renal protection
DM evaluation
A1c every 3 months until controlled then 6 months
Lipids, micoalbumin - annually
Electrolytes, liver function, and TSH - annually
BP, height, weight, feet, blood sugar - every visit
Metformin
#1 treatment Decreases production of glucose in the liver which helps with a decrease in peripheral insulin resistance
Helps with weight loss , no hypoglycemia
Improves macrosvasular outcomes
Monitor : vit b 12, lipids, LFT, creat
Risks: diarrhea, and flatulence
Dose: 500 mg QD or BID - 2000mg ( higher doses do not show improvement )
Contra - creat level above 1.4 , if getting contrast dye hold day of procedure and 48 hours after , dont give to people over 80, or people who are dehydrated
Sulfonylureas
Long acting
Simulates the beta cells of the pancreases to secrete more insulin, pt must have beta cell production
Glipizide
- shorter acting than others
- 2.5 mg before breakfast
- improved micro vascular benefits
Side effects
- weight gain, elderly sensitive
- hypoglycemia
Thiazolidineodiones TZD
15-45 mg max
Actos - pioglitazone
Enhances insulin sensitivity ( decreases peripheral tissue resistance ) and reduces gluconegenesis
Vascular benefits , beta cell preservation, approved as monotherapy
Risks: DONT give with III or IV heart disease or CHF sympotmatic Causes water retention and edema Check LFT’s Expensive, may cause bone fractures Slow onset ( 12 weeks )
Meglitinide
Prandin - repaglinide
Stimulates pancreatic secretion of insulin good for patients with post prandial hypergylcemia
Concern with hypoglycemia - rapid acting short half life < 1 hr - take before meals or up tp 30 min after - hold if skipping meals Can’t be used with sulfareas
Alpha glucosidase inhibitors
Glyset precose ( miglitol, acarbose)
Delaying absorption of carbs
Start 50 mg TID no more than 100 TID
Take with first bite of meal
Side effect
- diarrhea and flatuence
Starting insulin - general recs
Start if A1C and glucose levels are above goal despite optimal use of other dm medications
If Aic is very high >10
Self monitoring blood glucose
Important for pt teaching
Goals
- fasting and pre meal < 130
- post prandial <180
If on oral meds, check 1-2 times a day
If on insulin check fasting and pre meal
Long acting basal insulin
Lantus ( glargine ), levimer ( determir)
Onset : 1-3 hours , no PEAK, duration 24 hours
TX: stop every but metformin
- basal insulin .2 u/ kg at bedtime or 10 units - 20 units if weight over 80 kg - Lower to 1 u/kg if frail
Titration :
Increase by 1 unit every until average blood sugar is < 130 , hold if they develop hypoglycemia
- pt should check post meal glucose and evaluate 1-2 months
Meal time insulin
Rapid acting at meals (.1u/kg)
Pt have to check blood sugar 3-4 times a day
If A1c > 7 after 2-3 months of basal insulin or if pre lunch , dinner or bedtime BG are above goal (80-130) despite fasting at goal then should consider meal time insulin
Short acting insulin
Basal blous regimen = 1 long acting injection and 3 short acting injections
Decrease in endogenous insulin, most physiologic regimen, and best control
Humalog, novolog,
Onset : 10-15 min
Peak 1-2 hours
Duration : 3-5 hours
