19Hypoglycemia Prevention Strategies 2. Meal/Snack TimingMajor issue w/a.m. NPH/LenteMinor issue w/Lantus or UltralenteNot usually an issue with pump use
20Hypoglycemia Prevention Strategies 3. Proper Correction Doses1500-Rule (aggressive)1800-Rule (conservative)(Total Daily Ins.)/1500 or 1800May vary day vs. night(nighttime often 50% more than day)
21Hypoglycemia Prevention Strategies 4. Proper Meal/Bolus DosesI:C Ratio that matches pre-meal BG 3-4 hours (not 2!) after eatingI:C Ratio often varies from meal to meal(bkfst dose > lunch & dinner)
22Hypoglycemia Prevention Strategies 5. Account For “Unused” Insulin*Time sincemeal insulin 1 Hr2 Hrs3 Hrs4 HrsConservative Approach70% left40% left10% left0% leftAggressive Approach67% left33% left* Newer pumps figure this automaticallybased on the insulin duration you set.
23Hypoglycemia Prevention Strategies 5. Account For “Unused” InsulinExample:Gave 6.0 units at 7pm, BG 200 at 9pm.Conservative approach: 40% remaining (6 x .4) = 2.4 units leftAggressive approach: 33% remaining (6 x .33) = 2 units leftSubtract the unused insulin from your usual correction dose!
24Hypoglycemia Prevention Strategies 6. Carb Counting AccuracyProper Portion MeasurementLook Up Unknown / Restaurant FoodsUse Carb FactorsSubtract 100% of FiberSubtract 50% of Sugar Alcohols
25Hypoglycemia Prevention Strategies 7. Extend Meal Insulin When NecessaryUse When:Portions are very largeMeal is prolongedFood is low-glycemic index (pasta, legumes, dairy…)Apply Via:Square/Dual/Extended/Combo bolus on pumpDelayed or Split bolus on injections
26Hypoglycemia Prevention Strategies 8. Adjustment for Physical ActivityExercise, recreation, chores: all count!Reduce meal insulin (25%, 33%, 50%) for after-meal activitySnack prior to after/between meal activityLower long-acting/basal insulin prior to and during prolonged activity
27Hypoglycemia Prevention Strategies 8. Watch Out for D’OH!(Delayed Onset Hypoglycemia)Following High-Intensity ExerciseFollowing Extended Duration ActivityMay Occur Up to 24 Hours AfterAdjustments to food and insulin may be necessary
28Hypoglycemia Prevention Strategies 9. Adjustment for AlcoholAlcohol reduces the liver’s output of glucose and masks hypoglycemic symptomsDelayed BG drops can occurDecrease basal insulin (or overnight long-acting insulin) after drinking
32Hypoglycemia Prevention Strategies 11. Recording & AnalysisReview every 7-10 daysLook for patterns> 10% below target given timeLows during/post-activityLows on School/Work vs. off-dayLows Post-Menstrual
33Hypoglycemia Prevention Strategies 12. CaffeineHelps reduce risk of nighttime hypoglycemia, but not daytimeBenefit seen with 4 cups of coffee per day (250 mg caffeine twice daily)WILL YOU SLEEP???
34Hypoglycemia Treatment Mild/Moderate LowCheck BG FirstTreat w/High-Glycemic Index FoodTreat w/Proper AmountRe-Check in 15 MinutesHigh-GI FoodsGlucose TabletsDry CerealPretzelsGraham CrackersVanilla WafersJelly Beans
35Hypoglycemia Treatment Use of Glycemic IndexLower GI foods digest & convert to glucose more slowlyHigh-fiber slower than lowHi-fat slower than lowSolids slower than liquidsCold foods slower than hotType of sugar/starch affects GI
