Goals Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Clinical Goals: Elimination of ketosis. Elimination of hyperglycemia and it’s symptoms. Prevention of chronic complications. Additional Goals: Maintaining desirable weight. Maintaining normal growth and sexual maturation. Maintaining psychosocial well-being. Achieving normal fertility and pregnancy. Sustaining normal family and sexual life. Control Goals: HbA1c <7%. Pre-meal SMBG mg/dl ( mmol/l). Bed time SMBG mg/dl ( mmol/l). No ketonuria. Mean blood glucose level mg/dl ( mmol/l).

Highlights Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Insulin: Type 1 diabetes is dependent on insulin for survival. Insulin is classified by source or duration of action. Human insulin has less allergy or lipoatrophy. More than one injection is needed and different types. Proper action During honeymoon phase. The commonest side effect is hypoglycemia. Nutrition: Enable near normal blood glucose level. Maintain a reasonable body weight. Protein 10-20%, Fat 15-25%, Carbohydrate 65%. Fibers, vitamins, and minerals. Food exchanges or carbohydrate counting. Total daily calorie intake adjustment. Exercise: Should be integrated. Weight control and improve well being. Pre-exercise medical evaluation. Monitoring: Glucometer use SMBG to monitor blood glucose level. Adjustment of insulin, diet, and exercise. Urine testing for both glucose and ketones. HbA1c the best index for control.

Blood Glucose Curve Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Glucose variations in our culture:

Insulin Use Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Regular and NPH use twice daily the commonest regimen used. Premixed with different concentration (30/70, 40/60, 50/50). Lunch is the biggest meal usually but no insulin dosing.

Hyper-glycemia window Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Hyperglycemia Window Cause: Lack of insulin Lunch effect afternoon snacks Effect: Pre-meal hyperglycemia  HbA1c by 1.7%

Hyper-glycemia window Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Treat by adding regular dose pre-lunch

Hyper-glycemia window Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Treat by adding regular dose pre-meals and small one before sleep

Hypo-glycemia window Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Hypoglycemia Window Cause: NPH evening dose ? Late sleep Effect: Somogyi effect Week end Problem

Hypo-glycemia window Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Treat by moving am dose late and regular dose pre-supper and NPH at night

Hypo-glycemia window Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Treat by moving am dose late and regular dose pre-supper and another dose pre bed

Somogyi Phenomenon Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Cause: Counter regulatory hormones response to hypoglycemia at med-night. Increase in hepatic glucose production. Insulin resistance because of the Counter regulatory hormones. Treatment: Decrease pre-supper intermediate insulin. Defer the dose to 9 PM. Change or start pre-bed snack.

Dawn Phenomenon Multiple Insulin Injection Therapy INSULININJECTIONINSULININJECTION Cause: Less insulin at bed time. More food at bed time. Not using NPH at night. Treatment: Use enough dose. Reduce bed time snack. Add NPH pre-supper.
