Guidelines for the Calculation of Initial Insulin Dose in Gestational Diabetes
 

Weeks of Gestation Total Daily Insulin
Week 1-17 0.7  to 0.8  U/kg  actual body weight
Weeks 18-24 0.8  to 1     U/kg  actual body weight
Weeks 25-32 0.9  to 1.2  U/kg  actual body weight
Weeks 33-38 1.2  to 2     U/kg  actual body weight

Weight (current) in pounds?       Insulin dose? units/kg/day 

Calculated Initial Insulin Regimen

AM Reg      AM NPH PM Reg     PM  NPH
NPH may be given separately at hour of sleep to avoid early morning hypoglycemia.

Stress, sepsis, steroids, obesity and advancing pregnancy increase

estimated energy requirement

 

14–18 years of Age
EER = 135.3 − (30.8 × age [y]) + PA × [(10.0 × weight [kg]) + (934 × height [m])] + 25

19 Years and Older
EER = 354 − (6.91 × age [y]) + PA × [(9.36 × weight [kg]) + (726 v height [m])]
