RISK FACTORS FOR HYPOGLYCEMIA
Sudden reduction of steroid doseAltered ability of patient to report symptomsVomiting
CAUSES:Too little food, too much insulin or diabetes medicine, or extra exercise.ONSET:Sudden, may progress to insulin shock.BLOOD SUGAR:Below 70 mg/dL. Normal range: 70-115 mg/dLWHAT CAN YOU DO?Drink a cup of orange juice or milk or eat several hard candiesTest Blood sugarWithin 30 minutes after symptoms go away, eat a snack e.g. sandwich, and a glass of milkContact doctor if symptoms dont stopadrenergicsymptoms

ETIOLOGYCauses of hypoglycemia can be classified into three groups:
1. Medications or toxins.
2. Disorders associated with fasting hypoglycemia.
3.Disorders associated postprandial hypoglycemia. TREATMENT OF HYPOGLYCEMIA
An initial bolus, 20-50 ml 50% dextrose, should be given immediately, followed by infusion of D5W to maintain blood sugar above 100 mg/dL.

ANTEPARTUM FETAL EVALUATION
Ultrasound is a valuable tool in evaluating fetal growth, estimating fetal weight, and detecting hydramnios and malformations. 1..
ultrasound antepartum fetal 2..While the false-negative rate with maternal monitoring of fetal activity is low (~1 percent), the false-positive rate may be as high as 60 percent. Maternal hypoglycemia, while generally believed to be associated with decreased fetal movement, may actually stimulate fetal activity.
3..The nonstress test (NST(Done weekly at 28 weeks and Twice weekly at 34 weeks remains the preferred method to assess antepartum fetal well-being in the patient with diabetes mellitusIf the NST is nonreactive, a biophysical profile (BPP) or contraction stress test is then performed .
