W.S. is a 25-year-old woman referred for newly diagnosed gestational
diabetes mellitus (GDM) after having a 1-hour plasma glucose (PG) of 150 mg/dl
during a 50-g glucose challenge test at 28 weeks' gestation. She denied any
history of polyuria, polydipsia, polyphagia, or visual disturbances. During
this pregnancy, she had gained only 5 lb by 31 weeks and denied any
complications. Before the pregnancy, her baseline weight was 205 lb, and her
BMI 33 kg/m2. Overall, she was feeling well and tolerating her
pregnancy well.
Her medical history was significant for a single pregnancy 4 years ago that
was not complicated by GDM. She delivered a healthy, full-term girl weighing 7
lb, 4 oz, by an uncomplicated spontaneous vaginal delivery (SVD). She denied
any subsequent history of impaired fasting glucose (IFG) or impaired glucose
tolerance (IGT). She denied a family history of type 2 diabetes. However, her
4-year-old daughter had been diagnosed with type 1 diabetes. She denied any
tobacco or alcohol use.
After being diagnosed with GDM, she received appropriate dietary counseling
and was instructed in home blood glucose monitoring. Secondary to persistent
fasting hyperglycemia, she was started on human insulin NPH, 5 units
subcutaneously daily at bedtime. She continued to monitor fasting and 2-hour
postprandial blood glucose values. Her GDM was followed closely, and her NPH
insulin was titrated to 14 units at bedtime.
Because of ongoing postprandial hyperglycemia, insulin lispro was added for
prandial coverage, in a dose of 1 unit/20 g of carbohydrate consumed. Her
blood glucose control improved on intensive insulin therapy. Her hemoglobin
A1c (A1C) was excellent at 5.5%. At term, she delivered a healthy
boy of 8 lb, 8 oz, by uncomplicated SVD.
The patient was scheduled for a postpartum follow-up, including a 75-g oral
glucose tolerance test (OGTT). She denied any symptoms . . . [Full Text of this Article]
