The patients who showed any glucose intolerance before
conception or were diagnosed with overt diabetes in pregnancy (fasting glucose 126 mg/dL, 2-h glucose 200 mg/dL
or HbA1c 6.5% [48 mmol/mol]) were excluded from this
study.
We also studied the maternal characteristics and perinatal
outcomes of the patients retrospectively by medical records
(Table 1). The body weight of each monthly visit was found in
31 out of 41 patients diagnosed with GDM during early
gestation and these data were used to study the weight gain in
each pregnant trimester
