Prediabetes and pregnancy

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Perinatal Medicine

Background:

• Prediabetes, characterized by mild glucose intolerance, affects pregnancies.
• Management of prediabetes during pregnancy requires careful consideration of fetal outcomes and maternal health.
• Previous studies have not fully elucidated the impact of unrecognized prediabetes on perinatal losses.

Purpose of the Study:

• To evaluate perinatal losses in pregnancies with mild glucose intolerance (prediabetes).
• To determine the role of obstetric factors in perinatal outcomes for prediabetic pregnancies.
• To assess the efficacy and safety of hypoglycemic agents in pregnant women with prediabetes.

Main Methods:

• A prospective study followed 105 pregnancies in women with mild glucose intolerance.
• Hypoglycemic agents were withheld unless frank diabetes was diagnosed.
• All deliveries were attended by medical residents.

Main Results:

• Only two perinatal losses (1.5%) occurred, with one potentially avoidable.
• Perinatal losses in prediabetic pregnancies were primarily linked to associated obstetric factors.
• Uncomplicated prediabetes did not show a higher perinatal loss rate compared to non-diabetic pregnancies.

Conclusions:

• Early recognition of prediabetes enables timely management of potential complications.
• Hypoglycemic agents do not improve immediate fetal salvage in prediabetic pregnancies without frank diabetes.
• The use of hypoglycemic agents in pregnant prediabetics is not recommended due to potential teratogenic risks.
