2. Definition
• Gestational diabetes is a condition which a
woman with no history of diabetes is
diagnosed with diabetes mellitus during her
pregnancy.
• Diabetes is one of the most common
complication of pregnancy.
4. • In every pregnancy, the placenta generates
several hormones:
– Growth hormone
– Corticotropine releasing hormone
– Placental lactogen
– Progesterone
• These hormones are diabetogenic; meaning,
they can cause diabetes.

6. • In diabetic mother, the chance of a stillborn is
4 to 6 times higher than non-diabetic mother.
• This is caused by the high blood sugar level
and high insulin level in the mother’s blood
which in turn caused hypoxia (lack of oxygen)
in the baby.
7. • Macrosomia is the most common
complication of gestational diabetes,
especially because of lipid metabolism
disorder.
