Circulating levels of leptin and pregnancy increase throughout gestation. It is clear that maternal metabolic alterations, such as obesity and diabetes, have negative consequences on the offspring, for either embryonic teratogenic effect or outcomes at birth, such as mortality or pre-term birth. There were higher levels of leptin in maternal obesity compared to lean pregnant women which contributed to leptin resistance [ 35 ].
