What causes insulin resistance in pregnancy?

During pregnancy, an organ called the placenta gives a growing baby nutrients and oxygen. The placenta also makes hormones. In late pregnancy, the hormones estrogen, cortisol, and human placental lactogen can block insulin. When insulin is blocked, it’s called insulin resistance.

What increases insulin resistance during pregnancy?

It has been reported that mothers carrying a female fetus have higher levels of placental lactogen and estrogen [15, 16], which promote insulin resistance [17,18,19]. Another study [20] reported that maternal leptin levels were higher in women carrying a female fetus.

But if your body can’t make enough insulin or stops using insulin as it should, your blood sugar levels rise, and you get gestational diabetes.

What week does gestational diabetes peak?

As pregnancy progresses, the levels of a host of hormones such as cortisol and oestrogen increase and this leads to insulin resistance. The peak effect of these hormones is seen in the 26th to the 33rd week of gestation.
