During postpartum recovery, low levels of various hormones lead to which of the following effects?

During postpartum recovery, low levels of various hormones, particularly those that are elevated during pregnancy, contribute to physiological changes in the body. One significant effect of these reduced hormone levels is the lowering of glucose levels.

During pregnancy, elevated levels of hormones such as human placental lactogen (hPL) and estrogens increase insulin resistance, leading to higher glucose levels to meet the energy demands of the growing fetus. After delivery, as the hormonal influence from the placenta diminishes, insulin sensitivity typically increases and glucose utilization by tissues improves. Consequently, this can lead to lower blood glucose levels during the postpartum period.

This transition is crucial for postpartum recovery, as it helps the woman's body return to a non-pregnant state and regulates metabolism. It ensures that the body can effectively manage energy levels while simultaneously providing for any breastfeeding needs as warranted.

Other effects that may occur postpartum, such as diuresis and reduced blood pressure, while relevant, are secondary responses to hormonal changes rather than the primary impact of lowered hormone levels on glucose metabolism. Increased angiotensin II is typically related to the body's response to fluid balance and blood pressure regulation, which may not be directly correlated with low hormone levels post-delivery.
