One theory behind delayed copious milk production is that progesterone stored in adipose tissue has led to elevated progesterone levels among obese or overweight women. [20] This interferes with progesterone withdrawal upon the delivery of the placenta and consequently disrupts the activation mechanism of lactogenesis II.
High levels of progesterone, which are associated with pregnancy, inhibits prolactin and therefore lactation. [30] Prolactin increases during the initial stages of lactation and can be stimulated by estrogen but not progesterone. [30] Research, however, focuses on the role of prolactin for breastfeeding and less on other behaviors. [30]
The caloric requirement for a non-breastfeeding, non-pregnant woman changes from 1,800-2,000 kcal/day to 2,300 to 2500 kcal/day for the breastfeeding woman. Nutritional supplementation is often prescribed and recommended. In some instances women are encouraged to continue to take pre-natal vitamins. Increasing the intake of fluids is discussed.
After the luteal-placental shift, progesterone levels start to rise further and may reach 100 to 200 ng/mL at term. Whether a decrease in progesterone levels is critical for the initiation of labor has been argued and may be species-specific. After delivery of the placenta and during lactation, progesterone levels are very low. [citation needed]
The continuing of breastfeeding, while introducing solids after 6 months, to 12 months were shown to have an efficiency rate of 92.6 – 96.3 percent in pregnancy prevention. [13] Because of this some women find that breastfeeding interferes with fertility even after ovulation has resumed. The Seven Standards: Phase 1 of Ecological Breastfeeding
Elevated levels of progesterone and estrogen mediate most of the functional changes of the GI system during pregnancy. Progesterone causes smooth muscle relaxation which slows down GI motility and decreases lower esophageal sphincter (LES) tone. The resulting increase in intragastric pressure combined with lower LES tone leads to the ...
