PregnancyHormones and a Woman’s Bodily Adaptations to Pregnancy

Psychologicalchanges during pregnancy are ordinary adaptations that occur toensure a healthy fetal development. Among the major adaptive changesthat occur in a woman’s body during pregnancy are the modificationsin their endocrine system which results in hormonal changes.Pregnancy hormones help control the many bodily adaptations happeningto a woman, thus, ensuring the well-being of an embryo or fetus. Inthis discussion, I will expound on the four major pregnancy hormonesand the major physiological adaptations that arise due to thesehormones.

Thefour most important pregnancy hormones include the Human ChorionicGonadotropin (hCG), progesterone, estrogen, and Human PlacentalLactogen (hPL). The hCG hormone is produced in the placenta and isaimed at maintaining a steady production of progesterone hormone inthe corpus luteum (Thornburg &amp Giraud, 2014). The hCG hormone isonly produced in the instance of a pregnancy and is present in urineits presence is used to determine whether a woman is pregnant or not.Secondly, the production of progesterone hormone in the placentafollows. Progesterone aids the release of an egg from the ovary andits implant on the uterine wall. Moreover, progesterone works incollaboration with hormone relaxin to ensure the relaxation of theuterine walls creating enough space to accommodate the fetus. Also,progesterone hormone helps to thicken the uterine walls before afertilized egg implants on it (Thornburg &amp Giraud, 2014).Thirdly, the placenta produces the estrogen hormone which ensures ahealthy fetal development and is also associated with female sexualcharacteristics. Lastly, the hPL hormone produced by the placentastimulates fatty acid metabolism, lipolysis, and the breast glands toproduce milk (Thornburg &amp Giraud, 2014).

Generally,the changes on a woman’s endocrine system consequently affect anindividual’s feelings and emotions. At times, one may feel happyand exited while at other times tearful and easily agitated. Duringthe first trimester, pregnant women may experience these mood swingsand lose control of their own emotions.
