After pregnancy the mother-to-be’s body will undergo various changes, both good and bad. There may be a variety of discomforts: some people will have insomnia, some will have a strange taste in their mouths, some will look at their obedient husbands horizontally and vertically, but in fact, as long as these discomforts do not seriously affect your work or life, there is no need to worry too much. For women, pregnancy is a big test for their health, I made up an English phrase PCT to describe this state, PCT stands for Pregnancy Challenge Test, which means pregnancy is a challenge and a big test for women’s health. If hypertension occurs during this challenge, then there is a higher chance of developing chronic hypertension in her 40s and 50s, and if she develops gestational diabetes, then she has a high chance of getting type II diabetes in her 40s and 50s, and so on. If everything is normal throughout pregnancy, then congratulations, you will have a lower probability of getting chronic diseases in the future. For women, pregnancy has quite a few additional benefits, such as improving overall body function, in addition to helping us predict future illness and health. In the former Soviet Union and Eastern Europe during the Cold War, in order to improve the performance of female athletes, coaches would deliberately arrange for them to become pregnant and then abort their babies, and then after proper recovery training, many of them would have significantly improved their athletic performance, but of course this inhumane practice is no longer done. After pregnancy, all the organs and systems of the body will undergo many beneficial changes under the action of estrogen and progesterone, somewhat like the “breaking in” process of a new car. As we all know, the condition of a new car is not in the best condition, and it needs to be “broken in” after a certain number of miles before it reaches the best condition. For women, pregnancy is a good “break-in”.
