There is a number of reason why pregnancy is considered as a “different state.” Women often change a lot during this period, and various things from their surroundings have different effects. As stress is one of those things, it is very important that we all avoid it, especially pregnant women.

A study published recently in the Journal of Physiology revealed that stress can make a great impact on both the mother and the fetus.

The experiment conducted by this study involved injecting pregnant mice with the natural glucocorticoid corticosterone, in order to test whether stress has an impact on the offspring.

As the results showed, the increased levels of the stress hormones cause some significant changes in both the mother and the baby. Apparently, being stressed made the mother eat more, but lowered the amount of glucose transported from the placenta to the fetus.

The lead author of the study, Dr Owen Vaughan explained: “Together with previous work, the findings show that maternal glucocorticoids regulate fetal nutrition. Higher glucocorticoid hormone levels in the mother can reduce glucose transport across the placenta and lead to a decrease in fetal weight.”

The combination of nutrients the fetus receives is determined solely by the mother. This means that if the mix is wrong, the child might develop long-term metabolic health issues. So if you’re pregnant and you’re feeling stressed about something, just think happy thoughts.
