The immune system of women during pregnancy becomes weaker, which makes them more susceptible to colds and the flu.

The immune system, in addition, may result in the development of new allergies during pregnancy.

Women’s immune systems weaken to the point that they can have a fetus with half the mother’s genes.

The immune system contains two subsystems: innate and adaptive immunity. Both have different responses to pregnancy and require a decrease in responses to the adaptive part of the immune system to reach this point.

The immune system has two leading roles during pregnancy: first, protecting women from bacterial and viral infections, and second, promoting the healthy development of the fetus.

Changing the state of the immune system occurs when hormones fluctuate because hormones modify the immune system.

Experts believe that hormones during pregnancy are responsible for the relationship between immunity and allergies.
