Embarking on the journey of motherhood means that you have to constantly think of yourself as well as your baby. And boosting your own immunity during pregnancy is one crucial aspect of it.

During pregnancy, a woman’s body begins to undergo numerous changes as it prepares to nurture the foetus.

A woman’s immune system changes during pregnancy and is considered to be in a state of uniqueness. The changes that occur follow a particular pattern. Due to these changes, many people think that women have a weakened immune system during pregnancy. However, this is not true. Contrary to common belief, a woman’s immunity during pregnancy is not weakened, but rather strengthened.

The immune system plays the most important role when it comes to protecting the mother and the baby against various ailments. The immune cells are present at the site of implantation, in order to ensure that the pregnancy lasts. It is the most important system which works to protect the foetus and the mother from damage and environmental harm.

During pregnancy, the mother’s nutritional requirement also increases. This is because the food consumed should be enough for the appropriate development of the foetus and should allow the mother to achieve a healthy pregnancy weight. Therefore, it is important for an expecting mother to follow a healthy and balanced diet. Nutritional intake can have a major impact on the immune system.
