Like cravings, food aversions are a normal occurrence during pregnancy. You may find some foods so repulsive that you feel pukish to their smell or taste. It’s like developing a sudden dislike to the foods you enjoyed before. Food aversion may be annoying since they don’t let you eat properly, but it can be managed.

Read this MomJunction post to know more about food aversions during pregnancy, its causes, common aversions, and tips to overcome it.

When Does Food Aversion Start In Pregnancy?

A study has found that 54% of pregnant women experienced food aversions during early pregnancy (1). The condition could occur at any stage of pregnancy, but it is more likely during early pregnancy or the first trimester. These aversions may go away as the pregnancy progresses or after you deliver (2).

What Causes Food Aversions During Pregnancy?

The exact cause of food aversion in pregnancy is not known, but researchers have a few theories.

  1. Hormonal fluctuations: Just like the behavioral and physiological changes during pregnancy, food aversions could also be due to hormonal changes. However, there is no connection between food cravings and aversions.
  1. Morning sickness: Nausea is more common during the early months of pregnancy and could be responsible for food aversions. For instance, just the smell of certain foods can make you may feel nauseated (3).
  1. Sensitivity to taste and smell: During pregnancy, a woman’s senses are heightened. Abnormal or increased taste and smell sensitivity could stop you from having any foods. For instance, sensitivity to a bitter taste may stop you from having even tea, coffee or chocolate (4).
  1. Maternal-embryo protection hypothesis: It states that certain mechanisms that don’t allow pregnant women to have foods that contain toxins or pathogens. It is to protect the woman and her baby. This could also be a cause for food aversions (5).

When Should You Call The Doctor?

When you have aversions to spicy food or fried stuff or something manageable, you need not worry much. However, if you are averse to all the healthy foods and experience cravings for non-edible things such as clay or paper (medically known as pica), then you should talk to your doctor.

Your appetite and tastes vary throughout pregnancy, owing to the bodily changes. Instead of worrying about why it is happening, figure out what your body needs. Distract yourself from unhealthy food habits and focus on healthy eating. And when in doubt, talk to your doctor about it and seek your partner’s support.
