As with some other changes that occur during pregnancy, pregnant women usually also experience changes to the sense of smell that becomes more sensitive. This condition is caused by increased levels of estrogen hormones in their body.
According to Howstuffworks, a 2002 study conducted by Philadelphia’s Monell Chemical Senses Center suggests that women with high levels of estrogen hormone has a greater sensitivity. This condition can also occur in women during the fertile period.
The researchers said that higher sensitivity to smell and taste are experienced by pregnant women, and this can sometimes trigger morning sickness, and they became more selective in choosing.
Yet on the other side of the researchers, it is thought that this could be beneficial because it would protect pregnant women from foods that contain chemicals and toxins that are harmful to the fetus.
This condition usually occurs early in pregnancy when the body still has to adapt to changes that occur during pregnancy, especially the fluctuation of hormones in the body. But not all pregnant women have high sensitivity to certain smells.
A study showed some smell from food or beverages such as coffee, meat, dairy products and some sharp spicy foods are generally not favored by pregnant women in early pregnancy.
To overcome it, pregnant women should try to avoid the smell that can aggravate the condition, they can ask their partner not to use perfumes that they do not like, and they should avoid the smell of certain foods.
They can also overcome it by opening the windows to provide good ventilation to allow the exchange of air or by smelling soothing aroma of mint, lemon or other scents they like.
