Pregnancy Symptoms

Pregnancy and Smell Sensitivity

smellDuring the first trimester of pregnancy, many women notice a significant increase in their sensitivity to smells. Certain odors, which may have been easily tolerable before, can suddenly become overwhelming and even trigger bouts of morning sickness. This phenomenon is not uncommon and is often linked to the surge of pregnancy hormones, particularly estrogen.

The Role of Estrogen

Estrogen, one of the primary hormones responsible for maintaining a healthy pregnancy, plays a pivotal role in smell sensitivity. As estrogen levels rise, the olfactory senses become more acute, causing expectant mothers to perceive smells more intensely. While this heightened sense of smell can be intriguing, it can also be accompanied by some challenges.

Dealing with Morning Sickness

The association between smell sensitivity and morning sickness is a well-known aspect of early pregnancy. Certain odors that never bothered you before may now trigger nausea. Coping with this can be a part of your daily routine during the first trimester.

Managing Smell Sensitivity

While you can’t entirely avoid smells, there are strategies to help manage heightened smell sensitivity during pregnancy:

Avoid Triggers

Identify specific smells that trigger nausea and do your best to avoid them. This might include avoiding certain foods or staying away from strong-smelling environments.


Ensure proper ventilation in your living space. Fresh air can help dilute strong odors.

Experiment with Aromatherapy

Some scents can be soothing and even help alleviate nausea. Experiment with gentle aromatherapy, such as lavender or mint, to see if they provide relief.

Stay Hydrated

Proper hydration can help mitigate nausea. Drinking water can help flush out smells and toxins.

Frequent, Small Meals

Eating small, frequent meals throughout the day can help stabilize blood sugar levels and reduce the chances of feeling nauseous due to strong odors.


Ginger is a natural remedy that has been used for centuries to ease nausea. You can try ginger tea or ginger candies.
