Heightened Sense Of Smell During Pregnancy 


There are numerous symptoms that a mom-to-be experinces. Some of these are really weird and its tough to figure their reasons. Hyperosmia is a heightened and hypersensitive sense of smell that has been associated with a number of medical conditions.


Many women report a heightened sense of smell during pregnancy.

This heightened sense of smell can be traced back to the prehistoric ages when humans did not have safe spaces and had to combat dangerous animals or other human beings all the time. The presence of a new life-form in the body triggered the protective mechanisms present in it, which included the sense of smell to detect any predator or danger and keep yourself safe. It is believed that this high sense of smell assists the mother in sniffing out any toxic food items before consumption that could be harmful to her and the child.


Many pregnant women notice changes in their sense of smell during pregnancy, usually during the first trimester. The significance of these changes and their effect may vary among all expectant moms.

When a women experiences hyperosmia, they can experience smells more strongly than other people. This strong sense of smell may lead them to experience discomfort and illness from certain odors.

People who experience hyperosmia during pregnancy may also experience increased nausea and vomiting. It can also trigger headaches.


But there’s no way to literally train your nose not to be super sensitive while your hormones are surging. You will have to just take this as one of those mom-to-be experiences and wait around until later months or after your baby is born. Pregnancy-induced hyperosmia tends to go away after the pregnancy ends and hormone levels return to normal.


There are different theories, but all revolve around the different processes going on while you’re growing your baby.

The plasma volume (blood flow) in your body increases by up to 50 per cent in pregnancy, so anything moving from your blood to your brain reaches it faster and in larger quantities. This heightens your responses and some experts think that’s why you react more strongly to smells.


How to bring it under control?


Although you cannot really find a way to erase this symptom but there are other ways that you can keep in mind. You can follow them to avoid an overwhelming situation on a regular basis. You can also keep your regular people aware of your condition. Ask your colleague, friends, family members to be sensitive to your new superpower of smell and maybe go easy on their cologne around you.
