How does Pregnancy Affect Your Senses of Smell and Taste

Having a super sense of smell during pregnancy affects each woman differently.

Body Odor &  Pregnancy

Your super-keen sense of smell should diminish by the end of the first trimester, around the time morning sickness usually fades, and as your hormones stabilize. Most women notice it completely dissipates by the end of pregnancy, meaning you should be able to say goodbye to those overpowering aromas by the time you deliver.

How Do I Know That Im Pregnant Without Taking A Test

The most common early signs and symptoms of pregnancy might include: Missed period. If youre in your childbearing years and a week or more has passed without the start of an expected menstrual cycle, you might be pregnant. Tender, swollen breasts. Nausea with or without vomiting. Increased urination. Fatigue.

The Question About Forgetfulness

While a number of women like my friend complain that pregnancy has made them more forgetful than usual, the research on this topic is mixed. Like most changes that occur during pregnancy, hormonal fluctuations are an obvious possible culprit. Some women report no cognitive changes during pregnancy.

A 2008 meta-analysis reported that, compared with women who werent pregnant, pregnant women perform worse on some measures of memory. In particular, pregnant women tend to perform worse on working memory and free recall tasks.

In a study published in 2014, researchers in the UK administered a spatial recognition memory task to non-pregnant women, as well as to women during each trimester of their pregnancy. Compared with their first trimester, pregnant women scored, on average, 11.7% lower on the memory tasks with each subsequent trimester. When the researchers compared memory test scores to levels of six different hormones measured from blood plasma, however, there was no association in other words, hormones may not be playing a role in these memory deficits.

Although theres a lot we dont know about all the crazy changes that happen during pregnancy, one thing is clear: babies do a great job of making their presence known well before they come kicking and screaming into the world.

Stronger Sense Of Smell

According to many women, a heightened sense of smell, called hyperosmia, is one of their earliest signs of pregnancy. Although anecdotes of hyperosmia have existed for a century, scientific literature on the topic is sparse. Subjectively, around two-thirds of women rate their sense of smell as stronger than usual while pregnant. Another study reported that, compared with women who arent pregnant, pregnant women are particularly sensitive to odours such as cooking foods, cigarette smoke, spoiled food, perfumes, and spices.

A few studies have examined scent detection thresholds in pregnant versus non-pregnant women. But, in a study where six different scents were tested, there was no difference in detection threshold between the two groups.

Given the inconsistency between subjective and objective reports on hyperosmia, research suggests that pregnant women dont necessarily have a stronger sense of smell, but are perhaps better at identifying smells. A recent study found that pregnant women were more likely to rate a variety of smells as significantly less pleasant than non-pregnant women. Early in pregnancy much like the body rejects foods that may be toxic to the developing foetus it appears that women have a greater disgust sensitivity that motivates them to avoid other possible contaminants. That may explain why things like cigarette smoke and spoiled food become particularly pungent.

If you are pregnant and youre not experiencing the heightened sense of smell, it doesnt mean that you wont become a superhero sniffer in your subsequent pregnancies.

New Evidence Connects Nausea To Sense Of Smell

Based on data from a pilot study,Stanford researchers hypothesize that the “morning sickness” manywomen experience during pregnancy may be connected to a heightenedsense of smell.

Richard Blum, MD, and LeRoyHeinrichs, MD, both of gynecology and obstetrics at Stanford’sSchool of Medicine, have co-authored a new book that surveys theliterature on women’s nausea and vomiting and presents new researchto support this hypothesis. Blum, an emeritus consulting professor,and Heinrichs, active emeritus professor, have been invited tospeak on the topic of nausea and vomiting in pregnancy at a Sept.20-21 conference sponsored by the Pregnancy branch of the NationalInstitute of Child Health and Human Development.

“Our research suggests that almostall of the stimuli for pregnancy nausea and vomiting are odors,”Blum said, “probably as a result of the hyperacuity of theolfactory system induced by estrogen, which rises duringpregnancy.”

Data from earlier studies revealthat when women have nausea during pregnancy they are less likelyto miscarry. The finding is thought to follow from the fact that ahealthy placenta produces estrogen in the early part of apregnancy if the placenta is not producing estrogen — andtherefore not heightening the woman’s olfactory sensitivity to thepoint of nausea — then there is an associated problem with thepregnancy and thus a greater likelihood of miscarriage.
