When Does Heightened Sense Of Smell In Pregnancy Go Away

Having a super sense of smell during pregnancy affects each woman differently. In my case, the more stronger smells such as onions, garlics and meat cooking, laundry powders, perfumes, coffee and cigarette, remained throughout all trimesters of pregnancy. Luckily the onset of nausea and vomiting from strong smells did fade away once I was out of my first trimester.

Psychophysical Measures Of Olfactory Sensitivity

Despite pregnant womens self-reported heightened sense of smell, there was no difference in thresholds between pregnant and nonpregnant women or men. A 1-way ANOVA showed no significant differences in detection thresholds for PEA between pregnant women and nonpregnant women or men = 0.64 P = 0.53). These results are shown in .

Mean threshold ± standard error of the mean for males, nonpregnant females, and pregnant women in experiment 1. The y-axis indicates sensitivity, with 10 indicating highest possible sensitivity on this task.

There were no differences in thresholds among pregnant women in experiment 2, nor in comparison with nonpregnant women as revealed by a 2-way repeated measures ANOVA. There was no main effect of test session/trimester = 2.09 P = 0.13) nor pregnancy status = 0.01 P = 0.91), and no interaction . There was some evidence of a ceiling effect .

When Can I Expect My Hyperosmia To End

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. Of course, if hyperosmia persists, check in with your doctor. An underlying medical condition, and not pregnancy, might be to blame.

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.

Hyperosmia is also associated with hyperemesis gravidarum .

Fluctuations in your HCG levels correlate very closely with the changes in your sense of smell and the intensity of nausea and vomiting. This hormone is probably responsible for the changes in your odor likes and dislikes. For example if morning coffee was your pick-me-up ritual, and now that you are pregnant, you cant stand the smell of your favorite beverage you can blame the HCG.

Important Facts About Increased Sense Of Smell

While some scents may cause instant nauseating reactions, others may only cause a mild dislike. Pregnant women have also reported liking the scents of some things they disliked before becoming pregnant. There is no way to avoid the increased sense of smell during pregnancy, but fighting off the effects may be a challenge.

Why Does Your Sense Of Smell Change

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

The plasma volume 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 thats why you react more strongly to smells, says midwifery teacher Denyse Kirkby, author of My Mini Midwife. Your olfactory centres the receptors that pick up smells may also be affected by this increased flow.

Meanwhile, some people believe its actually a protective mechanism to stop you breathing in anything harmful.

This heightened sense of smell can actually be an early sign youre expecting

Reacting differently to your partners smell? Dont worry youre not going mad.

Pregnancys such an emotional, hormonal time, so if he suddenly smells loads better, that could be something primal kicking in for you, that idea that hell protect you and your baby, says Denyse. Or if youre not so keen perhaps its a different type of protective instinct youre feeling, that you can handle things yourself.

It varies hugely, but the main thing to remember is that this strong sense of smell does tend to pass once your babys born, if not before.

Clinical Or Evolutionary Relevance

Exact Weeks It May Happen

The heightened sense of smell begins from the 8th and lasts approximately until the 12th and 13th weeks. This symptom during pregnancy is associated with other manifestations of toxicosis: nausea, vomiting, and aversion to food.

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.

When Does Your Sense Of Smell Start To Heighten

Most women notice an amplified sense of smell during their first trimester . This is known as hyperosmia and can often be one of the very early signs of pregnancy.

Even the slightest odor can suddenly become overpowering. Certain smells you once despised may now seem quite delightful, while others you had loved may now make your stomach turn. You might even find your partners scent repulsive or possibly more attractive.

Its important to remember that not all pregnancies are the same, and your sense of smell can be different in your first and every other pregnancy. 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.
