When you're pregnant do you get a stronger sense of smell??

Answer 1

Look at this information:
(You have so good information in number 4)

1:

Nausea with or without vomiting
Morning sickness is one of the telltale signs of early pregnancy. Most women feel some sickness around four to eight weeks of pregnancy, but the queasiness can begin as early as two weeks after conception.

Although nausea and vomiting during pregnancy is commonly called morning sickness, it can occur at any time of the day. It seems to stem from the rapidly rising levels of estrogen produced by the placenta and the fetus. These hormones cause the stomach to empty somewhat more slowly, which could be part of the problem. Pregnant women also have a heightened sense of smell, so a variety of odors — such as foods cooking, coffee, perfume or cigarette smoke — can trigger nausea.

Food aversions or cravings
Turning up your nose at certain foods is often the first hint that you're pregnant. Even the smell of some foods may cause a wave of nausea in early pregnancy. One study suggests that pregnant women experience a unique aversion to coffee in the early weeks of pregnancy. Meat, dairy products and spicy foods are other common objects of repulsion.

Food cravings are common, too. Like most other symptoms of pregnancy, these food preferences can be chalked up to hormonal changes. Pregnant women typically find that their food tastes change somewhat, especially in the first trimester, when hormones have the strongest impact.

Increased sensitivity to odors
If you're newly pregnant, it's not uncommon to feel repelled by the smell of a bologna sandwich or cup of coffee and for certain aromas to trigger your gag reflex. Though no one knows for sure, this may be a side effect of rapidly increasing amounts of estrogen in your system. You may also find that certain foods you used to enjoy are suddenly completely repulsive to you.

Does Pregnancy Make You Smell More ?

No, I don't mean smell in the stinky sense - unless you happen to develop cravings for boiled eggs, cabbage and baked beans - but new research has revealed that part of the brain responsible for smelling grows during pregnancy, at least in rats. This discovery has exciting implications for our understanding of brain function and learning in adults, principally because instances where scientists have managed to track down newly forming brain cells (neurones) in adults are relatively rare.

Until the 1980's it was thought that neurones were only created in the developing embryonic brain, and if they subsequently died in the adult then that was that. Game over, no second chances. This dogma was challenged by studies on songbirds, when researchers discovered that certain types of birds grew more brain cells at the time of year when they had to learn new songs. Presumably, it was argued, the increased number of neurones helped them cope with the learning task. But could this apply to animals? Many were sceptical, until American scientists showed that new neurones could be born in the brains of adult mice and humans. Interestingly, two sites where the new cells were found were the hippocampus (the area of the brain associated with learning and memory) and the olfactory bulb (the "smelling zone"), which is where the pregnant rodents come into the picture.

Researchers in Calgary, Canada, injected pregnant rats with a chemical that specifically labelled newly formed neurones. Intriguingly they found a burst of neurone "birth" amongst cells that contribute to the olfactory bulb, about a third of the way into the pregnancy and also just after the pups were born. The trigger for the increase in cell numbers was found to be the hormone prolactin, which increases during pregnancy.

So what is the purpose of this brain expansion? Other researchers have found that female mice that cannot use the hormone properly also fail to recognise their babies. Some have speculated that this could be because they cannot identify their offspring by smell, a common mechanism in many animal species. Perhaps the increased number of neurones in the pregnant rats helps them to learn the smell of their babies. Even more fascinating, is the observation that levels of prolactin increase in males and females immediately after sexual activity. Maybe this also stimulates the production of brain cells - although nothing has yet been proven. It's certainly worth a try as a chat-up line, though.

But how can such studies help us? One of the most keenly sought Holy Grails of modern medical science is the ability to rejuvenate the human brain and body. By studying the sort of things that can stimulate growth of new neurones, we may be able to repair or enhance our ageing brains. Other groups of researchers have shown that if you place rats in an exciting environment, with toys and physical activities, they will increase in mental power and brain size. Exposure to certain anti-depressant drugs can also lead to the birth of new neurones, while stress and depression prevent this. Sadly, the complexities of the mammalian brain make such experiments difficult to interpret, despite the exciting speculation that can be made from even the simplest results. We are a long way from understanding the signals that cause this new growth, but if we can harness the process, the potential for novel therapies could be enormous.

Sensitivity to Aromas
Another related early symptom of pregnancy is a heightened sensitivity to aromas. Even a favorite aroma, such as the smell of a food or perfume, can make you gag. The smell of fresh mowed grass, the smell of a gas station, smells of various foods, household cleaners, perfumes, cigarette smoke, etc., can all cause you to feel nauseated (see nausea symptom above). This is thought to be yet another side effect of the estrogen that is flooding your body.

Heightened Sense of Smell
The nose knows, especially when you’re pregnant. Here’s how to cope when your sense of smell sends you running for the hills (or the bathroom!).
What it is: During pregnancy, lots of ladies become more sensitive and reactive to the scents around them.

What causes it: As with so many pregnancy weirdnesses, when it comes to your heightened sense of smell you can blame those hormones again. In this case, it’s estrogen that can make every little scent that wafts your way feel like an all-out assault on your nostrils.

What you need to know about it: Almost every pregnant women notices a change in her sense of smell; it’s how significant that change is, and how it affects you, that makes all the difference. For instance, scientists have hypothesized that for some women, it’s this heightened sense of smell that leads to morning sickness. (One study even found that women born without a sense of smell — a condition called anosmia — don’t suffer from morning sickness when pregnant. Almost makes you want to cut off your nose to help your stomach, doesn’t it?)

What to do about it: You can’t cut off your nose, but you can try to avoid scents that drive you crazy (especially those that ramp up your morning sickness symptoms). Some strategies to try:

Cook (and eat) only those foods you can stand to smell. (Brussels sprout? Probably not.)
Leave your windows open whenever possible to banish cooking or musty odors.
Wash your clothes more often then usual, since fibers tend to hold onto odors.
Switch to unscented or lightly scented toiletries, cleaning products, etc.
Ask the people around you to be extra considerate: Request that friends and coworkers go easy on the fragrance and, of course, avoid people who are smoking.
Try to surround yourself with those scents (if there are any) that actually make you feel better. Mint, lemon, ginger, and other herbs are more likely to soothe your nausea than they are to make it worse.

Answer 3

Brussels could be the capital of Belgium and may be the principal seat of the Belgian Royal Family and, also the capital of the European Union and if you wish to know after that it this is actually the place hotelbye . Brussels is a remarkably little, easy-going, and human-sized city for all its importance. Unlike anthers city with their hordes of tourists, Brussels is Belgium's main financial and instructional hub, which provides the city an even more workaday sense than different towns. Here, in Brussels, if you would choose to see, you will receive a proper experience for Belgian living, particularly its fantastic restaurant and café culture. Although Brussels may not have the star attractions of other Belgian neighborhoods, the capital has plenty of to help keep readers entertained for a few days with a clutch of world-class museums and art galleries, along with quirkier sights such as the Atomium, and some great remnants of old structure in the old community quarter.

Answer 4

yes! One can get EXTREMELY irritated that no one else notices an offensive odour, - and most people will think you've gone bonkers, but there it is; most women actually get a (much) stronger sense of smell (and of hearing by the way) when pregnant. No doctor I've come across have been able to explain why.....

Answer 5

Definitely.

My wife was so sensitive to all smells. Cooking smells drove her to distraction.

Because of the increased sense of smell she went off most cooked food. Became kind of funny. She could eat fine at restaurants because she didn't have to smell the food cooking.

Her smell reverted back to "normal" withing days of giving birth.

I think (it has to be) hormone related.

Some good things too. You can smell the roses better! So look at it from that aspect.

All the best. Enjoy. Babies are great. Ours is now 6 months.

Answer 6

Yes, you do. Are you not sure if you are pregnant? If you are not sure..please don't go off of the fact that you suddenly have a stronger sense of smell, get tested.

Answer 7

Yes when you are pregnant you get a stronger sense of smell.

Answer 8

Not only did my sense of smell get stronger the whole of my instincts got sronger and also taste buds.Things I liked the smell of I hated and the same with food. My craving was Rock in stick of rock from the seaside! Where could I buy that in Birmingham at Christmas time friggin no where but had a friend who travelled around a lot and had to buy me bags of the stuff.lol
I believe it is something to with hormones (obvious) but also the mothering instinct for things good and bad like a form of protection to your baby.

Answer 9

Now everyone can cure infertility using this natural remedy http://pregnancyhelps.info
infertility can run in the family and one of the first things the doctor asks you when you go to a fertility clinic is your family history regarding cases of infertility or other reproductive issues.
If infertility is caused by genetic disorder then it's not unusual that one of the kids (your mom) doesn't have it and another does (your aunt).
two months of trying is still to early to be concerned about the fact that you might be infertile and it's also quite early to go to a fertility specialist. Go to a regular Obgyb to get a closer insight and see what ways there are are to improve your fertility rate.
Also remove alcohol, caffeine and cigarettes from your life because they might influence your chances too. Stress is also a risk factor when it comes to infertility.

Answer 10

Yes, and that's a good thing. The more sensitive senses of taste and smell help to keep you away from things that might harm your developing baby.

Enjoy the extra senses while you have them. It will go away soon after your baby is born.

Congrats!

Answer 11

Yes!! It's awful! I have a strong sense of smell anyway but it's 10x worse now. I smell everything!!!! The good, the bad, and the ugly!
