Summary Read the full fact sheet

A heightened sense of smell, or hyperosmia, is common during pregnancy, especially in the first trimester, and is linked to hormonal changes like increased estrogen and hCG levels. This sensitivity can make everyday smells—such as food or perfume—feel overwhelming and trigger nausea or vomiting, often worsening morning sickness. While it can be uncomfortable, hyperosmia is generally harmless and considered a normal part of pregnancy.

Ah, the pregnancy superpower nobody warned you about! Suddenly your nose is picking up everything—and I mean everything. About two-thirds of expectant moms develop this super-smell ability, and let me tell you, it’s not always fun! That cup of coffee you used to love? Your favorite perfume? Even your adorable pet? They might suddenly send you running for the bathroom. Trust me, you’re not alone in this sensory adventure!

This heightened smell sensitivity is all thanks to those pregnancy hormones doing their thing, especially during the first trimester. It’s completely normal, even if it feels totally bizarre! Many women notice these changes as one of the early pregnancy symptoms, especially when tracking signs of pregnancy after sex.

Smell and Food Aversion

Just when you thought morning sickness was challenging enough, many expectant mothers discover another surprising pregnancy symptom—a superhuman sense of smell! Suddenly the world becomes a landscape of intense odors, both pleasant and not-so-pleasant. This blog will help you understand what’s happening with your powerful pregnant nose and how to cope when ordinary scents become extraordinary challenges. From food aversions to strange cravings, we’ll cover everything you need to know about this fascinating pregnancy phenomenon!

 

What is smell sensitivity in pregnancy?

Smell sensitivity is one of those commonly self-reported early pregnancy symptoms that catches many women by surprise! It’s like your nose suddenly got an upgrade—picking up scents you never noticed before. Many pregnant women find themselves with this super-sensitive sniffer, which can unfortunately lead to some pretty strong aversions or that queasy feeling when certain scents waft by. It’s your body’s way of going into protective mode for your little one!

 

When does this smell superpower kick in?

Would you believe it can start just days after conception? Yep! Most women notice their nose going into overdrive between weeks 4 and 8. It’s like your estrogen levels suddenly decided to turn the volume up on every scent around you. Some smells that never bothered you before might suddenly feel like they’re screaming for attention!

 

Will my nose ever calm down?

 Good news! For most moms-to-be, this smell sensitivity peaks early and starts to fade by the end of the first trimester (around weeks 13-16) as those hormones finally decide to chill out a bit. Some women do experience it throughout pregnancy, but most find relief around the same time morning sickness waves goodbye. Phew!

 

What smells might suddenly become your enemies?

 Watch out for these common triggers:
Foods – Onions and garlic suddenly smell like they’re from another planet! Uff
Detergents – Those “fresh scent” cleaning products? Not so fresh anymore!
Smoke – Even a whiff of cigarette smoke can send your stomach into rebellion
Scented candles – Those artificial fragrances might leave you congested and miserable

 

Could my food aversions be a pregnancy sign?

If you’re suddenly turning your nose up at your favorite foods or feeling disgusted by smells that never bothered you before—surprise! It might be an early pregnancy clue! That burger joint you used to love? Now just driving past it makes your stomach do flip-flops! This sudden food distaste is your body’s quirky way of saying “Hey, something’s different here!” So if you’re wondering why the smell of coffee is suddenly making you dash for the bathroom, it could be your body’s early alert system telling you there’s a baby on board!

What about those weird food cravings?

On the flip side, those random food cravings can kick in as early as one week after conception! Thanks to those pregnancy hormones that get to work right away, you might find yourself suddenly NEEDING pickles at midnight or desperately craving chocolate like never before. Maybe you’re suddenly enjoying mangoes when you never cared for them, or weirdly obsessed with something you wouldn’t have touched before! Don’t worry—these surprising cravings are totally normal. Your body is just going through some pretty amazing changes!

How to manage your new superpowered nose

You need to make some small changes to your daily routine which can go a long way in making life more bearable. Here are some strategies that might help: • Eat smart – Stick to foods your stomach can handle. Developed an aversion to chicken or cauliflower? It’s totally OK to avoid them for now!
Welcome fresh air – Keep those windows open and get that air flowing! Good ventilation is your best friend when cooking smells or musty odors start bothering you.
Keep clothes fresh – Those lingering odors on clothes can be major triggers, so keep everything clean and odor-free
Go mild with scents – Time to put away those strong perfumes and switch to milder options.
Embrace the good smells – Surround yourself with scents that actually make you feel better! Mint, lemon, ginger, and cinnamon can be real lifesavers during this time.
Stay hydrated – Drinking plenty of water helps with nausea and might even take the edge off that smell sensitivity.
Snack wisely – Small, light snacks can settle your queasy stomach. Try plain khakra, idli, upma, or poha—they’re gentle options that won’t produce strong odors. Fruits like bananas and apples can be your best buddies too!
