Trigger Warning

I'm going to try my very best to be straightforward in this article so that my readers who are struggling with hyperemesis gravidarum don't have to exert any extra energy to read this. I'm also going to use calm scenes and refrain from mentioning certain triggers more than I have to.

However, to also stay informative, I may use specific words or phrasing that trigger HG symptoms. If you're feeling especially susceptible, hand this article off to a friend and ask them to read it for you and relay the information to you.


What is Hyperemesis Gravidarum?

If you've never heard of it before hyperemesis gravidarum sounds like something you'd say right before performing a magic trick, and in a way it feels like one too. One minute you're healthy, happy and expecting a new little babe and the next - abracadabra - you're sick as a dog and living a completely different life than what you'd expected this pregnancy adventure to entail.

Hyperemesis Gravidarum (or HG) is defined as extreme nausea and vomiting in pregnancy. It's a condition that can only occur during pregnancy, and it is accompanied by weight loss and dehydration. It is sometimes called "severe morning sickness".

It's not contagious and the baby doesn't experience the same effects as the afflicted mother.

My Personal Experience with Hyperemesis Gravidarum

In late winter of 2013 I wasn't feeling so well. For the past week I'd been experiencing vertigo whether I was standing up or in bed trying to fall asleep. Food tasted weird and I was feeling kind of down and anxious. Lo and behold, I was pregnant, and when I saw that positive pregnancy test everything I'd been dealing with began to make perfect sense, although I was surprised I'd felt strong symptoms so early on.

At exactly five weeks pregnant, only shortly after I'd gotten my positive on the pregnancy test, I woke up to my first bout of morning sickness. I was so relieved! I'd been all over BabyCenter that week and knew that getting sick was a sign of a healthy, progressing pregnancy.

I settled back into bed with a sense of deep pride at the chaos the little growing blastocyst was causing my body and tried to nod back off. But almost immediately, the waves of nausea returned and I was back in the bathroom. I thought maybe I needed to eat something to help soothe my stomach. I'd heard that nibbling crackers and sipping on ginger ale helped so I sent my husband to the kitchen to bring me back a little somethin' somethin'.

But that didn't help either. As the sun rose I found myself unable to leave the bathroom because every time I stood back up I had to turn right back around.

Convinced that something was wrong with the pregnancy I moaned to my mother that I needed to go to the doctor or something, but she reassured me that this kind of sickness was totally normal sometimes when you're pregnant. And I mean, mother knows best, right?

Over the next few days, the sickness didn't dissipate, instead escalating so that I was so weak it became difficult to walk or even control my body so that I ended up peeing my pants crawling to the bathroom.

What was supposed to be the loveliest, glowiest and most magical time of my life had reduced me to a potty-training toddler.

I hadn't showered in days, I smelled, my ribs were sticking out, I cried but no tears came and even picturing certain triggers like food or imagining certain smells caused me to throw up.

I was, in every sense, a complete mess.

Things did not get better like my mother promised, and over the next five months I became familiar with every curve of the toilet, every fake space in the tiled linoleum of the bathroom floor. My pajamas hung off my bony body and I was too embarrassed to tell anyone I wasn't dying, I was just growing a baby, so I stayed in my room all through the rest of winter, watching spring blossom out the window.

This story has a happy ending and she's four years old now, standing in front of me tearing through each page of her preschool workbook, not a single indication of the havoc she wreaked on my body.

Then there's the sequel dancing next to her in a diaper, clutching a Happy Meal toy and singing.

Unfortunately, hyperemesis gravidarum is a reoccurring condition that rears it's ugly head with each subsequent pregnancy after it's first experienced.

But what's the difference between HG and plain ol' regular morning sickness?

A lot.

The physical symptoms of Hypermesis Gravidarum can vary but they always include extreme nausea and weight loss.

Physical Symptoms and Side Effects of Hyperemesis Gravidarum

The most obvious symptoms of hyperemesis gravidarum are the physical ones which typically start between 4-6 weeks. They often include:

  • Nausea that does not subside. This is not like the vague queasiness that you might have otherwise experiencing during a hormonal shift, like right before your period or when taking birth control. This is a constant and heavy nausea that is lessened only with medication or briefly after an episode of getting sick.
  • Vomiting several times a day. For each woman this might be a different number. For me it was at least 3-5 times but I had days where I vomited until I couldn't any longer and then dry heaved every 15-20 minutes.
  • Loss of appetite. This is pretty obvious, from the nausea. For me, when presented with a small plate of food it took me at least a half an hour to get up the nerve and interest to try it.
  • Weight loss. This is a side effect of the loss of appetite and vomiting. I lost a total of 15-20 pounds in both pregnancies before the HG subsided (more on that amazing hope later!)
  • Low blood sugar. No food to turn to glucose.
  • Dizziness. Dizziness during pregnancy is not uncommon but can be really extreme with HG. I couldn't walk far without support.
  • Exhaustion and weakness. As a side effect of the dehydration.
  • Sleeplessness. Because nausea persists through the night, it can be really hard to sleep.
  • Sensitivity to smells, sights and sounds. I was very sensitive to smells, especially perfumes, soaps and of course, food. I also found myself sensitive to sights that I perceived as overwhelming or dizzying, including bright colors, patterns and movements, computer and phone screens as well as loud or overwhelming sounds like music and particular television shows. Rather than just experiencing feelings of unpleasantness however, these triggers caused nausea and vomiting.
  • Darkened urine. Because I was unable to hold down liquids much of the time my urine was very concentrated.
  • Infrequent bowel movements. Because I was unable to hold down solid food I only had a bowel movement once every 3-4 days, sometimes more.
  • Stomach pain. I'm not a doctor but I would imagine this was a combination of typical pregnancy pains alongside stomach inflammation, dehydration and muscle pain from frequent vomiting.
  • Throat pain. Constant throwing up made my throat sore and hurt the muscles along it.
  • Dental issues. I lucked out on this one but dental issues are a possible side effect of HG since it's nearly impossible to brush your teeth without becoming sick.
  • Skin issues. Because I was so thin during this time the skin that rested along my jutting bones, especially my hips became bruised and sensitive.

The Differences Between HG and Regular Morning Sickness

To understand the difference between regular morning sickness and extreme morning sickness categorized as hyperemesis, it's important to realize that everything that's experienced during HG can be experienced during morning sickness but to a much less extreme.

Symptoms of Morning Sickness vs. HG

Typical Morning Sickness
Hyperemesis Gravidarum
Nausea is like the hallmark of early pregnancy and you know this if you've watched even one movie involving a pregnancy story line. In typical pregnancy it's common to be nauseous when your stomach is empty, especially in the morning, but it can usually be remedied with a light, bland snack, exercise and medication. It does not interfere too much with your everyday life.
In pregnancies affected by HG, nausea is unrelenting and does not occur randomly or at one time of day. Instead, it's constant and while medication is helpful in taking the edge off, it will not get rid of it.
Vomiting in early pregnancy is normal, even once or twice a day. However, in normal pregnancies you'll be able to recover fairly quickly and look at these as "bouts".
In HG pregnancies it's common to vomit so frequently that you lose track and begin to dry heave. Similar to the worst case of the stomach flu you've ever had, almost nothing stays down, including fluids. Vomiting is violent and can result in broken blood vessels in the throat and eyes and losing bladder control.
Loss of Appetite
Food aversions and loss of appetite are normal in the first trimester but you will still be able to pick foods, however random, to ingest and keep down.
Loss of appetite is dramatic and crosses the line from "not in the mood for" to "hand me a bucket." Almost nothing sounds appealing.
Food Cravings
Food cravings in early pregnancy are normal and can be quite dramatic. Usually these cravings result in a happy tummy.
Food cravings, believe it or not, do happen in HG pregnancies, however they may result in projectile vomiting Cocoa Puffs all over your mother-in-law's shower while her sister is over and can hear everything.
Weight Loss
Losing a few pounds or not gaining any weight at all in your first trimester is totally normal.
Weight loss is drastic and happens quickly. Losing 1-2 pounds or more a week is typical of HG.
Physical symptoms aren't the only bummer part about experiencing HG. Depression and anxiety are also common.

Mental and Emotional Symptoms

Along with physical symptoms, HG brings with it many mental and emotional symptoms and side effects unique to the condition like...

Mental and Emotional Side Effects of HG

When I was experiencing HG it was hard to think clearly, solve problems or hold a conversation because I just couldn't think straight. This was probably do to a lack of energy or nutrition to power my brain.
Depression and Anxiety
Likely due to a mix of factors including not leaving my room much and being sick for a long period of time I found myself crying daily and worrying about the future, especially what kind of mother I would be if I couldn't even handle the gestation period.
Loss of Focus
It became difficult to begin or end anything, even TV shows with plots so I ended up watching episode after episode of Property Brothers.
Along with not being able to leave the house except for doctors appointments, I was also unable to maintain a social life outside of infrequent Facebook logins (because Facebook it turns out, was pretty triggering...) I missed out on many holidays, birthday parties and family gatherings during my pregnancies.
It's also common to feel regret, frustration and anger towards the pregnancy and to feel disconnected from the pregnancy itself.

Common Triggers

A trigger is something that worsens or escalates nausea and induces vomiting.

Common Hyperemesis Triggers Include

  • Overwhelming television shows or movies. This isn't a great time for a Stranger Things binge.
  • Reading or focusing your eyes too much on a phone, tablet or computer screen.
  • Riding in a car which might as well feel like getting on a roller coaster.
  • Thoughts of triggers. Thinking about foods or activities that induce nausea can actually make the nausea worse. Yay.
  • Too much physical activity. While you might have moments that make you feel like your can get up and get a lot done, you'll likely feel worse afterward.

Things That Are Difficult or Impossible to Do With Hyperemesis Gravidarum

  • Drive. Thanks to dizziness and lightheadedness it's not only hard, it's pretty dangerous to drive.
  • Cooking. Cooking involves a lot of triggering sights and smells.
  • Cleaning. Again, the sights and smells of cleaning, along with the physical exertion can be triggering.
  • Socializing or holding a conversation. Talking can make it harder to maintain.
  • Shopping, which can be physically overwhelming.
  • Attending classes or doing homework.


When Does Hyperemesis Gravidarum End?

The timeline for HG's progression is different for everyone, but mine followed the most usual timeline which was:

  • Onset 4-6 weeks. I became sick the first time at 5 weeks and at 6 weeks in my second pregnancy.
  • Peak at 9-13 weeks. For me, my worst weeks were actually weeks 8-10, hands down. This is when I experienced the most pain, weakness and consistent sickness.
  • Relief by 14-20 weeks. By the beginning of my second trimester I was experiencing relief in that I wasn't getting sick as often (I went down to just a couple of times a day then to just a few times a week) and the nausea started to relent with random flare ups. By around week 24 I was bouncing back and able to enjoy my pregnancy and my baby bump.

For some women, they'll experience HG until they give birth, and possibly for a couple of days afterward as the hormones leave their body. Know though, that as uncommon as HG is, having it full-throttle throughout the whole pregnancy is even less common. While I did experience waves of it up until I gave birth, I was through the worst of it by five months.

When to Call Your Doctor

If you recognize that your "morning sickness" isn't normal, you need to call your doctor and discuss treatment options. Not all care providers recognize HG as a serious concern. If your doctor doesn't take your illness seriously or if you're experiencing symptoms of dehydration then you need to head straight to the emergency room for IV fluids.
