How to Survive Nausea During Pregnancy (The Ultimate Guide to Morning Sickness)

If you are experiencing nausea and vomiting during pregnancy, you’re not alone. An estimated 70-80% of women experience these symptoms during pregnancy. For many new moms-to-be, morning sickness is triggered by distinct odors and flavors. For others, there is no rhyme or reason for their discomfort.

We’ve consulted several experienced moms and doctors to bring you a comprehensive list of tips and tricks on how to cope with morning sickness. After all, you want to remember your pregnancy as more than an extended period of queasiness, don’t you?

When Does Nausea During Pregnancy Start?

Many women experience nausea as early as six weeks after implantation. This is because of an increased amount of human chorionic gonadotropin (HCG) in a woman’s system at this time 1(1). Nausea symptoms usually continue for six to nine weeks. As the name implies, morning sickness symptoms tend to be heightened during the a.m. hours. Still, there are plenty of women who experience stomach sickness morning, noon, and night.

What are the Symptoms of Morning Sickness?

Nausea and vomiting are the most common symptoms of morning sickness. However, these discomforts are often accompanied by feelings of fatigue, dehydration, dizziness, and disorientation. Expectant mothers should see a doctor if they suspect their symptoms are a result of something other than a healthy pregnancy.

What Causes Nausea During Pregnancy?

Doctors are not 100% sure of what causes morning sickness. However, most are confident that pregnancy nausea is related to the body’s release of hormones, particularly human chorionic gonadotropin. After all, most women experience nausea and vomiting during the first trimester, when their HCG levels are highest.

While nausea and vomiting are not the most exciting ways to kick off the most magical nine months of your life, they are a good sign that your baby and, in particular, your placenta are starting to take shape.

For many women, morning sickness subsides completely by week 10. This is the stage in which the placenta takes over hormone production.

Nausea Complications

Unfortunately, severe nausea and vomiting can cause several health problems, including:


When you lose more fluids than you take in, you experience dehydration. When dehydration is not resolved, pregnant women must be given intravenous fluids.

Signs of dehydration include:

  • Thirst
  • Tiredness
  • Headaches
  • Dizziness/confusion
  • Constipation
  • Dry mouth or chapped lips
  • Increased/decreased heart rate
  • Dark yellow urine
  • Decreased frequency of urination

Dehydration can be harmful to you and your baby. As such, you must seek medical help if you experience any of the symptoms above. Pregnancy complications caused by dehydration vary from one trimester to the next.

During the first trimester, dehydration can cause overheating, headaches, and urinary tract infections (UTIs). During the first months of pregnancy, dehydration can also directly impact the amount of amniotic fluid in your womb. Low amniotic fluid, which is sometimes called oligohydramnios, is linked to several birth defects and genetic conditions, including umbilical cord compression, joint tightness, and poor lung development 2(2).

During the second trimester, low amniotic fluid has the biggest impact on a baby’s lung development. In extreme cases, developmental issues could lead to infant loss.

During the last trimester, dehydration can cause early contractions and, in extreme cases, even premature birth.

Increased Perspiration

You may notice that you are sweating more than normal now that your hormone levels, blood flow, and body temperature have increased.

If you find yourself sweating excessively, it’s important to make sure you are not suffering from hyperemesis or severe morning sickness. This condition impacts an extremely small number of expectant mothers. However, those that do suffer from hyperemesis are more likely to experience dehydration and other adversities.

Frequent Urination

Morning sickness is often accompanied by the urge for increased urination. Oftentimes, this is due to an increase of hormones and pelvic pressure.

Worn Tooth Enamel

When stomach acid comes in contact with tooth enamel, it can lead to premature erosion. Women who throw up almost every morning are more likely to experience tooth issues during pregnancy. In addition to stomach acid, some nauseated pregnant women experience dry mouth and dehydration, both of which also have the potential to cause tooth decay.

While you may be eager to brush your teeth immediately after you throw up, it’s usually best that you wait and rinse your mouth out inside.

Severe Morning Sickness

In rare cases, severe nausea and vomiting during pregnancy are caused by hyperemesis gravidarum (HG)3(3). Symptoms of hyperemesis gravidarum include nausea, vomiting, weight loss, and dehydration. Women are at a greater risk of developing hyperemesis gravidarum if they have one of the following conditions:

  • Overweight/Obese
  • First pregnancy
  • A multiple pregnancy
  • Trophoblastic disease
  • A previous case of hyperemesis gravidarum

When left untreated, HG can cause several maternal and fetal complications. Babies born to mothers with hyperemesis gravidarum sometimes suffering advanced and even life-threatening neurological and gastrointestinal issues 4 (4). As such, you must get in touch with your medical provider if you are throwing up three or more times per day or if you’ve lost more than 5 pounds since becoming pregnant.

Some women experience such debilitating cases of hyperemesis gravidarum that they are unable to care for themselves or even work. Subsequent malnutrition and dehydration may harm expectant mothers and their unborn babies. As such, it is vital that anyone with extreme symptoms seek out early and aggressive intervention.

Is Morning Sickness Relief Possible?

You should talk with your doctor before considering any over-the-counter nausea remedies. They’ll be able to tell you which treatment help you quash your queasiness. In extreme cases, prescription medications may be necessary. However, there are plenty of simple preventive measures you can take to eliminate your pregnancy-related discomforts.

Take Your Prenatal Vitamins

Studies show that vitamin B6 relieves many of the symptoms of nausea for pregnant women 5(6). According to researchers at the University of Michigan’s School of Medicine, pregnant women should take 10 to 25 mg of vitamin B6 three times per day throughout pregnancy 6(7)6.

With that in mind, excessive intake of vitamin B6 can cause permanent nerve damage in unborn babies. For this reason, expectant mothers must be aware of the dangers of excessive B6 intake. In almost all cases, expectant mothers should be taking no more vitamin B6 than what is in traditional prenatal vitamins.

Your prenatal vitamins help you get your daily dose of essential nutrients even if you aren’t able to keep all of your food down. Of course, some women experience stomach problems when taking ordinary multivitamins. To avoid added discomfort, avoid taking your vitamins on an empty stomach. What’s more, wait until your early morning queasiness passes before popping any pills.

Alter What You Eat

Do your best to avoid trigger foods. Pregnancy is known to alter a woman’s taste and appetite. It should be easy for you to identify and steer clear of the foods and beverages that you find to be intolerable. You might also steer clear of hot foods, which tend to be more flavorful and aromatic.

Furthermore, keep plenty of bland, carb-rich foods on hand. Crackers, dry cereals, toast, and pretzels are just a few of the foods that will help you make it through your first trimesters without going hungry.

Alter When You Eat

Reduce your nausea episodes by breaking your eating schedule into smaller, more approachable meals. Do your best to avoid an empty stomach, which can churn up excessive amounts of stomach acid.

Bland and cold foods and beverages are also known to help nauseous pregnant women. After all, they are less likely to produce strong odors and can be generally soothing.

A study published in the “Primary Care Update for OB/GYNS” showed that 95.5% of doctors recommended that their pregnant patients eat frequent small meals to avoid nausea. Meanwhile, 88.5% of doctors recommended that their pregnant patients with morning sickness snack on soda crackers 7(5).

Stay Hydrated

Regular vomiting can lead to dehydration. Try to drink eight to 10 12-ounce cups of water each day. Healthy fluid intake is good for pregnancy and health in general. Dehydration can exasperate the symptoms of morning sickness. If you’re struggling to keep your liquids down, consider adding some fresh herbs, honey, or fruit.

Take It Easy

If you are experiencing morning sickness, do your best to get up slowly and pace yourself throughout the day. Nausea often keeps pregnant mothers from physical activity, but studies show that moderate exercise may reduce the impacts of morning sickness 8(8). Moderate activity or exercise, such as walking, low-impact yoga, water aerobics, or mild stretching, may help you release endorphins and get some relief from your pregnancy symptoms.

Over-the-Counter Medicines

It’s not a good idea to take over-the-counter morning sickness medications before talking to your provider. They may recommend that you take B6 supplements, ginger, or doxylamine for your nausea. However, only your doctor will be able to say what medications and dosages are safe for you.

Consult a Doctor

If your symptoms are severe enough, your doctor may offer you a prescription for an antiemetic, which is an anti-nausea and vomiting drug. Common morning sickness drugs include antihistamines, vitamin B-6, and dopamine antagonists. Doctors may also prescribe metoclopramide in some extreme cases 9(9).

Give Ginger a Try

Herbs, including ginger, have been known to lessen the complications of pregnancy nausea 10(10). According to a study in Volume 8 of the “Primary Care Update for OB/GYN,” over 50% of doctors recommend ginger to pregnant patients experiencing sickness in the morning 11(11)11.

Ginger is a traditional treatment for gastrointestinal issues. It is proven to have natural antiemetic properties 12(12)
. Of course, not all women appreciate the pungent aroma of this herbal root.

Try Holistic Alternatives

While there is limited research to back up its benefits, many moms swear that acupressure offered them significant relief from morning sickness. A review of 42 acupressure studies showed that direct stimulation of pressure points may eliminate nausea and vomiting in pregnancy patients 13(13).

Some studies also show that targeted acupuncture may be a helpful clinical treatment for nausea and hyperemesis gravidarum 14(14).

Aromatherapy may also help you reduce your chances of nausea and vomiting during pregnancy. In a 2014 study, researchers found that when pregnant women inhaled essential lemon oil, the frequency and severity of their morning sickness was reduced 15(15).

While research is quite limited, some experts recommend hypnosis as a treatment for pregnant women with unresolved hyperemesis gravidarum. Hypnosis may be used to induce a deep state of psychological relaxation 16(16). With that said, only trained hypnosis practitioners should ever attempt this sort of treatment.

Frequently Ask Questions

How is hyperemesis gravidarum diagnosed?

Your doctor will consider your morning sickness symptoms when analyzing your urine and blood samples for signs of dehydration, ketosis, electrolyte abnormalities, and weight loss 17(17).

Is morning sickness worse when you’re having a girl?

Believe it or not, there is a direct but not a concrete link between severe morning sickness and fetal sex. Studies show that severe cases of hyperemesis gravidarum are more likely to be linked to pregnancies with female babies 18(18).

Can morning sickness be harmful to an unborn baby?

While morning sickness is a sign of a healthy and productive pregnancy, it can lead to complications that are potentially harmful to expectant moms and their unborn babies. For this reason, you should be proactive about your nausea. Whenever you have concerns, reach out to your medical provider.

Should I be concerned if my morning sickness stops abruptly?

Morning sickness can change, worsen, or disappear without warning. A sudden change is necessarily indicative of a problem. Your placenta may have taken over the production of your pregnancy hormones, or you might be doing something to lessen your overall symptoms.
