Morning sickness: Consider it the first of many concessions you’ll make to your child in your journey as a mother. The swirly-head nausea and vomiting that often accompanies early pregnancy is far from fun—in fact, it can be downright debilitating. Unfortunately, for many expectant mothers, it’s par for the course. Read on for what’s thought to cause it and ways to find some morning sickness relief.

What Causes Morning Sickness

Morning sickness is very common: Nausea and vomiting impacts 70 to 80 percent of all pregnant women. But as widespread as it is, no one knows exactly what causes morning sickness. Experts say it likely relates to the rising rush of hormones coursing through your body when you first become pregnant. The main culprit: Human Chorionic Gonadotropin (hCG), a hormone produced by cells formed in the placenta—the one that essentially tells your body you’re pregnant.

“Morning sickness is probably under-researched and under-appreciated, but we do know it correlates pretty well with the hormone hCG,” says Matthew Hoffman, MD, chair of obstetrics and gynecology for Christiana Care, noting that hCG levels in pregnant women tend to peak at 10 weeks, about the same time that morning sickness does too. “There are a lot of thoughts about why mothers get it, and most project that at that time in pregnancy—when baby has minimal nutritional needs and all organs are forming—it may be a way to prevent moms from ingesting things that are toxic to baby.”

The higher levels of hCG in your body, the more apt you are to suffer from morning sickness. This includes mothers pregnant with twins.

When Does Morning Sickness Start

There are no hard and fast rules for exactly when you’ll first feel nauseous, but typically morning sickness starts in the first or second month of pregnancy and becomes intense at around nine or 10 weeks. “Symptoms depend on the woman and pregnancy, but typically you’ll feel nauseous within the first five or six weeks after you miss your period,” says Julie Visk, CNM, a certified nurse-midwife in the department of obstetrics and gynecology at Thomas Jefferson University Hospital.

While many mothers do feel sick first thing in the morning—less food in your stomach means more gastric acid, which might make your stomach hurt—”morning sickness” is a bit of a misnomer, since nausea can occur any time during the day, triggered by certain smells, foods, size of meals and motion.

How Long Does Morning Sickness Last

For some expectant moms, morning sickness ebbs and flows throughout the day; for others, it might hit at a certain time, like just before midday. Overall, symptoms improve for most women by the end of the second trimester.

“Most people tend to feel it resolving on its own somewhere between 14 and 16 weeks,” says Visk. “Some are unlucky—for them, morning sickness can last until closer to halfway through pregnancy. The really unlucky, maybe 15 percent, may experience morning sickness all the way to the end of pregnancy.”

What Does Morning Sickness Feel Like

Depending on your threshold for pain and discomfort, you may be able to work through the nausea and make it to bedtime. Some expectant mothers feel ill during their commute or while driving; morning sickness can make you prone to motion sickness. It can also be triggered by things like perfume, cooking food or warm, cloistered air. Oh, and watch the drool: Excessive saliva, associated with nausea, can sometimes makes things worse. Drinking water, eating mints or chewing gum might help, says Kelly Walker, CNM, director of the midwifery program at Georgetown’s School of Nursing & Health Studies.

The unluckiest of us find the dizziness and nausea unbearable, as it culminates into stomach pain and persistent vomiting. If your symptoms are relentless—lots of vomiting before you’re nine weeks pregnant—you may be among the 2 percent of pregnant women suffering from severe morning sickness, otherwise known as hyperemesis gravidarum. Signs you might have this acute form of morning sickness include:

  • You’re throwing up five or more times a day
  • You’re losing weight, down 5 percent or more of your pre-pregnancy weight
  • You’re having strong cramps or pain in your belly
  • You have signs of dehydration: you’re not urinating much, your urine is dark, you feel weak, you’re dizzy when you change positions
  • You should call your doctor or midwife if you experience any of these symptoms—they’ll do some lab tests to check how dehydrated you are and may need to give you IV fluids.

Morning Sickness Remedies

So what helps morning sickness? Nausea and vomiting are tough to contend with, but luckily there are several morning sickness remedies out there that can ease your discomfort. Many of them are things you can do at home on your own; if those don’t cut it, there may be some other options your health care provider can recommend. Here, some possible morning sickness treatments.

Home remedies for morning sickness

Talk to your provider about home remedies for morning sickness—you can find many antidotes in your fridge or on your pantry shelves. Scientific research shows that ginger, in many forms, can relieve nausea and vomiting. “Ginger in and of itself as an herb works really well—ginger tea, ginger lollipops, ginger ale,” says Visk, who also recommends cold, fizzy drinks like lemonade or cold water with mint or lemon. “Other good choices of foods are things that are bland and have a lot of carbs versus a lot of fat content, like saltines, chips, toast and foods that aren’t super spicy or aren’t associated with strong smells.”

Other ways to find morning sickness relief:

Eat something small right when you wake up. Having a saltine cracker or two before you crawl out of bed helps neutralize gastric acid.

Eat small, frequent meals. Little amounts of food are easier for your stomach to digest.

Pay attention to what grosses you out. Stay away from food and smells that turn your stomach, and “don’t be adventurous when it comes to new foods,” says Visk.

Don’t lay down right after eating. Your body has a much easier time digesting food when it’s upright; lying down after a meal can lead to indigestion.

Rethink your prenatal vitamin. If you’re regularly throwing up those huge pills, talk to your provider about other options, which may include something with just folic acid, says Visk. Also, try taking your vitamin at night.

Invest in acupressure wrist bands. These little fabric bands relieve motion sickness for some people; they may help when you’re pregnant too.

Morning sickness medication

If home remedies for morning sickness aren’t doing enough to make you feel better, call your healthcare provider. They may recommend taking over-the-counter drugs like Benadryl, Dramamine or a combination of vitamin B6 (three times a day) and doxylamine, otherwise known as Unisom (once a day, at bedtime). For severe morning sickness, there’s a handful of anti-vomiting medications doctors and midwives can prescribe.

What It Means If You Have No Morning Sickness

It’s ironic that in most cases, morning sickness can be a sign that your pregnancy is progressing well. Of course, if you’re lucky enough to feel no morning sickness and baby is growing satisfactorily, there’s nothing to worry about. “You don’t want patients thinking, ‘I don’t have morning sickness but my sister did so there must be something wrong with me,’” says Walker. “That’s not the case—morning sickness is common but not everyone experiences it.”

Visk adds: “Thank your lucky stars and don’t brag too much about it!”

When to Call Your Doctor

Your healthcare provider should spend a good chunk of time at your first pregnancy visit assessing your condition and talking about what to know and expect about morning sickness. If you face symptoms soon after that first visit, call them back and ask to move up your next appointment. “Reaching out early is always better than pining away at home,” says Hoffman, noting that talks with your provider usually help mitigate morning sickness without you having to come into the office or emergency room.

Call immediately if you’re experiencing signs of dehydration or if the morning sickness is impacting your quality of life. “If you’re able to stand and get through your day, you should know that the condition generally isn’t dangerous,” says Visk. “There’s usually an end in sight and babies do just fine throughout morning sickness.”
