Several approaches can reduce morning sickness, from simple dietary changes to supplements and prescription options. The most effective first-line strategies are ginger extract, vitamin B6, and small high-protein meals eaten throughout the day. Most pregnancy nausea peaks between weeks 9 and 14, when 60 to 70 percent of pregnant women experience it, and gradually declines after that.
Why Morning Sickness Happens
For years, rising levels of estrogen and other pregnancy hormones were thought to drive nausea. More recent research from USC and the University of Cambridge has identified a more specific culprit: a hormone called GDF15, produced by the placenta, that increases substantially during pregnancy. The severity of your symptoms depends less on how much GDF15 your body produces and more on how accustomed you are to it. Women who had lower baseline levels of GDF15 before pregnancy tend to get hit hardest, because the sudden spike is a bigger shock to the system.
This also explains some puzzling patterns. Women with certain blood disorders that keep GDF15 chronically elevated are largely protected from pregnancy nausea, because their bodies are already used to higher levels. GDF15 acts on receptors in the brain that trigger the nausea response, which is why the sensation can feel so relentless and hard to override with willpower alone.
Ginger and Vitamin B6
Ginger has the strongest evidence of any non-prescription option for pregnancy nausea. A 2022 meta-analysis found it significantly reduced nausea compared to placebo, though it was less effective at stopping actual vomiting. The recommended dose is up to 1,000 mg per day of standardized ginger extract, split across three or four doses. Practical ways to get it include ginger capsules, ginger tea made by steeping half a teaspoon of grated fresh ginger for 5 to 10 minutes, or ginger ale made with real ginger (most commercial brands use artificial flavoring, so check the label).
Vitamin B6 on its own shows moderate nausea reduction, but the results are inconsistent. The combination of ginger with vitamin B6 produces a larger and more reliable effect than either one alone. A typical combined dose is 600 mg of ginger extract with 37.5 mg of vitamin B6 daily. Both are widely available over the counter.
How to Eat When Nothing Sounds Good
The single most important shift is eating small amounts frequently instead of sitting down to full meals. A full stomach stretches the digestive tract and triggers more nausea. Large bites can also stimulate your gag reflex, so smaller bites of simple foods work better.
Protein-rich foods reduce nausea more effectively than carbohydrate-heavy ones. Think cheese sticks, peanut butter on toast, a protein smoothie, or a handful of nuts. Many women default to plain crackers, which can settle an empty stomach in the short term but won’t keep nausea away as long as something with protein will.
A few other strategies that help:
- Separate food and drinks. Drinking fluids with meals can slow an already sluggish digestive system and worsen nausea. Sip between meals instead.
- Choose cold over hot. Cold foods have less smell, and strong odors are a common nausea trigger during pregnancy.
- Keep snacks within arm’s reach. Getting up to prepare food involves motion and exposure to kitchen smells, both of which can make things worse. A cooler by the bed or couch helps.
- Skip fatty and fried foods. They’re harder to digest and tend to intensify nausea.
If you’re struggling to find anything appealing, it helps to think in terms of texture and flavor rather than traditional food groups. Salty foods like pretzels or salted crackers, tart options like pickles or green apples, bland comfort foods like mashed potatoes or plain rice, and crunchy snacks like celery or carrot sticks are all commonly tolerated. Popsicles, smoothies, and broth can be easier to get down than solid food on the worst days.
Staying Hydrated
Dehydration is the main risk when vomiting is frequent, and it creates a feedback loop: dehydration makes nausea worse, which makes it harder to keep fluids down. Small, frequent sips are more effective than trying to drink a full glass at once.
Electrolyte drinks help replace what you lose through vomiting. Low-sugar options like Pedialyte or electrolyte tablets dissolved in water are better choices than sugary sports drinks. You can also make a simple version at home with half a cup of water, one cup of coconut water, a pinch of salt, and a squeeze of lemon or lime. Broth and clear soups are another good source of both fluid and sodium.
Peppermint tea counts toward your fluid intake and some women find it soothing, though the research behind it is limited. Coffee, citrus juice, and milk tend to make nausea worse for most people and are worth avoiding until symptoms settle.
Prescription Options
If ginger, B6, and dietary changes aren’t enough, the next step is a combination of doxylamine and vitamin B6, which is the only FDA-approved prescription specifically for pregnancy nausea. Doxylamine is actually the active ingredient in some over-the-counter sleep aids, and the American College of Obstetricians and Gynecologists (ACOG) notes that half of a 25 mg tablet provides a 12.5 mg dose. The prescription version uses delayed-release tablets that you start taking at bedtime, with the dose gradually increased over several days based on how well your symptoms respond.
If that combination still isn’t controlling symptoms, your provider may move through a stepwise series of anti-nausea options. ACOG’s treatment guidelines, most recently reaffirmed in 2024, lay out a clear escalation path. The key point is that effective treatments exist at every level of severity, so there’s no reason to simply endure it.
What About Acupressure Wristbands?
Acupressure wristbands target the P6 point on the inner wrist, and they’re widely marketed for pregnancy nausea. A randomized controlled trial of 161 pregnant women tested P6 acupressure against both a placebo band (placed in the wrong position) and a no-treatment control group. All three groups reported significant decreases in nausea and vomiting over the seven-day trial, with no difference between them. The improvement appeared to be a placebo effect. That said, the bands are harmless, and if wearing one makes you feel better, the reason doesn’t matter much in practical terms.
When Nausea Becomes Hyperemesis
Most morning sickness is miserable but manageable. Hyperemesis gravidarum is the severe end of the spectrum, defined by weight loss greater than 5 percent of your pre-pregnancy weight, along with dehydration significant enough to produce ketones in urine. As dehydration progresses, it can cause a rapid heart rate and drops in blood pressure.
The distinguishing line isn’t how often you vomit on a given day. It’s whether you can maintain enough nutrition and hydration to avoid losing weight and becoming dehydrated. If you’re unable to keep any fluids down for 12 or more hours, noticing dark urine, feeling dizzy when standing, or losing weight steadily, those are signs that home remedies aren’t enough and you need medical support, which typically involves IV fluids and stronger anti-nausea treatment. Women who have been vomiting for more than three weeks may also need supplemental thiamine (vitamin B1) to prevent a rare but serious neurological complication.
