Morning sickness usually starts around week six of pregnancy, peaks near week 10, and improves by week 14. About 90% of people find relief by week 20. While you’re in it, though, those weeks can feel endless. The good news is that several strategies, from simple dietary shifts to supplements and pressure point techniques, can meaningfully reduce nausea.
Why Morning Sickness Happens
Despite the name, pregnancy nausea can strike at any hour. The primary driver appears to be a hormone called GDF15, produced in the placenta, which increases substantially during pregnancy and acts on receptors in the brain that trigger nausea and vomiting. Rising estrogen levels and a heightened sense of smell also play significant roles. In fact, research published in the American Journal of Obstetrics & Gynecology found that women born without a sense of smell almost never experienced pregnancy nausea, suggesting that smell is one of the most powerful triggers.
This is why strong odors, cooking smells, perfume, or even a partner’s deodorant can send you running to the bathroom. Understanding this connection gives you a practical starting point: reducing your exposure to triggering scents is one of the simplest things you can do.
Eat Protein-Rich Snacks, Not Just Crackers
The classic advice is to nibble on plain crackers or toast. That’s not wrong, but it’s not the best option either. A study published in the American Journal of Physiology tested different meal types in nauseated pregnant women and found that protein-heavy meals reduced nausea significantly more than equal-calorie meals of carbohydrates or fat. Protein also normalized abnormal stomach activity that contributes to the queasy feeling.
In practical terms, this means reaching for Greek yogurt, a handful of nuts, cheese, a hard-boiled egg, or a small portion of chicken instead of relying solely on bland carbs. Keeping these snacks on your nightstand to eat before you even sit up in the morning can help, since an empty stomach tends to make nausea worse. Aim to eat small amounts every one to two hours rather than three large meals. The goal is to keep your stomach from being too empty or too full, both of which amplify nausea.
Stay Hydrated Without Making It Worse
Dehydration makes nausea worse, but gulping water on an upset stomach can trigger vomiting. The key is separating fluids from food. Drink between meals rather than during them, and take small sips throughout the day instead of large amounts at once.
If plain water sounds unappealing, try coconut water, diluted sports drinks, or water-rich fruits like watermelon and grapes. Chewing on ice chips is another option that many people tolerate well when liquids feel like too much. Cold or ice-cold beverages tend to be easier to keep down than room-temperature ones.
Vitamin B6 as a First-Line Supplement
Vitamin B6 (pyridoxine) is one of the most well-supported supplements for pregnancy nausea. The American College of Obstetricians and Gynecologists recommends it as a first step. The standard approach is 25 mg taken three times daily, for a total of 75 mg per day. Clinical trials have shown this dosage is more effective than a placebo at controlling both nausea and vomiting.
B6 is available over the counter and is generally well tolerated at this dose. Some people find it works best when combined with the antihistamine doxylamine, which is the combination found in the prescription medication specifically approved for pregnancy nausea. Talk to your provider about whether the combination makes sense for you, especially if B6 alone isn’t enough.
Ginger: What Works and How Much
Ginger has the strongest evidence of any herbal remedy for pregnancy nausea. Multiple meta-analyses have found it significantly reduces nausea compared to a placebo, and some studies show it works about as well as conventional treatments. No significant adverse effects have been reported in clinical trials.
The most reliable forms are ginger capsules, ginger tea made from fresh root, and crystallized ginger. Ginger ale is less effective because most commercial brands contain very little actual ginger. A common approach is around 1,000 mg of ginger root per day, split into smaller doses. Fresh ginger steeped in hot water for 10 to 15 minutes makes a simple tea you can sip throughout the morning.
Try the P6 Pressure Point
Acupressure at a specific point on the inner wrist, called P6, can help reduce mild to moderate nausea. To find it, place three fingers flat across the inside of your wrist, starting at the crease where your hand meets your arm. The point sits just below where your third finger lands, in the groove between the two large tendons that run down your wrist. Press firmly with your thumb for one to two minutes, then switch to the other wrist.
You can also buy inexpensive wristbands (often sold as “sea bands”) that apply constant pressure to this spot. They’re drug-free and easy to wear all day. The evidence is modest, but many people find them helpful as one piece of a larger strategy, and there’s no downside to trying them.
Manage Your Environment
Because smell is such a powerful nausea trigger during pregnancy, controlling your environment makes a real difference. Open windows when cooking, or better yet, have someone else cook when possible. Switch to unscented soap, deodorant, and laundry detergent. Keep a lemon or a small bottle of peppermint oil nearby to sniff when you encounter an unavoidable smell. Cold foods tend to have less aroma than hot ones, so salads, sandwiches, and chilled fruit may be easier to tolerate than a hot meal.
Other environmental adjustments that help: get fresh air whenever nausea hits, avoid lying flat right after eating (propping yourself up helps keep stomach contents settled), and brush your teeth carefully since putting a toothbrush too far back can trigger gagging when you’re already nauseated.
When Nausea Becomes Something More Serious
About 1 to 3% of pregnant people develop hyperemesis gravidarum, a severe form of pregnancy nausea that goes beyond normal morning sickness. The hallmarks are losing more than 5% of your pre-pregnancy weight, being unable to keep any food or fluids down for 24 hours or more, and signs of dehydration like dark urine, dizziness when standing, or a racing heart.
If you’re vomiting so frequently that you can’t stay hydrated, or if you notice significant weight loss, this needs medical attention. Treatment typically involves intravenous fluids and medications to control vomiting. Hyperemesis gravidarum is not a failure of willpower or a sign that you aren’t trying hard enough. It’s a medical condition driven by your body’s hormonal response, and it requires professional support.
Putting It All Together
Morning sickness rarely responds to just one fix. The most effective approach stacks several strategies: eating small protein-rich snacks throughout the day, sipping fluids between meals, taking B6, using ginger, managing scent exposure, and trying acupressure. Start with the simplest changes and add more if needed. Most people find that the combination of dietary timing, a supplement or two, and environmental awareness brings nausea down to a manageable level, even if it doesn’t disappear entirely, until your body adjusts and symptoms ease on their own.
