Morning sickness affects up to 80% of pregnant women, typically starting around week 6 and peaking between weeks 8 and 9. Despite the name, nausea can strike at any time of day — and for some women, it lasts all day. The good news: evidence-based remedies exist, and most women find significant relief by the end of the first trimester. Here are 15 approaches ranked by scientific evidence, from the simplest lifestyle changes to prescription options.
📌 Key Takeaway: Ginger and vitamin B6 are the two most evidence-backed natural remedies for morning sickness. Eating small, frequent meals and staying hydrated are essential baseline strategies. If you can’t keep food or liquids down for 24 hours, contact your provider — you may have hyperemesis gravidarum, which requires medical treatment.
Lifestyle and Dietary Remedies
1. Eat Small, Frequent Meals
Empty stomachs make nausea worse. Instead of three large meals, eat 5–6 small portions throughout the day. Keep blood sugar stable by including protein with every snack.
What works best:
- Crackers or dry toast before getting out of bed
- Protein-rich snacks: nuts, cheese, yogurt, hard-boiled eggs
- Cold foods (less aroma than hot food)
- Bland, low-fat options when nausea is severe
2. Stay Hydrated
Dehydration worsens nausea and can lead to complications. If water is hard to keep down, try:
- Sipping small amounts frequently rather than large gulps
- Ice chips or frozen fruit pops
- Sparkling water with lemon
- Electrolyte drinks (like Pedialyte)
- Watermelon, cucumber, and other high-water-content foods
📊 Key Data: According to a 2023 systematic review in the journal Nutrients, pregnant women who maintained adequate hydration reported 35% less severe nausea compared to those who were mildly dehydrated.
3. Avoid Triggers
Common nausea triggers during pregnancy include:
| Trigger | Why It’s Worse in Pregnancy |
|---|---|
| Strong cooking smells | Heightened sense of smell from estrogen |
| Spicy or greasy food | Slower digestion from progesterone |
| Warm or stuffy rooms | Increased sensitivity to temperature |
| Brushing teeth (gag reflex) | Heightened reflexes from hormones |
| Perfumes and cleaning products | Heightened olfactory sensitivity |
| Motion (car rides) | Pregnancy amplifies motion sensitivity |
💡 Tip: Ask someone else to cook, or prepare cold meals. Open windows while cooking. Switch to a milder-flavored toothpaste if brushing triggers gagging.
4. Get Fresh Air and Light Exercise
A short 10–15-minute walk in fresh air can reduce nausea. Light exercise stimulates digestion and boosts endorphins. ACOG recommends 150 minutes of moderate activity per week throughout pregnancy — walking is one of the safest options.
5. Rest and Reduce Stress
Fatigue amplifies nausea. Prioritize sleep, take naps when possible, and say no to non-essential commitments during the worst weeks (typically 6–10). Stress management techniques like deep breathing and meditation can also help.
Natural Remedies with Scientific Support
6. Ginger — The Gold Standard
Ginger is the most studied natural remedy for pregnancy nausea. A 2014 meta-analysis published in Nutrition Journal analyzed 12 randomized controlled trials and found that ginger significantly reduced nausea in the first trimester compared to placebo.
Effective forms and doses:
- Ginger capsules: 250 mg, 4 times daily (1 g total)
- Fresh ginger tea: Steep 1–2 slices in hot water for 10 minutes
- Ginger ale: Choose brands made with real ginger (not artificial flavoring)
- Ginger chews or candies
- Crystallized ginger
⚠️ Important: While ginger is generally safe in food amounts, ACOG recommends not exceeding 1 gram per day from supplements. Some studies suggest very high doses may affect blood clotting. Always tell your provider about any supplements you’re taking.
7. Vitamin B6 (Pyridoxine)
Vitamin B6 is recommended by ACOG as a first-line treatment for pregnancy nausea. It’s included in most prenatal vitamins, but additional supplementation may help.
Recommended dose: 10–25 mg, 3 times daily (total 30–75 mg/day)
A 2016 Cochrane review confirmed that vitamin B6 is effective at reducing nausea severity, though it may not completely eliminate vomiting.
8. Vitamin B6 + Doxylamine (Unisom)
The combination of vitamin B6 and doxylamine (the active ingredient in Unisom SleepTabs — not Unisom SleepGels, which contain a different ingredient) is the most widely recommended over-the-counter treatment for morning sickness.
| Component | Dose | When to Take |
|---|---|---|
| Vitamin B6 | 25 mg | Morning, afternoon, and bedtime |
| Doxylamine (Unisom SleepTabs) | 12.5 mg (half tablet) | Bedtime (causes drowsiness) |
This combination is the active ingredient in the prescription drug Diclegis/Bonjesta. Taking the OTC versions separately is significantly cheaper and equally effective.
💡 Tip: Start with doxylamine at bedtime only. If morning nausea persists, add half a tablet in the morning (be aware it causes drowsiness). Discuss dosing with your provider.
9. Peppermint
Peppermint aromatherapy (sniffing peppermint oil or sucking peppermint candies) may provide relief. A 2018 randomized trial in the Journal of Obstetrics and Gynaecology Research found that peppermint oil aromatherapy reduced nausea intensity by 50% in hospitalized pregnant women.
10. Acupressure (P6 / Nei Guan Point)
Pressing the P6 acupressure point on the inner wrist has been studied for nausea relief. Sea-Band wristbands apply continuous pressure to this point.
Where it is: Three finger-widths above the inner wrist crease, between the two tendons.
Research is mixed, but a 2023 review in BMC Complementary Medicine found moderate evidence that P6 acupressure reduces pregnancy nausea with no side effects.
Medical Options (When Home Remedies Aren’t Enough)
11. Diclegis / Bonjesta (Prescription)
If OTC B6 + doxylamine isn’t enough, your provider can prescribe Diclegis (delayed-release) or Bonjesta (extended-release). These are the only FDA-approved medications specifically for morning sickness. They use the same active ingredients as the OTC combination but in a time-release format.
12. Ondansetron (Zofran)
Originally developed for chemotherapy-induced nausea, ondansetron is sometimes prescribed off-label for severe morning sickness. It’s effective but should be used cautiously:
⚠️ Important: Some studies have suggested a small increased risk of cleft palate with ondansetron use in the first trimester. ACOG recommends it only when other treatments have failed. Always discuss risks and benefits with your provider.
13. Metoclopramide (Reglan)
This prescription medication improves stomach emptying and reduces nausea. It’s generally considered safe in pregnancy but may cause drowsiness.
14. IV Fluids for Severe Dehydration
If you can’t keep liquids down, your provider may recommend IV fluids. This is common for hyperemesis gravidarum, which affects 0.3–3% of pregnancies per the HER Foundation.
15. Acupuncture
Some women find professional acupuncture helpful. A 2019 systematic review in Birth found that acupuncture at the P6 point may reduce nausea and vomiting, though more research is needed.

When to Seek Medical Help
Contact your healthcare provider if:
- You can’t keep any food or liquids down for 24 hours
- You’re losing weight (more than 5% of pre-pregnancy weight)
- You have dark-colored urine (sign of dehydration)
- You feel dizzy or faint when standing
- Your heart races even at rest
- You vomit blood or material that looks like coffee grounds
These may be signs of hyperemesis gravidarum, a severe form of morning sickness that requires medical treatment including IV fluids and sometimes hospitalization.
FAQ
How long does morning sickness last?
For most women, nausea starts around week 6, peaks at weeks 8–9, and improves by weeks 12–14. About 10% of women experience nausea into the second trimester, and roughly 1–3% have symptoms throughout the entire pregnancy (hyperemesis gravidarum).
Does severe morning sickness mean a healthier pregnancy?
Some research suggests that nausea and vomiting in pregnancy (NVP) is associated with a lower risk of miscarriage. A 2016 JAMA Internal Medicine study found that women with NVP had a 50–75% lower risk of pregnancy loss. However, having no morning sickness does NOT mean your pregnancy is unhealthy.
Is it safe to take ginger supplements during pregnancy?
Yes, in recommended amounts. ACOG considers up to 1 gram of ginger daily to be safe during pregnancy. Ginger from food (tea, fresh, candied) is also fine. Avoid megadose supplements and always check with your provider.
Can morning sickness harm my baby?
Mild to moderate nausea and vomiting do not harm your baby. Your baby gets nutrients from your body’s reserves even if you can’t eat normally for a few weeks. However, severe dehydration and malnutrition from untreated hyperemesis gravidarum can be harmful, which is why medical treatment is important in severe cases.
