Small, protein-rich meals, ginger, and staying hydrated are the most effective ways to calm an upset stomach during pregnancy. Most pregnancy-related nausea starts around week six, peaks between weeks eight and ten, and fades by week 13. That timeline can feel long when you’re in the thick of it, but there are proven strategies that make a real difference.
Why Pregnancy Upsets Your Stomach
Your body produces a hormone called hCG (human chorionic gonadotropin) that rises sharply during the first trimester and peaks between weeks 12 and 14, right when nausea tends to be at its worst. At the same time, rising progesterone and estrogen levels relax the smooth muscles of your digestive tract. This slows down the normal rhythmic contractions that move food through your stomach and intestines, so food sits longer than usual and your stomach empties more slowly. Women who experience more of this disrupted stomach rhythm report worse nausea, while women whose stomach activity stays closer to normal tend to feel fewer symptoms.
Progesterone levels continue climbing throughout pregnancy, and small bowel transit times are longest in the second and third trimesters when progesterone is highest. That’s why some women notice heartburn, bloating, or occasional nausea well beyond the first trimester, even if it’s milder than the early weeks.
Eat More Protein, Less Starch
The classic advice to eat crackers and bland carbs isn’t wrong exactly, but research suggests protein does a better job. In a study of first-trimester women, meals where protein made up 30% of calories significantly reduced both nausea and abnormal stomach rhythm compared to meals heavy in carbohydrates or fat. Larger surveys back this up: women with more nausea and vomiting tended to eat more carbohydrates and less protein overall.
Practical ways to shift toward protein without forcing large meals:
- Spread protein across five small meals rather than three larger ones. Sustained amino acid availability helps stabilize stomach contractions and reduces nausea intensity.
- Keep easy protein at your bedside. Nuts, cheese sticks, yogurt cups, or hard-boiled eggs can prevent the empty-stomach nausea that hits first thing in the morning.
- Pair carbs with protein. If crackers are all you can manage, add a spoonful of nut butter or a slice of turkey. Even a small protein addition helps.
Ginger: How Much Actually Works
Ginger is one of the best-studied natural remedies for pregnancy nausea, and it performs well. In one trial, only 33% of women taking ginger were still vomiting by day six, compared to 80% of those on a placebo. The effective dose is about 1 gram per day, split into smaller portions. A common approach is 250 mg every six hours.
You can get this from ginger capsules (sold in most pharmacies), fresh ginger steeped in hot water, or ginger chews. Ginger ale often contains very little actual ginger, so it’s not a reliable source. If you’re using fresh ginger root, a one-inch piece roughly equals a gram.
Staying Hydrated When You Can’t Keep Much Down
Dehydration makes nausea worse and nausea makes hydration harder, creating a frustrating cycle. Sipping small amounts frequently works better than drinking a full glass at once. Cold or slightly frozen liquids (ice chips, frozen fruit bars, chilled water with lemon) tend to be easier to tolerate. Some women find that drinking between meals rather than with food helps, since liquids alongside a meal can increase that feeling of fullness your slowed stomach doesn’t need.
Electrolyte drinks can help replace what you lose from vomiting. Look for options that provide sodium and potassium without excessive sugar, which can worsen nausea in some people. Coconut water or diluted sports drinks are common choices.
Watch for signs that dehydration is becoming serious: dark or infrequent urination (three or fewer times a day), dry mouth and lips, dizziness, headache, or extreme fatigue. If you can’t keep down more than a few sips of water for 24 hours, you likely need medical attention for IV fluids and vitamins, particularly thiamin, which becomes important after prolonged vomiting.
Wrist Acupressure
Pressing on a specific point on your inner wrist, known as P6, has solid evidence for reducing nausea. A large review found it reduced nausea risk by about 29% and vomiting risk by 30% compared to a fake treatment. To find the point, hold your palm facing up and measure about two finger-widths (roughly 4 cm) above the crease where your hand meets your wrist. The spot sits between the two tendons you can feel when you flex your wrist slightly. Press firmly with your thumb for two to three minutes, or use a commercial acupressure wristband (often sold as “sea bands”) that applies constant pressure.
Antacids for Heartburn and Acid Upset
If your upset stomach is more about acid reflux or heartburn than nausea, calcium carbonate antacids (the active ingredient in Tums and Rolaids) are considered safe during pregnancy when used at recommended doses. Studies have not found an increased risk of miscarriage, birth defects, preterm delivery, or low birth weight at standard amounts. The calcium also counts toward the extra calcium your body needs during pregnancy.
The key is sticking to normal doses. Exceeding the recommended amount can lead to a condition called milk-alkali syndrome, where calcium builds to dangerously high levels. There have also been rare reports of newborn seizures when very high doses were used late in pregnancy. Follow the label, and you should be fine.
When to Ask About Medication
Vitamin B6 on its own is often the first recommendation from providers for pregnancy nausea. If that isn’t enough, a combination of vitamin B6 and an antihistamine called doxylamine (sold together as a prescription product called Diclegis) is the only medication with the FDA’s highest pregnancy safety rating. It has been studied in over 200,000 pregnancies with no demonstrated risk to the fetus in any trimester. The typical starting dose is two tablets at bedtime. If your nausea is disrupting your ability to eat, work, or function, this is worth discussing with your provider rather than toughing it out.
Signs That It’s More Than Normal Nausea
About 1 to 3% of pregnancies involve a severe form of nausea called hyperemesis gravidarum. The hallmarks are losing 5% or more of your pre-pregnancy weight (for example, 7 or more pounds if you started at 140), vomiting multiple times daily, and being unable to keep food or fluids down. Beyond weight loss, warning signs include difficulty thinking or focusing, blurred vision, fainting, muscle weakness or severe cramping, and shortness of breath.
If food or fluids won’t stay down for 24 hours or more, you lose 2 or more pounds in a week, or you vomit blood, contact your provider right away. Hyperemesis gravidarum is treatable, but it typically requires IV fluids and closer medical management to protect both you and the pregnancy.
