What Can You Eat With a Stomach Bug While Pregnant?

When you have a stomach bug while pregnant, focus on replacing lost fluids with frequent small sips of water or an oral rehydration drink. When you feel ready to eat, try small portions of toast, crackers, rice, bananas, potatoes, noodles, or clear soup. Avoid greasy or spicy foods and sugary drinks if they worsen diarrhea. Contact your maternity care team if symptoms persist or you cannot keep fluids down.

Why are fluids the first priority during a stomach bug?

Vomiting and diarrhea can cause your body to lose water and important salts called electrolytes. Replacing these losses is more important initially than eating a full meal. Dehydration can develop when you lose more fluid than you take in, so try to drink regularly even if your appetite is low.

The Centers for Disease Control and Prevention (CDC) recommends drinking plenty of liquids when vomiting or diarrhea causes fluid loss. An oral rehydration solution (ORS), available from pharmacies, can help replace lost water and salts. If you are losing a lot of fluid, ask your pregnancy care team or pharmacist which product is appropriate and prepare it exactly as directed on the package.

Which drinks can you have?

• Plain water: Take frequent small sips instead of drinking a large amount at once.
• Oral rehydration solution: Consider this when diarrhea or vomiting is causing significant fluid loss, following advice from a healthcare professional when needed.
• Clear broth or soup: These provide fluid and may be easier to tolerate when your stomach feels unsettled.
• Ice chips: Sucking on small pieces of ice may be easier than drinking when nausea makes swallowing liquids difficult.

If drinking triggers vomiting, try taking very small sips more often and increase the amount gradually as you tolerate it. Do not rely on fruit juice, fizzy drinks, or very sugary beverages to replace fluids, as they can make diarrhea worse. If you cannot keep even small sips down, contact your maternity care team promptly rather than continuing to manage the problem at home.

What foods are easiest to eat with a stomach bug while pregnant?

There is no single food you must eat to recover. Choose plain, familiar foods that you can tolerate, and begin with small portions. Foods that are relatively bland and easy to prepare may be more comfortable when you have nausea, loose stools, or a reduced appetite.

MedlinePlus, a service of the US National Library of Medicine, lists foods such as crackers, toast, potatoes, rice, noodles, and cooked chicken or fish among options to try when dealing with nausea and vomiting. You can use these choices as a starting point rather than following a strict or restrictive diet.

Plain carbohydrates for quick, simple meals

• Toast or plain crackers: Try a few bites at a time, particularly if strong food smells make nausea worse.
• White rice: Plain rice is a simple option for a small meal.
• Boiled or baked potatoes: Eat them plain or with a small amount of seasoning if tolerated.
• Plain pasta or noodles: Choose a simple preparation without rich, creamy, or spicy sauces.
• Oatmeal or plain cereal: These may be suitable if you find them comfortable to eat.

Fruit and other gentle options

• Bananas: A soft, convenient choice when you want something easy to eat.
• Applesauce: Plain applesauce may be easier to manage than a large serving of raw fruit.
• Clear vegetable or chicken soup: Choose a simple, freshly prepared soup with well-cooked ingredients.
• Well-cooked chicken or fish: When your appetite returns, small portions can help you resume eating protein.
• Cooked vegetables: Try small servings of soft, thoroughly cooked vegetables as you begin to feel better.

Choose clean, properly prepared foods and eat only what feels manageable. You do not need to eat every food on this list. If one food makes your nausea, cramps, or diarrhea worse, leave it aside for now and try another option.

Should you avoid any foods or drinks?

Some foods can be harder to tolerate while your digestive system is unsettled. The NHS guidance on diarrhea and vomiting recommends eating when you feel able and avoiding fatty or spicy foods if they aggravate symptoms. Fruit juice and fizzy drinks may also worsen diarrhea.

For the time being, consider limiting:

• Fried and greasy foods: These may make nausea or stomach discomfort worse.
• Very spicy meals: Hot spices can be uncomfortable when your stomach or intestines are irritated.
• Very sugary drinks: Large amounts of sugar may worsen diarrhea, particularly in fruit juice and some soft drinks.
• Caffeine and alcohol: Avoid alcohol during pregnancy, and limit caffeine according to pregnancy guidance. Water and an appropriate rehydration drink are better choices when replacing fluid losses.
• Foods that seem to worsen your symptoms: If milk or other dairy products increase bloating or diarrhea, temporarily reduce them and see whether you tolerate other foods better.

You do not need to eliminate all dairy products automatically. Pasteurized yogurt or milk may be suitable if you tolerate them, and they can help you return to a varied diet as you recover. Choose products that have been stored safely and are within their use-by dates.

Which food-safety rules matter during pregnancy?

When you are pregnant, it is important to avoid foodborne infections as well as to choose foods that feel comfortable to eat. A food that seems bland is not necessarily safe if it has been stored incorrectly or is undercooked.

The NHS guidance on foods to avoid during pregnancy recommends avoiding unpasteurized milk and certain higher-risk foods, including raw or undercooked meat and raw shellfish. While recovering, choose freshly prepared meals made with thoroughly cooked ingredients, use pasteurized dairy products, wash fruit and vegetables carefully, and refrigerate perishable foods promptly.

If you think your symptoms started after eating a potentially unsafe food, tell your healthcare professional what you ate and when your symptoms began. Fever or flu-like symptoms following a possible foodborne exposure during pregnancy warrant prompt medical advice.

How should you eat while your stomach settles?

You may not feel ready for your usual meals straight away. Start with a few bites, pause, and eat again when you feel able. Several small meals or snacks throughout the day may be easier to manage than three large meals. If food smells make you feel sick, cold or room-temperature foods may be more comfortable, provided they have been stored safely.

Do not force yourself to finish a meal, but keep trying small amounts when you can. As vomiting and diarrhea improve and your appetite returns, gradually resume a varied, balanced pregnancy diet rather than staying on a limited selection of bland foods for longer than necessary. If you have difficulty meeting your nutritional needs or are already struggling with pregnancy-related nausea, ask your midwife or doctor for tailored advice.

When should you contact your doctor or midwife?

It is important to seek medical advice if vomiting or diarrhea prevents you from drinking enough, becomes persistent, or is accompanied by concerning symptoms. Pregnancy can already make nausea and vomiting difficult, and symptoms from a stomach infection or foodborne illness may need a different assessment from ordinary pregnancy sickness.

Contact your doctor, obstetrician, or midwife promptly if you experience any of the following:

• You cannot keep fluids down or continue vomiting despite trying small sips.
• Your urine becomes very dark, you are passing much less urine than usual, or you have not urinated for eight hours.
• You feel unusually weak, dizzy, or faint, particularly when standing up.
• You have a temperature of 38°C (100.4°F) or higher.
• You notice blood in your stool or vomit.
• You have severe or worsening abdominal pain.
• Vomiting or diarrhea is not improving within 24–48 hours, or symptoms are worsening sooner.

The NHS guidance on vomiting during pregnancy advises contacting a midwife or doctor for very dark urine, no urination for more than eight hours, an inability to keep food or fluids down for 24 hours, dizziness, abdominal pain, or a high temperature. Seek urgent medical assessment for severe symptoms rather than waiting for a particular time limit.

If you have signs of severe dehydration, fainting, confusion, severe abdominal pain, or other symptoms that suggest a medical emergency, seek emergency care. Do not delay urgent assessment in an attempt to manage the symptoms by changing your diet alone.

Until you have recovered, prioritize fluids, choose foods you can tolerate, and give yourself time to rest. If you are unsure whether your symptoms are due to a stomach bug, food poisoning, or pregnancy-related sickness, your healthcare professional can consider the timing, symptoms, medical history, and other relevant findings to guide the next steps.
