Pregnant and fighting a stomach bug? Here’s how you can feel better.

Getting sick when you’re pregnant can feel especially overwhelming, your body’s going through so many changes already, and now you’re dealing with the discomfort of a stomach bug. While it’s certainly no fun, the good news is that with the right care and a little extra attention, you can find relief and take care of both yourself and your baby. Let’s walk through what you can do to ease your symptoms and help you feel better.

What causes stomach bugs during pregnancy?

Getting a stomach bug while you’re pregnant can feel like one thing too many especially when your body’s already working overtime to grow a tiny human. But take a deep breath: catching a stomach bug doesn’t mean you’ve done anything wrong. These things just happen, and they’re often caused by common, everyday viruses like norovirus or rotavirus. They spread easily through food, water, surfaces, or close contact with someone who’s already sick.

According to the research published by Infectious Diseases in Obstetrics and Gynecology, during pregnancy, your immune system shifts gears to protect your baby, which can sometimes leave you more open to catching bugs you might’ve easily fought off before. That’s totally normal and more common than you’d think.

And sometimes, it’s not even a virus. A stomach bug can also come from foodborne bacteria like salmonella or E. coli, which is why healthcare providers recommend avoiding certain foods during pregnancy (like raw eggs or undercooked meat).

It’s not fun, but the silver lining? Most stomach bugs pass quickly and aren’t harmful to your baby. With rest, fluids, and a little extra self-care, you’ll be back on your feet soon. And remember you’re doing an amazing job, even on the tough days.

Types of stomach bugs during pregnancy

Stomach bugs can sneak up on anyone, but when you’re pregnant, even a mild case can feel a bit more intense. The good news? Most of these bugs are short-lived and manageable with rest and hydration. Here are the common culprits behind that queasy, crampy feeling during pregnancy:

• Norovirus

Often called the “winter vomiting bug,” norovirus spreads like wildfire—especially in places like schools, offices, or large gatherings. It usually causes sudden nausea, vomiting, diarrhea, and stomach cramps. It’s quick to arrive and (thankfully) usually leaves just as fast.

• Rotavirus

More common in young children, but adults (including pregnant people) can catch it too, especially if you’re around little ones. It causes watery diarrhea, stomach pain, and sometimes a fever.

• Food borne illnesses

These bacteria can lurk in undercooked meat, unpasteurized dairy, or even pre-cut fruits and veggies. They don’t just cause stomach upset—they can be more serious during pregnancy, so it’s important to follow food safety tips to protect both you and your baby.

• Traveler’s diarrhoea

Planning a babymoon or just returned from a trip? Changes in food, water, or hygiene standards in new places can sometimes trigger this. It’s usually caused by bacteria or parasites and leads to frequent loose stools, cramping, and fatigue.

• Stomach flu (viral gastroenteritis)

This is a general term for stomach bugs caused by different viruses. It’s not the same as the flu (influenza), but it can definitely make you feel miserable—think vomiting, diarrhea, chills, and exhaustion.

Symptoms of a stomach bug symptoms during pregnancy

Dealing with a stomach bug while pregnant can feel overwhelming, but knowing what to expect can help. Here are the common symptoms:

• Nausea and vomiting

These are the most common, and if you’re also dealing with morning sickness, it can feel extra tough.

• Diarrhea

It can leave you feeling more dehydrated, so hydration is key.

• Stomach cramps and bloating

These can add to your discomfort as your body processes the infection.

• Fever

A mild fever is common but should be monitored, especially if it reaches over 101°F (38°C).

• Fatigue

Between the sickness and your body’s efforts to heal, it’s normal to feel extra tired.

Stomach bug risks by trimester

Getting a stomach bug while pregnant can be tough, but knowing what to expect at each stage can help ease your worries.

• The first trimester

In these early weeks, your baby’s organs are forming, so it’s important to stay hydrated. While a stomach virus won’t harm your baby directly, dehydration can cause some complications, so take extra care of yourself.

• The second trimester

As your baby grows, dehydration can temporarily affect their growth and amniotic fluid levels. Keep fluids down to support both you and your baby.

• The third trimester

Dehydration in the final trimester can lead to preterm labor and lower amniotic fluid. Staying hydrated is crucial to avoid complications and ensure a smooth finish to your pregnancy.

How to treat and recover from a stomach bug during pregnancy

When you’re growing a tiny human, even a simple stomach bug can feel ten times harder. The good news? With some gentle care and a few smart steps, you’ll be on your way to feeling better soon. Here’s what can help:

A stomach bug can cause nausea, vomiting, diarrhea, and exhaustion, but you can manage these symptoms with a little extra care:

• Stay hydrated, little by little

Vomiting and diarrhea can lead to dehydration, which isn’t good for you or your baby. Sip small amounts of water, clear broth, or an electrolyte drink (one with low sugar is best). If water feels tough to keep down, try sucking on ice chips or sipping ginger tea.

• Ease the nausea

Gentle remedies like ginger (in tea, chews, or lozenges) or peppermint tea can help settle your stomach. Some people also find relief with acupressure wristbands—worth a try if you’re feeling queasy!

• Stick to bland, easy foods (when you’re ready)

Once the worst has passed and you feel ready to eat, go for simple, gentle foods like:

1. Toast or plain crackers
2. Bananas or applesauce
3. Boiled potatoes or rice
4. Clear broths or soups

• Get as much rest as you can

Your body is fighting off a virus and supporting your growing baby. Take naps, lie down in a quiet room, and let your body recharge. Even short breaks can make a difference.

When to call your doctor

Most stomach bugs run their course on their own, but don’t hesitate to reach out to your healthcare provider if any of these signs show up:

1. You can’t keep any fluids down for more than 24 hours
2. You have signs of dehydration (dry mouth, dizziness, or not peeing much)
3. You notice signs of early labor (like contractions or pelvic pressure)
4. You have a high fever (over 101°F or 38°C)

It’s always okay to ask for extra support.

What about your baby?

It’s completely normal to worry—but try not to stress. Most common stomach bugs don’t harm your baby. As long as you stay hydrated and get plenty of rest, your little one is safe and sound. If anything feels off, your care team is just a phone call away.

Conclusion 

Being sick while pregnant can really take it out of you but this phase won’t last forever. With some rest, steady hydration, and a little patience with yourself, your body will recover. Go gently, take the time you need, and don’t forget, you’re already doing so much. We’re here for you, every step of the way.
