Do Pregnant Women Fart a Lot? Why Gas Happens in Pregnancy and How to Get Relief

Quick Answer

Yes, many pregnant women fart and burp more than usual, and it is normal. Pregnancy hormones slow down digestion, and later the growing uterus presses on the intestines, so gas builds up. It does not harm your baby. Smaller meals, eating slowly, gentle activity and limiting fizzy drinks usually help.

If you have found yourself passing wind far more often than before, or feeling bloated by lunchtime, you are far from alone, and there is nothing embarrassing about it. This guide explains why it happens, what actually helps, and the few signs that mean you should call your doctor.

Is It Normal to Have More Gas During Pregnancy?

Yes. Gas, bloating and burping are common in pregnancy, and the NHS lists trapped wind as one of the usual, harmless causes of tummy pain in pregnancy.

It helps to know that farting is normal for everyone. The US National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) says people pass gas an average of 8 to 14 times a day, and up to 25 times a day is still considered normal. In pregnancy, you may simply be at the higher end of that range for a while.

Why Do Pregnant Women Get So Much Gas?

Pregnancy slows your digestion, and slower digestion means more gas. ACOG explains that higher hormone levels in pregnancy can slow down the digestive system, which is also why constipation is so common.

NIDDK explains that gas comes mainly from swallowed air and from gut bacteria breaking down undigested carbohydrates. A smell is common too: NIDDK notes the odour is often due to sulfur in the gas, and it does not mean anything is wrong.

Does Gas Get Worse in Certain Trimesters?

Gas can show up at any stage of pregnancy, but many women notice it most in early pregnancy and again in the last few months. Early on, hormone changes slow digestion; later, the growing baby and uterus take up more space and press on the stomach and bowel.

The NHS says indigestion symptoms such as feeling full, bloated and burping are more likely later in pregnancy, partly because the growing baby presses on your stomach.

Which Foods Can Cause More Gas in Pregnancy?

Some healthy foods naturally produce more gas, but you do not need to cut them out. The NHS and NIDDK list these common triggers:

Dal, vegetables and fruit are important in pregnancy for fibre and nutrients. Instead of avoiding them, increase fibre gradually and drink enough water with it.

How Can You Reduce Gas During Pregnancy?

Small changes to how and when you eat make the biggest difference. These tips come from the NHS and NIDDK:

• Eat smaller meals more often. Five or six small meals are easier to digest than three heavy ones.

• Eat slowly with your mouth closed. Chewing well and not talking while eating means you swallow less air.

• Sit down to eat. Eating on the run makes you swallow more air.

• Avoid fizzy drinks and straws. Both add air to your gut.

• Skip chewing gum and sugar-free sweets. Gum makes you swallow air, and many sugar-free products contain sweeteners that cause gas.

• Stay active. The NHS suggests regular exercise to help digestion. A short walk after meals is a gentle option, if your doctor has not advised rest.

• Treat constipation early. Drink enough water, increase fibre slowly, and talk to your doctor if constipation lasts.

• Wear comfortable clothing. Tight waistbands can make bloating feel worse.

The NHS also suggests peppermint tea for wind. In pregnancy, the NHS advises not drinking more than 4 cups of herbal tea a day, so keep it to a cup or two.

Are Ajwain, Saunf and Jeera Water Safe for Gas in Pregnancy?

Ajwain, saunf (fennel) and jeera (cumin) are common in Indian kitchens, and small amounts used in cooking are a normal part of the diet. However, there is little research on taking them as remedies in pregnancy, so it is best to stick to food amounts.

Avoid concentrated preparations such as ajwain arka, digestive churans or herbal powders unless your doctor approves them. The same goes for antacids, gas tablets, Eno-type powders and laxatives: some are safe in pregnancy and some are not, so always check with your doctor or pharmacist first.

How Can You Tell Gas Pain From Something More Serious?

Gas pain usually comes and goes, moves around, and eases after you pass wind or have a bowel movement. Pain that is severe, constant, or comes with other symptoms needs a check.

When Should You Call Your Doctor?

Gas on its own is harmless, but the NHS advises calling your maternity unit immediately if you have stomach pain along with any of these:

• vaginal bleeding or spotting

• regular cramping or tightenings

• lower back pain

• unusual vaginal discharge or fluid leaking from your vagina

• pain when you pee, or needing to pee suddenly or more often

• your pee looks cloudy, pink, red or brown

• stomach pain that is severe or does not go away after resting for 30 to 60 minutes

Also see your doctor if bloating or tummy ache keeps coming back, you keep getting constipation or diarrhoea, you have lost weight without trying, or you notice blood in your poo, as the NHS advises for anyone with ongoing wind.

Frequently Asked Questions

Is gas an early sign of pregnancy?

Some women notice more gas and bloating early in pregnancy, because hormone changes slow digestion. But gas is very common for many other reasons too, so it cannot tell you whether you are pregnant. A pregnancy test is the reliable way to know.

Can gas hurt my baby?

No. Gas stays in your digestive system and does not affect your baby, who is protected inside the uterus and amniotic sac. The discomfort is yours alone, and it usually eases with simple changes.

Why are farts so smelly during pregnancy?

Slower digestion gives gut bacteria more time to break down food, and NIDDK notes the odour of gas often comes from sulfur. Foods like eggs, cabbage, cauliflower and onions can add to the smell. It is unpleasant but not a sign of a problem.

Why do I burp so much while pregnant?

Burping is common in pregnancy because hormones slow digestion and the growing baby presses on your stomach, which the NHS links to indigestion. The NHS suggests eating small meals often and not eating within 3 hours of going to bed.

Can I take medicine for gas during pregnancy?

Some medicines for gas and indigestion are considered safe in pregnancy, but not all. Do not take antacids, gas tablets, Eno-type powders, churans or laxatives without checking with your doctor or pharmacist first.

Does iron supplementation cause gas and constipation?

Iron tablets can cause side effects such as constipation, tummy pain and feeling sick, according to the NHS, and constipation can make gas and bloating worse. The NHS suggests taking them with or soon after food, and says it is important to keep taking them. Ask your doctor if they are upsetting your stomach.

Is it normal to feel bloated all the time in pregnancy?

Feeling bloated often is common, especially later in pregnancy. But bloating or tummy ache that keeps coming back, or comes with weight loss, ongoing diarrhoea or constipation, or blood in your poo, should be checked by your doctor.

Can constipation cause more gas in pregnancy?

Yes. When stool stays in the bowel longer, gas builds up and bloating gets worse. Drinking enough water, eating fibre gradually and staying active can help both. For more tips, read our guide on constipation in early pregnancy.

Final Thoughts

Gas and farting are among the most common, and least talked about, parts of pregnancy. It is your body doing its job, not a sign that something is wrong. Eat small meals slowly, keep moving, go easy on fizzy drinks, and call your doctor if pain is severe or comes with bleeding, fever or regular tightenings. Fibre-rich fruit like pears in pregnancy can help keep things moving, as long as you add them gradually.
