Gas & Bloating
Excessive gas, bloating, and abdominal discomfort caused by slowed digestion.
Sources: ACOG, NIH | Last updated: March 2026
📅 When It Occurs
Throughout pregnancy, often worst in first trimester
📊 How Common
About 70% of pregnant women experience increased gas
Overview
Gas and bloating are embarrassing but extremely common pregnancy symptoms that can make you feel uncomfortably full and gassy. About 70% of pregnant women experience increased gas during pregnancy.
Progesterone relaxes smooth muscle throughout your body, including your gastrointestinal tract. This slows digestion, allowing more time for gas to build up. As pregnancy progresses, your growing uterus also puts pressure on your intestines, further slowing things down.
While uncomfortable and socially awkward, gas and bloating are harmless to you and your baby. The same hormones and physical changes that cause gas also contribute to constipation, creating a perfect storm of digestive discomfort.

❓ Frequently Asked Questions
Is gas and bloating an early sign of pregnancy?
Yes. Increased gas and bloating can be one of the earliest signs of pregnancy, often appearing before a missed period. Rising progesterone begins to relax the muscles of your digestive tract soon after conception, which slows digestion and lets gas build up. Because these same symptoms also happen right before your period, gas alone is not a reliable pregnancy test — but combined with a missed period, nausea, or tender breasts, it can be an early clue.
How can I relieve pregnancy gas and bloating fast?
For quick relief, take a 10–15 minute walk to help trapped gas move through your intestines, sip warm peppermint or ginger tea, and gently massage your abdomen. Loosen any tight clothing around your waist, and try lying on your left side or getting into a knees-to-chest position to ease trapped wind. Longer term, eat smaller meals slowly, cut back on carbonated drinks and known gas-producing foods, and stay well hydrated to prevent the constipation that makes bloating worse.
Can trapped gas or bloating hurt my baby?
No. Gas, bloating, and even sharp trapped-wind pains are uncomfortable but completely harmless to your baby, who is cushioned and protected inside the uterus. Your intestines sit separately from your womb, so gas pressure does not reach or squeeze the baby. However, if abdominal pain is severe, constant, one-sided, or comes with fever, vomiting, bleeding, or an inability to pass gas or stool, contact your doctor to rule out other causes.
Is it safe to take Gas-X (simethicone) during pregnancy?
Simethicone, the active ingredient in Gas-X, is generally considered safe in pregnancy because it works only in your digestive tract and is not absorbed into your bloodstream, so it does not reach the baby. Many doctors consider it a reasonable option for stubborn gas. Even so, always confirm any medication — including over-the-counter products — with your own healthcare provider before taking it during pregnancy.
Why is my pregnancy gas and bloating so much worse at night?
Gas often feels worse in the evening because a full day of eating means more food is fermenting in a slowed-down digestive system, and lying down makes trapped gas harder to pass. Eating your largest meal earlier in the day, avoiding carbonated drinks with dinner, taking a short after-dinner walk, and sleeping on your left side can all reduce nighttime bloating and discomfort.
