Week 28 · Third Trimestermild
Gas and Flatulence at 28 Weeks Pregnant
Gas and flatulence are among the most common and embarrassing pregnancy symptoms. Progesterone slows the digestive tract, and the growing uterus compresses intestines — both cause gas to accumulate.
👶 What's Happening at Week 28
Your baby is now the size of a eggplant.
- The fetus can blink and has developed eyelashes.
- REM sleep begins — the baby may be dreaming.
- The brain triples in weight during the third trimester.
🔬 Why You're Experiencing Gas and Flatulence at Week 28
- Progesterone relaxes intestinal smooth muscle, slowing transit and allowing more gas to form
- Slower digestion gives bacteria in the colon more time to ferment food, producing gas
- Growing uterus compresses intestines, slowing movement
- Certain foods high in fermentable carbohydrates (beans, cabbage, broccoli, onions, dairy)
- Swallowing air while eating quickly or talking while eating
💊 Relief Tips for Week 28
1
Eat SlowlyEating slowly and chewing thoroughly reduces air swallowing and improves digestion.
2
Identify and Limit Trigger FoodsKeep a food diary to identify which foods cause the most gas — common culprits include beans, cruciferous vegetables, carbonated drinks, and some dairy.
3
Stay ActiveRegular gentle movement, especially walking after meals, stimulates intestinal motility and reduces gas.
4
Simethicone (Gas-X)Simethicone is not absorbed into the body and is considered safe in pregnancy. It helps gas bubbles coalesce and pass more easily.
5
Avoid Carbonated DrinksCarbonated beverages directly introduce gas into the digestive system.

Frequently Asked Questions
Is excessive gas normal during early pregnancy?
Yes — gas often increases in the first trimester almost immediately due to rising progesterone levels and is one of the earliest pregnancy symptoms for many women.
Can gas pain feel like contractions?
Gas can cause crampy, wave-like abdominal pain that may briefly resemble contractions. Gas pain is usually relieved by passing gas or a bowel movement; contractions are not.
Is it safe to take Gas-X (simethicone) during pregnancy?
Yes — simethicone is not absorbed systemically and is considered safe during pregnancy.
Can gas during pregnancy hurt the baby?
No — gas is uncomfortable for the mother but has absolutely no effect on the baby.
