📅 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.
