Indigestion during the third trimester

Indigestion in the third trimester is often linked to pressure on the stomach and pregnancy-related changes in digestion. Heartburn, fullness, burping, nausea, or an unpleasant taste may become more noticeable after meals or when lying down. Symptoms can be uncomfortable, but they should be considered alongside your pregnancy history and any other warning signs.

As the uterus grows, it can reduce the room available for the stomach. Pregnancy hormones can also relax the valve between the stomach and food pipe and slow digestion, allowing acid to move upward more easily. Similar symptoms may come from Acid Reflux, Gastritis, or a Hiatus Hernia. Severe upper-abdominal pain, headache, vision changes, or sudden swelling is not typical indigestion and should be reported promptly to your maternity team.

Try smaller meals more often, eat slowly, and stay upright after eating. Avoid foods and drinks that reliably trigger burning, and leave space between your evening meal and bedtime. Raise your upper body for rest if your maternity team says this is comfortable. Check every medicine, antacid, or herbal product with a pharmacist, midwife, or doctor; Acid Reflux Medication may be appropriate in pregnancy, but the choice depends on your health and other treatments.

Contact your maternity team if symptoms are difficult to control, stop you eating or drinking, or continue despite practical changes. Seek urgent assessment for severe persistent upper-abdominal pain, vomiting that prevents fluids, blood in vomit, black stools, chest pressure, breathing difficulty, severe headache, visual symptoms, or reduced fetal movement. Do not assume a new severe symptom is ordinary heartburn.

Ask which food changes and medicines are suitable for you, whether your symptoms could reflect another condition, and what signs should prompt a same-day call. Mention any previous Acid Reflux, stomach problems, or medicines used during pregnancy.
