Heartburn during labour: what to know

Contractions, changes in position, recent food, and pressure around the stomach can make reflux feel stronger. The sensation may be burning behind the breastbone, a sour taste, or fluid rising into the throat. Acid reflux can present this way, while gastritis or a hiatus hernia may also cause upper digestive discomfort. Heartburn is not a dependable way to judge how labour is progressing. The midwife or doctor can assess the symptom alongside your contractions, vital signs, and other findings.

Tell your midwife or doctor when the burning began, where it is, and whether it follows a contraction or position change. Follow the team’s advice about sitting more upright, turning safely, and taking sips of fluid. Do not take an unapproved remedy during labour. The team may consider your labour plan, recent food and drink, allergies, and any medicines already given before suggesting relief.

Call the birth team immediately for chest pressure, shortness of breath, faintness, severe or persistent pain, pain spreading to the arm or jaw, vomiting blood, severe upper-abdominal pain, heavy bleeding, or a sudden feeling that something is wrong. These symptoms require prompt assessment and should not be labelled heartburn without examination.

Ask which reflux medicines, if any, are compatible with your birth plan, what you may drink during labour, and how to report chest discomfort. Mention previous reflux, ulcers, allergies, and medicines you use.
