Heartburn at the End of Pregnancy: What to Know

As pregnancy advances, the growing uterus can press on the stomach, while hormonal changes may relax the valve that normally keeps stomach contents down. This can let acid rise into the oesophagus, especially after meals or when lying down. A sour taste, burning behind the breastbone, and fluid coming up are typical reflux features.

Heartburn can be common in late pregnancy, but do not assume every upper-abdominal symptom is reflux. Gastritis, a peptic ulcer, or other pregnancy-related problems can feel different and may need examination.

Choose smaller meals, eat slowly, and stay upright after eating. Avoid lying down soon after food and identify personal triggers such as spicy or fatty meals, coffee, chocolate, or mint. At night, raise your upper body comfortably and keep water nearby for a dry or sour mouth.

Discuss any medicine with your maternity clinician, doctor, or pharmacist before taking it. They can select an option suitable for pregnancy and check for interactions with supplements or other medicines. Do not use leftover treatment without checking the label and your care team.

Seek urgent care for severe or persistent upper-abdominal pain, severe headache, vision changes, sudden swelling, chest pressure, breathlessness, fainting, vomiting blood, or black stools. Contact your maternity team promptly if vomiting prevents fluids, swallowing becomes difficult, or the discomfort feels unlike your usual heartburn. New or worsening symptoms near delivery should be discussed rather than self-treated.

Ask which foods or meal patterns may be aggravating your symptoms, which pregnancy-compatible treatment is appropriate, and how to separate ordinary reflux from warning signs. Mention all supplements and medicines, plus any change in fetal movement or other pregnancy symptoms.
