Heartburn at Night in Early Pregnancy: What to Know

Heartburn is a burning feeling behind the breastbone, sometimes with a sour taste or fluid rising into the throat. During early pregnancy, hormonal changes can relax the muscle that normally keeps stomach contents from moving upwards. A full stomach and lying flat can then make symptoms more noticeable at bedtime. Heartburn itself does not confirm pregnancy, and symptoms can have other explanations, including acid reflux, gastritis, or a hiatus hernia.

Night-time symptoms may disturb sleep, but occasional discomfort is often manageable. Mention frequent or persistent symptoms at a pregnancy appointment so the clinician can check the pattern and review other medicines or health conditions.

Try eating smaller meals and staying upright after eating rather than lying down soon afterwards. Avoid a large meal close to bedtime, and notice whether particular foods or drinks trigger burning. Raising the upper part of your sleeping position may reduce reflux; use a stable arrangement that keeps you comfortable. Loose clothing around the abdomen can also help.

Do not start an antacid, acid-reducing medicine, or herbal product without checking that it is suitable in pregnancy. A pharmacist, midwife, or doctor can recommend an appropriate option and explain how to take it. If symptoms continue despite these changes, ask about acid reflux medication rather than repeatedly self-treating.

Arrange medical advice if heartburn is severe, keeps returning, prevents sleep, or makes eating and drinking difficult. Seek urgent help for chest pain that is severe, unusual, or accompanied by breathlessness, fainting, sweating, or pain spreading to the arm, jaw, or back. Get prompt assessment for vomiting blood, black stools, repeated vomiting, or difficulty swallowing.

A clinician can distinguish reflux from other causes of upper abdominal or chest symptoms and choose pregnancy-appropriate care.

Ask: Could this pattern be reflux or something else? Which medicine is suitable at my stage of pregnancy? How long should I try lifestyle changes before contacting you again? Are any of my current medicines or supplements making the burning worse?
