Severe GERD in pregnancy: what to know

Pregnancy hormones can relax the muscle between the food pipe and stomach, while the growing uterus can increase pressure on the stomach. Acid may then move upwards, causing a sour taste, burning behind the breastbone, throat irritation, or repeated coughing. Reflux symptoms can be worse after large meals, bending, or lying down. Hiatus hernia may also contribute; see [Hiatus Hernia](/conditions/hiatus-hernia/).

Try smaller meals, remain upright after eating, and avoid lying down soon after food. Notice whether rich, spicy, acidic, or late meals trigger symptoms. Raising the head of the bed can reduce night-time backflow. Drink fluids regularly and ask a clinician or pharmacist which antacid or reflux medicine is suitable in pregnancy; do not start or stop medicines without checking. Persistent symptoms can disturb sleep and may be associated with [Difficulty Sleeping](/symptoms/difficulty-sleeping/).

Arrange medical advice if symptoms are frequent, severe, affecting eating or sleep, or not improving with simple measures. Seek urgent help for chest pain or tightness, trouble breathing, vomiting blood, black stools, repeated vomiting, severe abdominal pain, or difficulty swallowing. Chest symptoms should not be assumed to be reflux; review [Chest Tightness](/symptoms/chest-tightness/) if relevant.

Ask whether your pattern fits reflux, which medicines are compatible with your pregnancy, and whether another cause such as [Acid Reflux](/conditions/acid-reflux/) or [Chronic Cough](/conditions/chronic-cough/) needs assessment. Mention your pregnancy stage, triggers, medicines, swallowing symptoms, and any weight or appetite change.
