Heartburn When Lying on the Right Side in Pregnancy

The position of the stomach and the lower oesophageal valve can affect how easily contents move upwards. Some people notice more burning on the right side, while others find that position comfortable; there is no single sleep position that suits everyone. Pregnancy can add pressure around the stomach and can relax the valve, making sour taste, chest burning or throat irritation more noticeable after meals. The symptom points to a reflux pattern, but it does not identify one cause. Gastritis or a hiatus hernia can feel similar.

Try turning to the side that reduces symptoms, and raise your chest and upper back with a wedge or gentle bed elevation. Keep the abdomen supported with pillows if that improves comfort, but avoid arrangements that strain your neck or make breathing difficult. Leave time between an evening meal and lying down, use smaller portions, and identify personal food triggers rather than removing many foods unnecessarily. If medication is needed, ask a maternity clinician or pharmacist about acid reflux medication that fits your pregnancy and other medicines.

Seek advice if changing position does not help, symptoms repeatedly disturb sleep, or you have vomiting, trouble swallowing, black stools or significant upper-abdominal pain. Get urgent help for severe chest pressure, breathlessness, fainting, sweating or pain that travels to the arm, back or jaw. Do not attribute these warning signs to a sleeping position.

Ask whether your symptoms match reflux, which sleeping arrangement is comfortable and suitable for you, whether treatment is needed, and what change should prompt a review.
