Acid reflux while sleeping during pregnancy

Pregnancy hormones can relax the barrier above the stomach, and the growing uterus can increase pressure below it. In bed, this may lead to chest burning, a sour taste, throat irritation, coughing, or waking with regurgitation.

Gravity helps keep stomach contents down while you are upright. That assistance decreases after you lie down, particularly if your stomach is still full. Reflux reaching higher in the oesophagus can irritate the throat and trigger a cough even when heartburn is mild.

Waking because of burning or fluid in the mouth fits a reflux pattern, but breathing difficulty, crushing pressure, faintness, or new severe pain should not be labelled as heartburn without assessment.

Choose a smaller evening meal and remain upright afterward. If a certain food reliably precedes symptoms, reduce that trigger while keeping the rest of your diet varied. Raise the whole upper torso with a firm wedge or safely elevate the head end of the bed rather than stacking soft pillows under the neck.

Sleeping on the left side may reduce reflux for some people. Follow your maternity team's advice about comfortable pregnancy sleep positions. If physical measures are insufficient, ask a clinician or pharmacist to select a pregnancy-suitable medicine and explain how to time it with other tablets.

Book an appointment when symptoms frequently wake you, continue despite sleep and meal adjustments, cause persistent hoarseness or cough, or are accompanied by painful or difficult swallowing. Recurrent vomiting or trouble keeping fluids down also needs clinical advice.

Call for urgent help if chest pain is severe, spreads to the arm, jaw, shoulder, or back, or occurs with sweating, breathlessness, weakness, or fainting. Vomiting blood, passing black stools, or developing severe upper abdominal pain also requires urgent assessment.

Tell your clinician how often you wake, whether you choke or cough, what time you eat, and what you have already tried. Ask how your pregnancy stage, other health conditions, and current medicines affect the safest treatment choice.
