Why heartburn happens

Heartburn happens when stomach contents move back up into the esophagus. During pregnancy, hormones and pressure from the growing uterus can contribute.

  • Symptoms can vary by meal timing, position, and pregnancy stage.
  • Severe or unusual symptoms deserve a care-team conversation.
  • Chest pain, trouble breathing, or severe symptoms should be treated urgently.

Small habits that may help

Gentle changes are often the first step before medication decisions.

  • Try smaller meals if large meals trigger symptoms.
  • Avoid lying down soon after eating if that worsens reflux.
  • Notice specific foods that repeatedly trigger symptoms for you.

Medicine questions

Your provider can tell you which medicines are appropriate for your pregnancy and medical history.

  • Ask before starting frequent antacids or reflux medicine.
  • Mention vomiting, weight loss, trouble swallowing, or severe pain.
  • Bring a list of medications and supplements you already use.
