What should you know about major heartburn pregnancy?

Pregnancy-related hormonal changes can relax the valve between the stomach and food pipe, while the growing uterus can increase pressure on the stomach. Acid reflux may cause burning behind the breastbone, sour fluid in the mouth, belching, or symptoms after meals and when lying down. Gastritis, a hiatus hernia, or a peptic ulcer can also cause upper abdominal discomfort. Heartburn is not the same as every type of chest pain.

Try smaller meals, eat slowly, and remain upright after eating. Identify personal triggers such as fatty meals, spicy foods, chocolate, coffee, or acidic drinks rather than removing foods unnecessarily. Raise the upper body when resting and avoid eating close to bedtime. Ask a pharmacist or antenatal clinician before taking an antacid or acid reflux medication, because pregnancy, other medicines, and health conditions affect the safest choice.

Get urgent help for chest pressure, breathlessness, sweating, faintness, pain spreading to the arm or jaw, vomiting blood, black stools, or severe abdominal pain. Contact your maternity or primary-care team if symptoms are frequent, interfere with eating or sleep, cause repeated vomiting, or do not improve with pregnancy-safe measures.

Ask whether your symptoms fit reflux, which medicines are suitable at your stage of pregnancy, and whether another cause should be checked. Discuss warning signs and how long to try lifestyle measures before review.
