Contents

Heartburn, a common symptom experienced by expectant mothers, occurs when stomach acid flows back into the oesophagus, resulting in a painful, burning sensation in the upper chest. It is common in the second and third trimesters, affecting between 30 to 50% of pregnant women. Let’s explore the causes, risk factors, and effective GP-approved treatments for heartburn in pregnancy.
What causes heartburn in pregnancy?
Hormonal changes and physical pressure from the growing uterus (womb) cause heartburn in pregnancy.- Hormonal changes: During pregnancy, the body produces more progesterone, a hormone that relaxes smooth muscle, including the lower oesophageal sphincter (LES), a muscular barrier that separates the stomach from the oesophagus. When relaxed, stomach acid can flow back into the oesophagus (gullet), resulting in heartburn.
- Physical pressure: As the pregnancy progresses, the growing uterus puts pressure on the stomach, which increases the risk of gastro-oesophageal reflux whereby stomach acid is pushed upward into the oesophagus.
Symptoms of indigestion and heartburn

- Sour or bitter taste in the mouth

When does heartburn in pregnancy start?
Heartburn in pregnancy usually starts in the second trimester (around 13 to 26 weeks) but may start earlier for some women. The hormonal shifts that relax the lower oesophageal sphincter (LES) and the physical pressure from the expanding womb often become more pronounced during this period, making heartburn more likely.For many women, heartburn may intensify in the third trimester (27 weeks and beyond), as the uterus continues to expand, putting additional pressure on the stomach. However, some women may experience heartburn throughout their pregnancy, while others may not experience it at all.
What is heartburn in pregnancy a sign of?
Heartburn during pregnancy is common and is usually not a sign of a serious underlying health issue. The primary causes of heartburn during pregnancy include hormonal fluctuations and the expanding uterus, which puts pressure on the stomach and loosens the lower oesophageal sphincter (LES), leading to stomach acid refluxing into the oesophagus.Though heartburn is generally harmless, it may occasionally indicate gastroesophageal reflux disorder (GERD) if it occurs regularly or severely. GERD may need further medical attention and treatment to control symptoms effectively.
In general, heartburn is just a sign of the body’s adjustment to pregnancy and can be managed through nutritional changes, lifestyle shifts, and safe medication. It is essential to consult a healthcare professional about persistent or intense heartburn to exclude complications.
How to relieve heartburn in pregnancy naturally?
Heartburn is common during pregnancy due to hormonal changes and the growing baby putting pressure on your stomach. Here are some natural ways to relieve heartburn:1. Dietary changes
- Aim for smaller portion sizes and eat to comfortable fullness.
- Avoid foods that upset your stomach. Some common ones are spicy foods, fatty foods, fried items, chocolate, and sugar-sweetened beverages.
- Avoid lying down immediately after meals.
- Eat slowly.
2. Natural Remedies
- Drinking cold milk may ease the burning sensation.
- Eating a banana or oatmeal is easy on the stomach and can help soak up acid.
- Ginger tea may assist digestion and help with nausea.
- A spoonful of yogurt can also help balance stomach acid.
What helps heartburn in pregnancy – lifestyle changes
Heartburn during pregnancy is a common discomfort caused by hormonal changes and the growing baby putting pressure on the stomach. Simple lifestyle adjustments can help prevent and relieve symptoms without the need for medication: Eat smaller, more frequent meals: Having smaller meals more often can help stop acid reflux since big meals can pressure your stomach.- Avoid lying down immediately after meals.
- Sleep with your upper body elevated: Using extra pillows or a wedge pillow when you sleep can help prevent acid from rising, giving you some relief.
- Wear loose, comfortable clothing. Tight clothes around your waist can worsen heartburn by increasing stomach pressure. Choose loose, comfortable outfits instead.
- Avoid eating close to bedtime: It’s a good idea to avoid eating right before bed. Ensure your last meal or snack is at least two to three hours before going to bed to help with digestion.
- Practice gentle movement after meals. Light activities, like taking a short walk, after eating can help your digestion and ease acid reflux symptoms.
- Maintain good posture while sitting: Sitting up straight can relieve pressure on your stomach and keep acid from rising, which is a smart way to handle heartburn.
