Pregnancy and Heartburn: Causes, Prevention, and Relief
Comprehensive guide to understanding, preventing, and relieving heartburn during pregnancy for a healthier experience.
Pregnancy and Heartburn
Heartburn, a burning sensation often felt in the chest or throat, is a common ailment experienced during pregnancy. Affecting as many as half of all expectant mothers, heartburn can occur at any stage but tends to worsen as pregnancy progresses. Understanding the underlying causes, recognizing symptoms, and knowing safe and effective ways to manage heartburn are essential for maintaining comfort and maternal well-being.
What is Heartburn?
Heartburn, medically referred to as gastroesophageal reflux, is the result of stomach acid flowing back into the esophagus. The main symptom is a burning pain below the breastbone, which can radiate to the throat, accompanied by a sour or bitter taste in the mouth. During pregnancy, heartburn can be persistent and troublesome, but it seldom poses a risk to the mother or the baby.
Why is Heartburn Common During Pregnancy?
Heartburn’s prevalence in pregnancy is due to several physiological changes and external pressures:
- Hormonal Changes: Increased levels of progesterone relax the lower esophageal sphincter (LES), the valve separating the stomach and esophagus. When the LES is relaxed, stomach acid is more likely to escape into the esophagus.
- Growth of the Uterus: As the pregnancy progresses, the expanding uterus exerts increasing pressure on the stomach, especially in the third trimester. This mechanical pressure pushes stomach contents upward, contributing to reflux.
- Slowed Digestion: Pregnancy hormones slow the movement of food through the digestive tract, resulting in increased chances of heartburn.
These factors combine, making heartburn a frequent complaint from early weeks to the final trimester.
Common Symptoms of Heartburn During Pregnancy
- Burning sensation in the center of the chest, especially after eating
- Sour or bitter taste at the back of the throat or mouth
- Regurgitation of food or fluids
- Persistent cough or sore throat
- Difficulty swallowing
These symptoms can range from mild discomfort to significant pain, often intensifying when lying down or immediately after a meal.
When Does Heartburn Start and How Common Is It?
| Trimester | Prevalence of Heartburn |
|---|---|
| First Trimester | 26% |
| Second Trimester | 36% |
| Third Trimester | 51% |
Unlike typical heartburn rates in adults (about 20%), heartburn in pregnancy progressively intensifies towards the third trimester, due to rising hormones and anatomical changes.
What Causes Heartburn During Pregnancy?
Several factors contribute to the development of heartburn during pregnancy:
- Hormonal shifts: Elevated progesterone and estrogen relax the LES and slow digestion.
- Growing uterus: Increased abdominal pressure displaces the stomach upward.
- Dietary habits: Consumption of foods that trigger acid production aggravates symptoms.
- Eating patterns: Large meals, eating late, and lying down after eating are common triggers.
Identifying Common Heartburn Triggers
Pregnant women may notice that heartburn is aggravated by certain foods and lifestyle habits. Common triggers include:
- Spicy foods
- Fatty or fried foods
- Citrus fruits and juices (orange, lemon, grapefruit)
- Tomatoes and tomato-based products
- Chocolate
- Mint (including candies and teas)
- Carbonated beverages (sodas)
- Alcohol (should be avoided in pregnancy for multiple reasons)
- Caffeinated products

Prevention Strategies: How To Reduce Heartburn in Pregnancy
Dietary Modifications
- Avoid Trigger Foods: Steer clear of spicy, fatty, citrus, chocolate, and tomato-based products.
- Smaller, Frequent Meals: Eating less at each meal, but more frequently, keeps the stomach from filling up and reduces pressure that causes reflux.
- Eat Slowly: Chew food carefully and avoid eating quickly. This helps prevent both swallowed air and overfilling the stomach.
- Time Your Last Meal: Finish eating at least three hours before bedtime to allow digestion before lying down.
- Stay Upright After Eating: Sitting or standing after eating helps prevent acid backflow.
Lifestyle Adjustments
- Avoid Tight Clothing: Snug clothes, including belts and waistbands, can increase abdominal pressure and trigger heartburn. Choose loose, comfortable outfits.
- Elevate Your Head: While resting or sleeping, use wedge pillows or raise the head of the bed by 6–8 inches. This helps gravity keep acid in the stomach where it belongs.
- Avoid Tobacco and Alcohol: These substances relax the LES and worsen reflux. Both should be completely avoided during pregnancy.
- Gentle Exercise: Moderate physical activity supports digestion, but vigorous movement after eating can worsen symptoms.
Bending and Sleeping
- Avoid Bending Over: When possible, squat with knees instead of bending at the waist, especially after meals.
- Sleep on Your Left Side: This position may decrease the likelihood of reflux compared to sleeping on your right side or back.
Safe Home Remedies for Pregnancy Heartburn
When prevention strategies aren’t enough, some natural remedies and modest dietary changes may offer relief:
- Yogurt: The probiotics and cool texture can soothe acid irritation and help neutralize stomach acid.
- Warm Milk with Honey: Combining milk and honey acts as a gentle buffer against stomach acid, helping neutralize it.
- Almonds: A handful of almonds may soothe heartburn by lowering acidity.
- Pineapple and Papaya: The enzymes found in these fruits aid digestion and can help mitigate reflux after meals.
- Ginger: Moderate amounts (as tea or chews) may calm stomach irritation, though excess consumption should be avoided.
- Peppermint: Peppermint tea or sugar-free peppermint candies may relieve symptoms for some, but it can worsen heartburn for others; monitor your reaction.
- Lemon Water: Sipping lemon water can support the production of digestive juices.
- Apple Cider Vinegar: Dilute one teaspoon in an 8-ounce glass of water; some find this balances stomach acid.
While these remedies are generally safe, consult your healthcare provider before trying anything new, especially supplements or herbs.
Medical Options and When to Consult Your Physician
Most cases of heartburn during pregnancy are manageable with lifestyle and dietary measures. However, sometimes symptoms are severe, frequent, or unresponsive to self-care. In such cases:
- Schedule an appointment with your obstetrician or primary care provider to discuss symptoms.
- Ask about pregnancy-safe medications: Antacids containing calcium carbonate (such as Tums) are generally regarded as safe. Avoid antacids with sodium bicarbonate or magnesium trisilicate unless advised by your doctor.
- Avoid over-the-counter medications like Pepto-Bismol, as some are not recommended for use in pregnancy.
- If symptoms accompanied by vomiting, severe pain, difficulty swallowing, or weight loss, seek medical attention immediately.
How to Get Rid of Heartburn During Pregnancy Quickly
If you’re experiencing heartburn and want rapid relief, try these steps:
- Eat a small amount of yogurt or drink warm milk mixed with honey.
- Sip water throughout the day; do not gulp large amounts at once.
- Chew on a few raw almonds or fresh papaya post-meal.
- Walk gently after meals to stimulate digestion.
- Elevate your upper body when resting.
Remember, improvement may be gradual, and not every remedy works for every person. Consult your healthcare provider for ongoing or intense discomfort.
Heartburn Myths and Facts in Pregnancy
- Myth: Heartburn harms the baby.
Fact: Heartburn may cause discomfort, but does not affect the baby’s health. - Myth: Spicy food always causes heartburn.
Fact: While it is a common trigger, not every woman is affected. Monitor your personal reactions. - Myth: Only large meals trigger it.
Fact: Even small snacks can induce heartburn depending on content and timing. - Myth: Heartburn predicts a hairy baby.
Fact: Some studies suggest a link between moderate heartburn and infant hair growth, but this is not conclusive.
Is Heartburn Dangerous During Pregnancy?
Heartburn is uncomfortable but rarely dangerous for mother or child. However, chronic heartburn can affect sleep and nutrient absorption. Severe cases may indicate more serious conditions such as gastroesophageal reflux disease (GERD) or pregnancy complications. Always report persistent or unusual symptoms to your provider.
