That burning sensation creeping up your chest after a meal is one of the most common complaints during pregnancy — and if you’re searching for how to get rid of heartburn during pregnancy, you’re far from alone. Studies suggest that more than half of all pregnant women experience it at some point, and for many, it becomes a daily struggle that affects sleep, appetite, and overall quality of life.
Why pregnancy and heartburn go hand in hand
The root cause isn’t mysterious. During pregnancy, the body produces elevated levels of progesterone, a hormone that relaxes smooth muscle tissue — including the lower esophageal sphincter, the valve that normally keeps stomach acid where it belongs. When this valve relaxes, acid flows upward, creating that familiar burning feeling in the chest or throat.
On top of that, as the uterus grows — especially in the second and third trimesters — it physically pushes against the stomach, increasing pressure and making acid reflux during pregnancy even more likely. So the discomfort tends to worsen as the pregnancy progresses, which can feel frustrating when you’re already dealing with so much else.
Adjusting what and how you eat makes a real difference
Food choices and eating habits have a direct impact on heartburn frequency and severity. Rather than overhauling your entire diet overnight, small targeted changes can bring noticeable relief relatively quickly.
- Eat smaller meals more frequently — a full stomach puts more pressure on the esophageal sphincter and increases the chances of reflux.
- Avoid lying down right after eating. Aim to stay upright for at least an hour after meals.
- Chew slowly and thoroughly. Rushed eating tends to introduce more air and increases digestive stress.
- Limit foods known to trigger acid reflux: spicy dishes, citrus fruits, tomato-based sauces, chocolate, fried or fatty foods, and carbonated drinks.
- Drink fluids between meals rather than with them, to avoid overfilling the stomach.
None of these changes require you to eat bland or joyless food. It’s more about timing and portion awareness than deprivation.
“Eating five smaller meals a day instead of three large ones is one of the most consistently recommended strategies by OB-GYNs for managing heartburn symptoms during pregnancy.”
Sleeping position and body posture matter more than you’d think
Nighttime heartburn is particularly disruptive because it can prevent restful sleep at a time when your body genuinely needs it. Elevating the head of your bed by about 15–20 centimeters — either with a wedge pillow designed for pregnancy or by propping up the mattress itself — helps use gravity to keep acid in the stomach where it belongs.
Sleeping on your left side is also associated with reduced reflux symptoms. This position keeps the stomach below the esophagus at a more favorable angle. It’s also generally recommended during pregnancy for optimal blood flow to the placenta, so it works on multiple levels.
| Sleeping position | Effect on heartburn |
|---|---|
| Left side with elevated head | Most effective for reducing nighttime reflux |
| Right side | May worsen symptoms due to stomach angle |
| Flat on back | Increases pressure and reflux risk, especially in later trimesters |
| Propped up with wedge pillow | Helpful addition when combined with left-side sleeping |
Safe remedies and when to consider medication
Some natural approaches to relieving pregnancy heartburn have good practical backing, even if large clinical trials are limited. A glass of cold milk or a small serving of plain yogurt can temporarily neutralize stomach acid for some women. Ginger — in the form of ginger tea or ginger chews — is widely used and generally considered safe in moderate amounts during pregnancy, and it may help with both nausea and digestive discomfort.
Almonds are sometimes mentioned as a natural antacid. While the evidence isn’t conclusive, they’re a nutritious snack regardless, so there’s little harm in trying a small handful when symptoms flare.
When lifestyle changes and natural remedies aren’t enough, there are antacids considered safe during pregnancy — particularly calcium carbonate-based ones like Tums. However, antacids containing sodium bicarbonate or aspirin should be avoided during pregnancy. Always speak with your healthcare provider before starting any medication, even over-the-counter products.
What to tell your doctor — and when to reach out sooner
Heartburn during pregnancy is common, but it’s not something you have to just endure in silence. If symptoms are severe, happen multiple times a day, or don’t respond to any of the strategies above, it’s worth raising this with your OB-GYN or midwife. In some cases, a prescription-strength medication such as an H2 blocker or a proton pump inhibitor may be appropriate and can safely be used under medical supervision.
There are also symptoms that should prompt you to contact your healthcare provider promptly rather than waiting for your next scheduled visit:
- Difficulty swallowing or pain when swallowing
- Vomiting blood or material that looks like coffee grounds
- Unexplained weight loss alongside heartburn symptoms
- Chest pain that feels different from typical heartburn and comes with shortness of breath
These are not signs of typical pregnancy heartburn and deserve prompt medical attention.
The good news that actually helps
For the vast majority of women, pregnancy-related heartburn resolves on its own after delivery — usually within days as hormone levels shift and the pressure on the stomach is relieved. Knowing this doesn’t make the discomfort less real in the moment, but it does offer a clear horizon. In the meantime, combining smart eating habits, thoughtful sleep positioning, and when necessary, safe medical support, gives you a practical toolkit that genuinely works. You don’t have to choose between managing symptoms and taking care of your pregnancy — both are possible at the same time.
