What Is Pregnancy Heartburn?
Heartburn, also known as acid reflux or gastroesophageal reflux, is a burning sensation in your chest that can extend up to your throat. Despite its name, heartburn has nothing to do with your heart. It occurs when stomach acid backs up into your esophagus, the tube that carries food from your mouth to your stomach.
During pregnancy, heartburn becomes extremely common due to both hormonal changes and the physical pressure of your growing baby. The burning feeling often gets worse after eating, when lying down, or when bending over.
Common Symptoms Include:
- •Burning sensation in the chest, especially after eating
- •Sour or bitter taste in the mouth
- •Difficulty swallowing or feeling of food stuck in throat
- •Regurgitation of food or sour liquid
- •Feeling bloated or uncomfortably full
What Causes Pregnancy Heartburn?
Several factors combine to make heartburn so common during pregnancy:
Progesterone Hormone
This pregnancy hormone relaxes the valve (lower esophageal sphincter) between your stomach and esophagus. When this valve relaxes, stomach acid can more easily flow backward into your esophagus.
Growing Uterus
As your baby grows, your expanding uterus puts pressure on your stomach, pushing acid upward. This is why heartburn often worsens in the third trimester.
Slower Digestion
Pregnancy hormones slow down your digestive system, meaning food stays in your stomach longer. This prolonged digestion gives more opportunity for reflux to occur.
Certain Foods and Habits
Spicy, fatty, or acidic foods, as well as eating large meals or lying down soon after eating, can trigger or worsen heartburn symptoms.
When Heartburn Typically Occurs
First Trimester
Some women experience early heartburn due to rising progesterone levels, though it is less common. Nausea may be a bigger concern during this time.
Second Trimester
Heartburn becomes more noticeable as your uterus begins to grow and press against your stomach. Many women first notice symptoms around weeks 20-24.
Third Trimester
This is when heartburn peaks for most women. Your baby is taking up significant space, pushing your stomach upward and making reflux more likely. Symptoms may improve slightly when the baby drops lower near delivery.
Good news: For most women, heartburn resolves quickly after delivery once hormone levels return to normal and the pressure on your stomach is relieved.
Relief Strategies and Home Remedies
🍽 Eating Habits
- ✓Eat smaller, more frequent meals instead of three large ones
- ✓Eat slowly and chew your food thoroughly
- ✓Avoid eating within 2-3 hours of bedtime
- ✓Stay upright for at least an hour after eating
- ✓Drink fluids between meals rather than with meals
🚫 Foods to Avoid
- ✗Spicy foods and hot peppers
- ✗Fatty, greasy, and fried foods
- ✗Citrus fruits and juices
- ✗Tomatoes and tomato-based products
- ✗Chocolate, caffeine, and carbonated beverages
Lifestyle Adjustments
- •Elevate your head while sleeping - Use extra pillows or raise the head of your bed 6-8 inches
- •Sleep on your left side - This position reduces acid reflux
- •Wear loose clothing - Tight clothes can increase pressure on your stomach
- •Chew gum after meals - Increases saliva production to neutralize acid
- •Try ginger tea or ginger candies - May help soothe the stomach
- •Drink milk or eat yogurt - Can temporarily coat and soothe the esophagus
Safe Medications During Pregnancy
Always consult your healthcare provider before taking any medication during pregnancy, even over-the-counter options.
Antacids (Generally Safe)
Calcium carbonate antacids like Tums or Rolaids are generally considered safe during pregnancy and provide quick relief. They also supply extra calcium. Avoid antacids containing aluminum or excessive sodium.
H2 Blockers
Medications like famotidine (Pepcid) may be recommended by your doctor if antacids are not providing enough relief. These reduce acid production.
Proton Pump Inhibitors (PPIs)
For severe cases, your doctor may prescribe a PPI like omeprazole (Prilosec). These should only be used under medical supervision during pregnancy.
When to Call Your Doctor
While heartburn is common and usually harmless, contact your healthcare provider if you experience:
- ⚠Heartburn that does not improve with over-the-counter remedies
- ⚠Difficulty swallowing or pain when swallowing
- ⚠Vomiting blood or material that looks like coffee grounds
- ⚠Severe stomach pain along with heartburn
