Heartburn in Pregnancy | Causes and Relief of Indigestion and Heartburn During Pregnancy

Many pregnant women experience heartburn during pregnancy, particularly as their pregnancy progresses. Although it is often called heartburn, the discomfort is actually related to indigestion and acid reflux caused by stomach acid moving into the oesophagus.

This burning sensation in the chest or throat can feel uncomfortable, especially after eating or when lying down. While heartburn can occur at any stage, it often becomes more noticeable during the second and third trimester.

Understanding the causes of heartburn in pregnancy, recognising symptoms, and learning safe ways to manage indigestion can help pregnant women stay more comfortable throughout pregnancy.

If you are navigating common pregnancy symptoms, you can explore helpful guidance through the Parenting Hub's free tools, which provide support for many pregnancy and parenting concerns.

 

Why Heartburn Happens During Pregnancy

Heartburn occurs when stomach acid flows back into the oesophagus, the tube that connects the mouth to the stomach. This is often referred to as acid reflux or gastroesophageal reflux.

During pregnancy, several changes in the body can increase the likelihood of heartburn, including the pregnancy hormones.

One major factor is the hormone progesterone, which relaxes muscles throughout the body. This includes the sphincter muscle, which normally prevents stomach acid from moving back into the oesophagus.

As pregnancy progresses, the growing uterus also places pressure on the stomach. This pressure can push stomach acid upward, causing the familiar burning sensation of heartburn.

These changes make heartburn and indigestion common during pregnancy, especially in the later stages.

 

Common Symptoms of Heartburn

The symptoms of heartburn during pregnancy can vary from mild to more persistent discomfort.

Common symptoms include:

• A burning sensation in the chest or throat
• Sour or acidic taste in the mouth
• Discomfort after eating
• Pain that worsens when lying down
• Feeling of food coming back up

Some women may also experience symptoms related to gastroesophageal reflux disease (GERD) if reflux becomes frequent.

Although heartburn can occur during the first trimester, many women notice symptoms worsening in the third trimester as the uterus continues to grow.

 

Foods That May Trigger Heartburn

Certain foods are more likely to trigger indigestion and heartburn during pregnancy.

Common trigger foods include:

• Spicy foods
• Fatty foods
• Fried foods
• Citrus fruits
• Acidic foods such as tomatoes
• Chocolate or caffeinated drinks

These foods may increase stomach acid production or relax the oesophageal sphincter, allowing acid to move upward.

Paying attention to foods that worsen symptoms can help pregnant women better manage heartburn.

 

Lifestyle Changes to Reduce Heartburn

Simple lifestyle changes can help relieve heartburn during pregnancy.

Helpful strategies include:

• Eating smaller meals throughout the day
• Avoid lying down immediately after eating
• Sitting upright during and after meals
• Avoiding large meals before bedtime

Many women find that eating smaller portions more frequently helps reduce pressure on the stomach and prevents reflux.

Avoiding heavy meals before going to bed may also help reduce nighttime symptoms.

 

Sleeping Positions That Help Reduce Reflux

Sleeping position can influence heartburn symptoms.

Raising the upper body slightly may help prevent tummy acid from flowing back into the oesophagus.

Many pregnant women find relief by:

• Using extra pillows
• Raising the head of the bed slightly
• Avoiding lying completely flat, elevate the head of your bed

These adjustments help gravity keep stomach acid in the stomach.

 

Medical Treatments for Pregnancy Heartburn

If lifestyle adjustments are not enough, healthcare professionals may recommend additional treatment options.

Some pregnant women may use antacids or medications recommended by their healthcare provider to help neutralise stomach acid.

However, pregnant women should always speak with a healthcare professional before taking medications during pregnancy.

A healthcare professional can determine the safest option for treating heartburn and indigestion.

 

When Heartburn May Need Medical Advice

While heartburn is very common during pregnancy, severe or persistent symptoms may require medical attention.

Pregnant women should speak with their healthcare provider if:

• Heartburn becomes severe
• Symptoms occur daily
• Difficulty swallowing develops
• There is significant chest pain

In some cases, persistent reflux may be related to gastroesophageal reflux disease during pregnancy.

A healthcare provider can recommend treatment options to help manage symptoms safely.

Creating a Comfortable Evening Routine

Heartburn symptoms often worsen in the evening when lying down. Creating a relaxing bedtime routine may help reduce discomfort before sleep.

Helpful strategies include:

• Eating dinner earlier in the evening
• Avoiding trigger foods before bedtime
• Sitting upright after meals

Some pregnant women also find relaxation helpful before sleep. Gentle background sounds from Genie Lullaby may help create a calm environment for rest.

 

Final Thoughts – Heartburn in Pregnancy

Heartburn and indigestion during pregnancy are common experiences caused by hormonal changes and the growing uterus.

As pregnancy progresses, relaxed muscles and increased pressure on the stomach can allow stomach acid to move into the oesophagus, causing the familiar burning sensation.

Fortunately, many women find relief through simple lifestyle changes such as eating smaller meals, avoiding trigger foods, and adjusting sleeping positions.

If symptoms persist or become severe, speaking with a healthcare professional can help identify safe treatment options.
