What Is Heartburn During Pregnancy?

Heartburn is a burning sensation that extends from the bottom of the breastbone to the lower throat. Acid reflux or gastroesophageal reflux causes heartburn.

The fluctuating physical and hormonal changes in your pregnancy are also a major cause for the condition. The hormones slow down the functioning of the lower esophageal sphincter, causing relaxation of the muscle and heartburn or acid reflux during pregnancy (1).

Women who have late pregnancies are more prone to the problem than those who become mothers at an early age.

Heartburn worsens under the following situations:

  • If there is more than one baby in your womb.
  • If your baby is big in size.
  • If your baby is in breech position in the womb.

Is Heartburn An Early Sign Of Pregnancy?

Yes, heartburn could be an early sign of pregnancy. You will start experiencing it before your missed period.

However, heartburn alone doesn’t point to pregnancy as it is caused due to several other reasons such as eating spicy food or having acid reflux. It indicates pregnancy only if you are having other symptoms too.

Heartburn accompanied with acid reflux will begin in the initial few weeks of your pregnancy and will worsen in your third trimester (2).

What Causes Heartburn During Pregnancy?

Acid reflux occurs when the contents of your stomach flow back through the esophageal tube. The junction where the esophagus joins the stomach is called the cardiac sphincter. This cardiac sphincter must function correctly to stop this flow and keep the food in your belly.

1. Improper working of the cardiac sphincter:

If the cardiac sphincter does not work properly or becomes weak owing to your pregnancy, then it can lead to heartburn. This would cause the contents of your stomach to reach the esophagus. Certain enzymes and hormones secreted during your pregnancy cause this flow.

2. Hiatus hernia:

Heartburn can be a result of the condition called hiatus hernia. A hiatus hernia is caused when a part of your stomach pushes into the hiatus (an opening in the diaphragm) as your baby gets bigger (3). This blocks the food pipe, causing heartburn.

3. Infection due to H. pylori:

Helicobacter pylori is a type of bacteria that is capable of causing problems in your stomach and intestine (4). The presence of this bacterium in the mucus membrane of your stomach can cause bloating, burping, pain and even stomach ulcers, leading to heartburn.

4. Gastritis:

The chronic inflammation of your protective stomach lining is called gastritis. If you experience gastritis during pregnancy, this can lead to severe heartburn.

6. Other causes of heartburn:

Carrying multiple babies is one more reason for undue pressure on the sphincter, resulting in heartburn. There are a few more lifestyle causes for the condition:

  • Overweight or obesity
  • Smoking
  • Eating oily and spicy food
  • Excessive consumption of alcohol or caffeine
  • Lying down or sleeping immediately after meals
  • Strong medications
  • Use of medicines like ibuprofen or aspirin

Most of the causes, other than the lifestyle choices, are majorly due to the pressure put by the expanding uterus on the sphincter. However, the food that you consume can also be the culprit.

Foods that Cause Heartburn During Pregnancy

From coffee and alcohol to tomatoes and grapefruit, some foods are known to trigger heartburn:

1. Spicy foods:

Sweet or hot peppers, Mexican food, and other spices are inflammatory in nature. They create more acids, resulting in heartburn. Avoid such foods completely or take them in small amounts.

2. Alcohol:

Alcoholic beverages such as wine, beer, and spirits relax the sphincter muscle, which creates an opening. The food in the stomach comes back from the opening. Alcohol also increases the production of acid in the stomach.

3. Fatty foods:

High-fat foods such as cheese, nuts, and red meat can stimulate heartburn as fatty foods slow down the digestion process. The stomach generates more acids to complete the digestion, thus resulting in heartburn.

4. Carbonated drinks:

Gas present in the carbonated drinks or sparkling water gets trapped in your tummy, thereby, creating pressure. This causes the acids to travel back into the esophagus.

5. Citrus fruits:

They contain acids, which make the heartburn worse especially when taken on an empty stomach. Grapefruit, tomatoes, and oranges are some fruits which you need to stop eating to avoid heartburn.

6. Caffeine:

Like alcohol, high amount of caffeine also relaxes the sphincter, creating an opening through which the food can escape and lead to heartburn. Therefore, have coffee, tea and other caffeinated beverages in small portions.

7. Garlic and onion:

Garlic and onion, like the other root vegetables, increase the gastric acids. They also slow down the stomach from emptying its content, causing reflux. Dried or dehydrated forms of these foods are better than the fresh or raw ones.

8. Peppermint:

Peppermint is soothing for the stomach but triggers heartburn. Avoid taking after-meal mint as it can worsen heartburn. It relaxes the sphincter muscle, thus allowing the stomach acids to travel back into the esophagus.

9. Chocolate:

Chocolate has caffeine and, so, causes heartburn. It also contains other heartburn stimulants such as theobromine. Too much chocolate can make the sphincter to relax.

If you think you have consumed a little too much of the above foods, or in general, you suspect heartburn, look for its symptoms.

Self-Help Measures To Manage Heartburn During Pregnancy

When the heartburn is severe, you need to see a doctor immediately. However, if it is mild, follow these self-help tips for relief:

The major triggers for heartburn are eating, bending over and lying down. Minimize these to mitigate heartburn.

  1. Choose easy-to-digest foods and drinks. Stay away from highly fatty or spicy foods, citrus fruits, chocolates, alcohol, coffee and the other foods mentioned above.
  1. Eat often in small portions as it restricts the stomach from generating excessive acids (5).
  1. Stop smoking as it relaxes the valve between the stomach and esophagus, causing acid reflux. It can also be harmful to the fetus.
  1. Slumping posture can be harmful. Bending or leaning can make the symptoms worse. Sit straight and remain upright for at least one-hour after eating.
  1. Avoid eating or drinking just before bedtime. Heartburn can be worse in the night. Have a gap of three hours between your supper and sleep.
  1. Sleep propped up. Keep some cushions to raise your head or some sturdy objects under the head-end of the bed. Gravity works here by keeping the stomach acids in place and aids better digestion (6).
  1. Medications can also be risky. Some medications such as non-steroidal drugs and antidepressants can make the heartburn worse. You should check with your doctor if you have heartburn due to these medications.
  1. Chew gum after meals. It helps to stimulate the salivary glands as saliva neutralizes stomach acids (7).
  1. Wear comfortable and loose clothing. See to it that there is no tightening around your tummy and waist as it can increase the pressure and trigger heartburn.

Though you may not completely avoid heartburn through the above measures, they can provide your some relief.

Treatments For Heartburn

If your heartburn does not subside in spite of all your efforts, your doctor will suggest a few medications:

  1. Antacids such as Tums (8) are prescribed if the heartburn is strong. They neutralize your stomach acids.
  1. Alginates also provide relief from heartburn. They form a protective layer over the walls of your stomach and esophagus and provide relief against reflux.


  • Antacids will interfere with iron absorption if you take them without enough time gap. Schedule different timings for the two medications.
  • Certain antacids contain higher amounts of sodium, which stimulate fluid buildup in the body tissues. If it is severe, you should see your doctor immediately.


Heartburn is a fairly common pregnancy problem that usually occurs due to physical and hormonal fluctuations. However, lifestyle factors, such as eating oily and spicy food and gastrointestinal problems like gastritis, can also cause it.
