The truth is, chest discomfort during pregnancy happens for many reasons and most likely it is not a serious concern.

In some women, it happens because of the chest compression by the growing baby. Your chest consists of different organs, including the heart and lungs. As your womb grows, it forces your diaphragm against your chest causing pain.

What causes chest pain during pregnancy?

Like already mentioned, chest pain happens due to physiological changes during pregnancy. Here are the reasons why they occur

1.  Effect of progesterone hormone

Immediately after getting pregnant, there is a progesterone surge. This hormone can cause changes to your lower esophageal splinter and result in Acid reflux.

The lower esophageal sphincter is at the inferior end of the esophagus, an 8 inches muscular tube that conveys food from your mouth to your stomach.

During pregnancy, progesterone relaxes the esophageal sphincter resulting in upward movement of stomach contents into the esophagus.

This can result in the irritation and inflammation of the esophagus resulting in a burning sensation (Heart pain) in the lower part of the chest and the upper abdomen.

Pregnant women will experience this type of chest pain at night, after eating or when lying down.

2.  Expanding chest wall

Another reason you may feel chest discomfort while pregnant is the pressure effect of your baby against the thoracic cavity.

Between your chest wall and abdomen is the diaphragm. As your baby grows, it compresses on the diaphragm and chest wall reducing the chest ability to expand. This pain may be felt on both sides, center, or on the left or right side.

If you feel symptoms are getting worse, talk to your doctor for help.

3.  You are stressed up

It is normal for pregnant women to worry easily for the well being of their baby. if you get worked up emotionally or physically, it can have an impact on your health

If you already have these symptoms, it is likely you have a chest infection. So, see a doctor.

During pregnancy, it is more likely to develop a heart attack compared to non-pregnant women. However, the chances are slim. So, don’t panic. Only 1 in 16,000 women will develop a heart attack during pregnancy.

Therefore, if you have central chest pain while pregnant, it is most likely due to other causes rather than a heart attack. It best you see your doctor.

6. Asthmatic attack

Bronchial asthma is a long-term condition that causes chest tightness, pain, and difficulty in breathing.

7.  Hypertension complication (preeclampsia)

During pregnancy, it is possible to develop new-onset high blood pressure after the 20th week. This results from placental changes and its more likely to occur in first-time moms, twin pregnancies, and women who get pregnant after 40 years.

In severe cases of high blood pressure in pregnancy, you may experience chest pain due to the accumulation of fluid in your chest.
