Shortness of Breath In Pregnancy

Mild persistent shortness of breath is very common during pregnancy. But it is important to think about other possibilities. Most of these problems are uncommon:

 

- Heart problems, such as an abnormal heart valve or impaired heart muscle contractions

- Blood clots in the lung's blood vessels (pulmonary embolism)

- Fluid in or around the lungs (pleural effusion)

- Very low red blood cell count (severe anemia). The mild anemia that often occurs during pregnancy does not usually cause significant shortness of breath.

- Weak diaphragm and chest wall muscles that can't pull enough air into the lungs (muscle or nerve diseases)

 

Now let's see if any of the conditions listed above might be causing your shortness of breath.
