Shortness of breath in pregnancy and frequent burping?

Common: Common during pregnancy. You need more oxygen during pregnancy and the body adapts to this. Also as the growing baby/uterus pushes against your diaphragm (muscle of breathing) your breathing might feel more labored. Burping occurs because the hormones in your body relax the muscles of the GI tract, causing more gas and bloating resulting in frequent burping. Both reverse after delivery.
