Abdominal bloating can affect the diaphragm, a muscular partition between the chest and abdomen. The diaphragm assists in breathing, which means bloating can lead to shortness of breath. This happens if the pressure in the abdomen is enough to restrict the movement of the diaphragm. Being short of breath can cause you to take small, short breaths. This can lead to swallowing air, which is known as aerophagia. Difficulty breathing can be brought on by anxiety or panic attacks, chronic obstructive pulmonary disease (COPD), pneumonia, and asthma attacks.
