Can severe abdominal bloating be caused by a hiatal hernia.. much worse @ night. haven't slept much in weeks! already been diagnosed with the hernia.

Abdominal pain: This could be related to your gallbladder, gerd, irritable bowel or other GI issues. Less commonly you could have a twist in the stomach related to your hernia depending on the type or if its paraesophageal you should start with an appointment at your pcp and then have imaging performed and or see a GI physician or surgeon.

Yes: A hiatal hernia is a widening of the space where the esophagus goes through the diaphragm between the chest and the abdomen. The hernia comes about when the stomach slips through this space. As the stomach fills while eating or drinking it stretches the stomach and the portion that is in the chest can't stretch much, therefore you feel bloated.
