Does hiatle hernia cause stomach patrude?

No: A hiatal hernia affects the upper portion of the stomach responsible for keep stomach acid contained. There should be no visible signs of a hiatal hernia.

Nope.: The hiatus is the hole in the diaphragm thru which the esophagus passes to enter into the abdominal cavity; a hiatal hernia is an enlargement of this hole. It cannot be seen nor touched on physical examination. In contrast, a ventral hernia may cause the abdomen to protrude, as can a separation of the rectus muscles very common in men who are "round"in the midsection: this is called diastasis.
