What is an Epigastric Hernia?
An epigastric hernia develops along the linea alba, the fibrous band in the center of the abdomen, specifically in the area between the belly button (umbilicus) and the breastbone (xiphoid process).
The linea alba is formed by the joining of the abdominal muscle sheaths at the midline. Small defects can allow fat from inside the abdomen to protrude, creating a visible or palpable bulge.
Key Characteristics
Midline Location
Located specifically in the upper midline between the belly button and the breastbone.
Often Small
Typically small defects containing preperitoneal fat, though they can occasionally enlarge.
Gender Bias
Epigastric hernias are about three times more common in men than in women.
Congenital Factor
Often present at birth due to a weakness or opening in the fibrous linea alba.
Triggered by Strain
The bulge may appear or become more prominent during physical exertion, coughing, heavy lifting, or straining.
