Hernia represents a protrusion of an internal part of the body (organ or tissue) through a weakness in the muscular wall or in the surrounding tissue. The most common hernias are in the abdomen.

Also the weakness of the membranes or muscular wall could be involved like in poor nutrition, losing weight, scars, or posttraumatic situations.
Study of thoraco-abdominal diaphragm reveals a volume reduction of the diaphragmatic muscle fibers with vasodilatation, perivascular inflammation, and an increase of interstitial space which appears edematous with hemorrhagias, especially in the crura muscular portion. Quantitative analysis suggests loss of elasticity and reduced functional...
