But we have examined hundreds of ruptures under the searching X-rays.

And we long ago found that rupture is not a break or tear; something all physicians and surgeons now concede.

The muscles at some point have simply lost their strength—lost their elasticity—like a piece of old rubber which has lost its "stretch."

The Cause Of The Weakness

Sometimes this weakening is due to general poor health; sometimes to lack of exercise; and sometimes the weakness is inherited.

Now the bowels are always pushing or pressing more or less against the abdominal wall—any one, whether ruptured or not, can plainly feel that pressure when coughing or sneezing; while lifting or other exertion greatly increases the pressure or strain.

When in a healthy or sound condition, the abdominal wall is elastic; and when the bowels push against it, the muscles which form it simply stretch until the strain on them is over.

Just as when you pull at your cheek, the flesh falls back in position the instant you let go.

Why The Muscles Give Way Under Strain

But if the muscles of the abdomen are in a weak condition, they can't stand much strain—can no longer stretch—any quick movement is often enough to cause them to spread apart, forming an opening through which a part of the bowels pushes out or protrudes.
