Dear student,
Without proper functioning of the bowels, waste can be trapped for days, weeks, months, or even years. Un-eliminated waste can cause toxins to back up in the colon, which sets an environment for auto-intoxication -- self-poisoning. In this case, the bowel walls become encrusted with un-eliminated fecal matter, hampering the absorption of vital nutrients and providing a breeding ground for unhealthy bacteria. Blood capillaries lining the bowel wall begin to absorb these toxins into the bloodstream, consequently polluting all of our organs and cells.
