They stick to the inside of the colon, particularly in the sacculated pouches or haustra , and are difficult for the colon to move through unless there is enough fiber present from other sources. This stagnant material provides a breeding ground for toxin-producing harmful bacteria. The blood is only as clean as the bowel. The blood absorbs toxins from the bowel and carries them to the liver to be detoxified. When the liver is overloaded because of a toxic colon, not only does it suffer, but the toxins are released into the general circulation where they can effect every cell in the body.
Antibiotics are drugs that are used to kill bacteria.
But they kill the good ones as well as the bad. Constipation is caused primarily by insufficient dietary fiber. Contributing factors are lack of exercise and not drinking enough water. Laxatives are not a good solution. They work by irritating the bowel in order to rid the colon of its contents by inducing a form of diarrhea.
