Until now, only the small muscles in the immediate vicinity of the rectum are engaged with any effectiveness during the bowel movement. In cases of constipation or bowel slowness, doctors recommend changes in diet (eat more fiber), fluids (drink more water) and exercise (get more movement). In more severe cases, laxatives, injections and enemas may also be prescribed, none of which are overwhelmingly popular with the user.

The PUDU Stick changes all that by enabling the user to engage their primary abdominal muscles in support of small muscle activity at the rectum. By pulling on the handle, the upward force exerted is leveraged across the arms to contract the primary abdominal muscles, providing additional downward compression on the lower abdomen. This helps the small muscles at the rectum, simplifying and speeding the bowel movement.
