Stool Transit, Colonic Muscular Actions & Regularity

About Stool Transit

Stool transit is influenced by colonic muscular actions, the colon lining, fiber intake, fluid intake, exercise, health and wellness (or illness). Fruit-Eze™ Regularity Blend provides the necessary materials to promote stool transit and regularity.

Stool transit time (or speed) affects stool quality. The amount of time it takes for stool to travel through the colon when the colon is functioning normally is called "Speedy Stool Transit". When stool transit is “speedy” just the right amount of fluid is extracted and stool quality is optimized. When transit is slow, stools dry out and harden because the colon continues to extract fluids from the prepared stools. When transit is too fast, stools are loosely formed because not enough fluid is absorbed.

Laxative Use Weakens Colon Muscles

The purgative action of stimulant laxatives interferes with normal colonic muscular actions. This interference weakens colon muscles. Fruit-Eze™ Regularity Blend is an alternative to laxatives that improves stool texture and provides a flexible material that strengthens and tones intestinal muscles.

Healthy Colon Muscle Tissue

The Colon is a Muscular Tube

The colon is a muscular tube surrounded by muscles. On the exterior, a band of three muscles run the length of the colon extending and retracting like a rubber band. Contractions of these muscles form haustra (pillow like pouches that hold waste as it is being processed). On the interior, muscles wrap around the colon in circular bands that expand and contract the colon wall in an action that is similar to opening and closing a fist.



Six Colonic Muscular Actions in the Colon

Six muscular actions play a part in fluid absorption, particle cohesion, stool formation, stool transit, and stool passage (defecation). If these muscles become weak, stool transit is slowed. The result is constipation. These six actions include:

  • Haustral Churning: Haustra distend - filling up with waste, then contract - passing the waste along to the next haustrum. This action facilitates fluid absorption and particle cohesion.
  • Peristalsis: Contractions in the interior and the exterior muscles produce a wave like motion to move waste along the length of the colon. As this action occurs, stools gradually take form and solidify.
  • Mass Peristaltic Reflex: Sensing the presence of food in the stomach, pressure sensitive nerves located in the middle of the transverse colon trigger the mass peristaltic reflex which drives stools into the sigmoid colon and the rectum.
  • Defecation Reflex: As stools move into the rectal sac and expand the rectal wall, pressure sensitive nerves in the rectum signal the brain which, in turn, triggers the defecation reflex. This reflex is the alert-signal to the body that it is time to “move” the bowel.
  • Anal Sphincter Reflex: Interior and exterior circular bands of muscles located in the anal wall, keep the rectum closed except during defecation when they expand - and reflexively close to permit stool passage.
  • Engagement of Abdominal Muscles: Defecation is aided by the voluntary and cooperative engagement of abdominal muscles in bearing down gently* to push stools out of the rectum as stools are being passed.
    * Avoid straining hard against stools during defecation.
