There are several methods people use to remove old feces from the colon, though most health experts agree that the body naturally eliminates waste effectively and does not require external cleansing except in specific medical cases[2].
Colon cleansing methods include:
- Use of laxatives and supplements: Both stimulant and non-stimulant laxatives, as well as powdered or liquid supplements, are used to help expel colon contents[1]. Polyethylene glycol (PEG) solutions are frequently prescribed for medical bowel preparation prior to procedures like colonoscopy[3].
- Enemas: This involves introducing a small amount of liquid into the rectum, which helps empty the lower part of the colon[2]. Enemas are sometimes used to relieve constipation or prior to certain medical exams.
- Colonic irrigation (high-volume colonic cleanse): A professional procedure where large amounts of water (sometimes 16 liters or more) are flushed through the colon. An inserted tube allows water in and waste out, sometimes with added substances like enzymes, probiotics, or herbs[1][4]
- Staying hydrated: Drinking adequate water daily helps keep stool soft and promotes normal bowel movements. Aim for six to eight glasses of water daily to naturally support colon health and waste elimination[5].
While these methods exist, the medical consensus is that routine colon cleansing is generally unnecessary for healthy individuals. The colon and digestive system naturally remove waste and bacteria from the body without intervention[2][7]. Most evidence supporting at-home or professional colon cleanses is anecdotal or based on alternative health beliefs, and risks—including dehydration, infections, and injury—are possible if cleansing is done improperly[6].
If you are experiencing chronic constipation or believe you have a buildup of old feces, it is recommended to consult a healthcare provider before attempting any colon cleansing regimen[1]. They can recommend safe, effective treatments or diagnose any underlying issues.
