Colon Cleansing vs. Laxatives: Understanding the Differences

Colon cleanses and laxatives are ways to empty the bowels, but are quite different in practice. Both should be administered only after discussion with a health-care professional.

Colon Cleanse

• Colon cleansing involves irrigating the bowel with tap water, mineral water, coffee or other substances. The purpose is usually to clear toxins from the digestive tract.

Laxative

• Oral and rectal-suppository laxatives can be taken to help bowel movements occur. Types of oral laxatives include bulk formers (make bowels bulkier), hyperosmotics (make bowels more watery), lubricants, stimulants and stool softeners. Laxatives are for short-term use only.

Availability

• Laxatives are available without a prescription. Colon cleansing can be done at home, but is risky. Use of a licensed colon cleansing practitioner is recommended, according to the Mayo Clinic.

Risks

• The biggest risk of both colon cleanses and laxatives is dehydration. If you use either, be sure to drink plenty of fluids. Colon-cleansing risks include bowel perforation and electrolyte imbalances.

Contraindications

• People with heart or kidney disease are at higher risk for electrolyte imbalance with both colon cleansing and laxatives because of the possible use of sodium phosphate.
