The claim “remove 10 pounds of waste from your colon in one night” is not supported by medical evidence and is a common marketing claim used to promote “colon cleanses” or detox products.
Here’s what you should know:
Your colon doesn’t normally store 10 pounds of waste
In healthy people, the colon continuously moves stool toward elimination. It is not designed to accumulate large amounts of old waste that need to be “cleaned out.”
“Colon cleanses” aren’t necessary for most people
The digestive system naturally removes waste. There is no evidence that routine colon cleanses:
- Remove toxins
- Improve overall health
- Cause lasting weight loss
Any rapid weight loss after a cleanse is usually due to loss of water and stool, not body fat.
Potential risks of colon cleansing
Some cleanses, laxatives, or enemas can cause:
- Dehydration
- Electrolyte imbalances
- Diarrhea
- Abdominal cramping
- Damage to the colon (in rare cases)
These risks are greater for older adults and people with kidney disease, heart disease, or inflammatory bowel conditions.
If you’re constipated
Safer, evidence-based approaches include:
- Drinking enough fluids.
- Eating more fiber (fruits, vegetables, whole grains, legumes), increasing it gradually.
- Getting regular physical activity.
- Responding promptly to the urge to have a bowel movement.
- Using an appropriate over-the-counter laxative if recommended by a healthcare professional
