That claim is misleading and potentially dangerous. You cannot safely “clean 15 kilograms of waste from your colon in one night,” and your colon does not normally accumulate anything close to that amount of fecal waste.
What actually happens?
Your colon continuously moves stool toward the rectum. The amount of stool in the digestive tract varies with diet, hydration, bowel habits, and other factors. A large bowel movement after a laxative or bowel-preparation product doesn’t mean that kilograms of “toxins” or old waste have been removed.
Products marketed as overnight colon cleanses—especially strong laxatives, enemas, or herbal mixtures—can cause:
- Dehydration
- Loss of electrolytes such as potassium and sodium
- Abdominal cramps and diarrhea
- Dizziness or weakness
- Medication interactions
- In serious cases, kidney or heart complications
For ordinary constipation, safer approaches generally include adequate fluids, dietary fiber, regular physical activity, and appropriate treatment when needed. If constipation is persistent, severe, or accompanied by significant abdominal pain, vomiting, blood in the stool, or inability to pass gas, medical evaluation is important.
Bottom line: You don’t need to “detox” a healthy colon overnight. If this headline is promoting a particular recipe or drink, send me the ingredients and I can tell you whether it’s safe.
