If you’re referring to the viral claim “Learn how to clean 15 kilograms of waste from your colon in one night,” that is not medically credible.
🚫 Your colon does not normally contain 15 kg of “waste”
There is no good evidence that ordinary people accumulate 15 kg of toxic waste in their colon or need to “detox” it overnight. Your digestive system continuously moves stool through the bowel, while your liver and kidneys handle many of the body’s waste products. Mayo Clinic says colon cleansing for “detoxing” is not necessary or recommended for any medical condition.

⚠️ What these “overnight cleanses” usually do
They commonly involve strong laxatives, enemas, herbal mixtures, or large amounts of fluids. These can cause:
Severe diarrhea and cramping
Dehydration
Dangerous electrolyte disturbances
Kidney problems
Bleeding or, rarely, bowel perforation
The risks are greater if you have kidney or heart disease, gastrointestinal disease, or have had colon surgery.

If you’re actually constipated
A safer approach is usually adequate fluids, gradual dietary fiber, regular physical activity, and—when appropriate—a properly selected laxative discussed with a pharmacist or doctor.
Medical bowel-cleansing preparations do exist, but they’re specifically used before procedures such as colonoscopy and should be taken according to medical instructions—not as a routine “detox.”

Bottom line: You don’t need to remove “15 kg of waste” from your colon overnight. If you’re experiencing persistent constipation, abdominal swelling, vomiting, severe abdominal pain, blood in the stool, or inability to pass stool/gas, get medical advice rather than attempting a detox.
