The short answer is no.
The amount of stool and digestive contents in the intestines varies from person to person. A person who is constipated may have stool accumulated in the colon, but the idea that everyone carries 15 kilograms of old waste that can simply be flushed out overnight is not supported by medical evidence.
Colon cleansing is also different from normal digestion. According to Mayo Clinic, the digestive system naturally removes waste from the body, and there is no good evidence that routine colon cleansing is necessary to remove so-called toxins. Some forms of aggressive colon cleansing can also cause dehydration, electrolyte problems, cramping, diarrhea, infection, or other complications.
So rather than looking for a powerful overnight “flush,” focus on helping your digestive system function normally.
What Does Constipation Actually Mean?
Constipation is more than simply not having a bowel movementevery day
According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), symptoms can include:
Having fewer than three bowel movements per week
Hard, dry, or lumpy stools
Pain or difficulty when passing stool
Feeling that you have not completely emptied your bowels
Abdominal discomfort or bloating
Not everyone has the same normal bowel pattern, so occasional differences do not necessarily mean something is wrong.
Constipation can be associated with not getting enough fiber, inadequate fluid intake, low physical activity, changes in routine, ignoring the urge to use the bathroom, certain medications, and some medical conditions.
