I saw an advertisement on TV claiming that there can be faeces residue attached to the inner surface of the large intestine, if the residue is not cleaned out using their products, it can cause health issues. How true is the claim?
user
It is entirely normal for some amount of faeces to remain in the gastrointestinal tract. Colon cleansing has not been shown to be beneficial, and some products meant to assist in it can in fact be harmful depending on their ingredients. However, it is possible for fecal matter to build up enough to cause freqeunt constipation, in which case you should consult your healthcare provider.

So it's not going to help me if I do colon cleansing, then?
user
If you are really worried about this, you can try some fasting and drinking water. Fasting should reduce faeces build up and water should help clean any residue. Otherwise a specific product won't help much more. In any case you choose, please consult your doctor first, no answer as good as it seems is free of risks.
