Why do ‘high volume enemas’ always consist of only higher volumes of fluid, and not inserting the tube higher up the colon?

It’s done for colonics and the entire human colon is just over 4 ft. long, so why do they say to insert the enema tube only 2-4 inches?

There are a couple of good reasons to avoid inserting an enema tube too far. First is the danger of physical damage to the colon. The colon's lining is delicate and highly vascularized; inserting anything into this area of the body risks injury or even perforation, which can lead to peritonitis, a serious and potentially life-threatening condition.

Additionally, inserting an enema tube -or anything else- more than a few inches creates the risk of stimulating the vagus nerve,  which can result in a heart arrythmia such as bradycardia, possibly leading to cardiac arrest.

Because of these risks, colonics should always be performed by a qualified individual, and should only be done if there is a medical need.
