If you've been tempted by promotions for "colon hydrotherapy"—that is, sessions in which you would pay someone to put a tube up your rectum and wash out your large intestine with water, like a dirty garage being hosed down in summer—then you've already overcome some impressive mental hurdles. Maybe you're almost ready to enjoy the relaxation, renewed energy, and improved health that the procedure promises. Before you take the plunge, as it were, here are a few points to consider.
It's not the 19th century.
People who offer colon hydrotherapy (also called a colonic) tell you the large intestine is full of "toxic waste and toxins." It does, of course, carry waste out of your body. But is it a two-way street?
"Intestinal autointoxication," the idea that poisons from your feces can move backward from your colon into the rest of your body, is an old one. Old as in ancient Egyptian. The Greeks were into it too, including Hippocrates and Galen.
In the 19th century, doctors prescribed laxative pills and enemas to cure all manner of illnesses. One man created and promoted a popular device called the Cascade. As alternative medicine researcher Edzard Ernst describes it, this was a rubber bottle with a nozzle for a person to insert into his or her rectum. When the person then sat on the bottle, it squirted 5 liters of fluid into up into the colon.
By the 1920s, though, some actual scientific study had been done on the subject. Unlike the Cascade, the theory of intestinal autointoxication did not hold water.
A toilet is not a gym.
"Having colonics is like taking your colon to the gym," declares the website for one colon hydrotherapy center. Filling the colon up with water and emptying it again, the theory goes, "exercises" the intestinal muscle so it can do its job better in the future.
"Injecting water into the colon will cause the colon to swell, and cause so-called 'stretch-activated' contractions of the smooth muscle surrounding the intestine," says Williams College physiologist Steven Swoap. These contractions are called peristalsis. "But the colon does this naturally as food stuffs pass through," he adds. "There is definitely no need to help this along for peristalsis to occur."
Colorectal surgeon Francis Seow-Choen points out in a review paper that since the colon is lined with smooth muscle (a type we can't voluntarily control), it cannot be toned like the muscles you work at the gym. Toned muscles are ones that we've consciously flexed so often, our brains learn to flex them automatically. Sit-ups work; water up the rectum doesn't.
It's rude to firehose your friends.
In addition to waste, your colon houses a large portion of your body's friendly bacteria. These gut microbes manufacture several vitamins we need, and seem to be involved in defending us from dangerous microorganisms and generally keeping us healthy.
One study found that cleaning the colon to prepare patients for a colonoscopy—in this case with a straightforward laxative, not with large volumes of pumped-in fluid as in a colonic—immediately altered the types of bacteria in patients' intestines. Another study found that cleaning out the colon both knocked down the bacterial population there and seemed to make it easier for new, potentially unfriendly bacterial strains to move in.
It might kill you.
"My biggest worry would be perforations caused by the water," Swoap says. "If abrasions or tears in the colon occur, you have the possibility of a dangerous bacterial infection." Ironically, one way to make the material in your colon as dangerous as colonic practitioners claim is to blast it with water. Breaking up the feces and creating tiny tears in the colon can turn a one-way street into a two-way hazard.
According to a paper in the Journal of Family Practice, reported complications from colon cleansing include cramping, abdominal pain, vomiting, rectal perforation, blood poisoning, kidney failure, fatal amoebic infection, and fatal accumulation of gas in the veins. Even if such a consequence is rare, Swoap points out, "it is sure not to happen if I don't let some technician put a hose in my rear."
Everybody poops.

Colons have been doing their job without outside intervention for hundreds of millions of years. "Your colon does not need help in a non-disease state," Swoap says. "Your colon is a pro!" If you want to thank it, step away from the hose and have some broccoli.

While I personally think colon hydrotherapy isn't a good answer for the problems that come from a colon environment that isn't conducive to health... This tid-bit doesn't present anything of valuable information and portrays the colon as something idealized, unassociated with health problems. That would just be a lie if you were to say that. There are a lot of diseases around the colon, and we know a lot about the problems cross-toxin/bacterium problems of the colon.
ReplyDeleteColon hydrotherapy by itself isn't even really a good way to address colon issues. The people that add garlic etc are on a track that makes sense, but still sort of a fruitless effort. It is more like you get to lick the fruit, so ultimately it is fruitless.
@ Field - We must have read two different articles - it presents a lot ! of great information! The article lists a lot a things not to do to your colon. It never 'idealized' (wt heck?) the colon. Disease is not the focus on this article. Please read the article again.
ReplyDeleteYou might as well just right "Don't fix what isn't broken" to that regard. Healthy people are always doing stupid things to try and increase health.
ReplyDeleteI just find that this article isn't really accrediting the reasoning, or offering any suggestions for health that are alternatives to hydrotherapy that is being used for ailments.
Everything is bad and everything is good health recommendations are just so... old. To me it isn't much different than an article that says something like, 'people who ate more of this died less.'
Lets be realistic, despite the dangers, and often poor benefits, people have being doing colon hydrotherapy for freaking-ever; there probably is some reasons why people repeat it. ... I ride my bicycle to work, the store, and other places not because I believe I am perfectly sure I won't be harmed but because I have somewhere to go.
I do appreciate the information discrediting silly pseudo stuff like the section A toilet is not a gym.
@Field, you might be retarded
ReplyDeleteMy, what a frank exchange of ideas.
ReplyDeleteTake two steps and end up with an ad hominem. Anonymous probably honed their fine skills commenting on youtube.
@Field you can't compare people cleansing their colon for years with people riding their bikes for years. That's argument from popularity and is a logical fallacy.
ReplyDeleteThe point is that people will always peddle pseudo mumbo jumbo and people will always buy in to it. Look at ionising bracelets, or homeopathy.
While there can be complications with the colon, that doesn't mean that colonoscopy is the way to go, very far from it. We need proper scientific investigations of the reasons why things go wrong, and investigate solutions. Unfortunately, pumping water up someones butt will not help, and as the article says, can potentially be life threatening.
Some health recommendation really /are/ bad.
Um explain Fecal transplant therapy for me....
ReplyDeletePoint being what if some people need bad bacteria eliminated from the colon?
Up until about a year ago, I would have agreed with most statements in this article - the body is built to be resilient and has mechanisms in place to care and repair itself. This is what we learn in undergraduate, MD and PhD science classes.
ReplyDeleteHowever, I agree with Field when s/he says that there is no mention of health benefits for an injured colon. Yes, there are people who want to "exercise" their digestive system, but there are also other people who have serious digestive problems. And when laxatives, diet changes, and a GI specialist all do nothing for you, sometimes you turn to Alternative Medicine.
Speaking from a personal experience, there is a point in searching for health answers where you will try literally anything. And I have to say, this was the one solution that worked for me. Maybe it was displacing a volatile strain of bacteria in my system, maybe it was dislodging a blockage of some sort... or maybe it was all in my head. But it worked. And in my opinion, the fact that I was able to recover and go on with my life is evidence enough of a health benefit.
