How far up does an enema go exactly?

When taken standing up, how many milliliters does it it take to reach the different parts (rectum, sigmoid, descending, traverse, ascending) of the colon?

A lot depends on various body sizes and internal construction. Some can accomplish a fill to the cecum with 1 1/2 to 2 quarts, others (like me) it takes a full gallon (approx, 4 L.).

The colon is about 150 cm long. I seem to recall 6.5 qts about fills it. That might be hard standing up

That is very interesting information. Thank you for sharing that. I once gave a guy a 6 quart enema. So I nearly filled his colon. No wonder he was in such a state of euphoria.

I would assume you can get water all the way to the cecum with less than 6 qts, but I don’t think so standing unless you use a long colon tube. Interesting question, would be interested in others thoughts. I’m not speaking from experience.

It would depend on many things, including but not limited to the size of the person, their posture (standing, sitting, lying), and what is in the colon at the time.

It’s important to bear in mind that the colon is not a rigid pipe and the tissues cannot support a vacuum. Therefore the volume of the lumen is equal to the volume of its contents at any given time, so as the volume of the contents increases—whether by matter coming down from the small intestine, introduced via the anus, or by generation of gas through bacterial action—the colon expands to accommodate it. In a sense, the colon is always full, even if the contents are only mucus.

Hi all,

I can only comment for my personal physique: I'm 6'1 @ 170 not fat but large (ish). 4 qts seems to completely fill my colon. Now to be 'perfectly clear' I can only do that easily if everything is completely clear first - like after an enema series.

I’m 72, 6’1” and weigh about 230 lbs. I took 2-2.5 quart enemas for decades, about 1967- 2017. I increased to about 3-4.5 qts since finding and reading a lot of enema discussions on Zity, because it just felt even more pleasant and satisfying to fill with and hold that much volume. One single time I filled myself with 5 quarts which I enjoyed also with no problems or pain just because I enjoyed the larger pressure and volume sensations and the external distention in the mirror. Even with taking as little as 2 quarts I could always feel and often hear the water sloshing around in my cecum, but I doubt it was as full or distended as it could be with that overall colon volume of enema. I still feel and hear it holding 3-5 quart enema volumes, but it’s probably a good deal more distended using those volumes.

Since the OP’s query specifically addressed standing enemas, I’d just add that none of my >55-year experience of taking enemas was done standing. I just don’t find it pleasant or helpful to be standing during an enema except perhaps at the very end solely to view and perhaps show off my enema belly to someone.

@Texaco88,

Why did you ask this about standing enemas? Do you prefer it that way for some reason?

I can't comment on the specific question regarding volume, but since I use a shower shot type enema while standing regularly, I will say that I generally only flush out up to the splenic flexure that way. I typically lean forward a bit and stretch and can feel the water as it fills and empties the descending colon. If I flush that deeply in the shower, there are generally more returns coming 10-15 minutes later, so I am careful to wait a bit before playtime.
