Plain Water Absorbtion Rate

How fast does a plain water enema actually absorb into the colon? Like, say you used a liter, how long would it take for that liter of plain water to completely absorb into your body?

I think it will depend many factors most obvious being how hydrated you are. And quite likely it vary from individual to individual, too.

The best just try yourself, number of times.

When I use 2 liters of plain water, I can't hold it for more than 10 minutes, with 1.5 liters I can hold it for almost 15 minutes. I don't know how long it takes to absorb, anyway it's not possible to hold it until it is absorbed.

If the enema is plain water and not saline, and your body is somewhat dehydrated, my guess is that one liter will be absorbed almost in its totality within an hour or two. That is, if you can hold it and not give in to the urge to expel (you'll probably piss like horse afterwards!). If the enema is saline, the osmotic effect will cause water to be draw INTO the colon instead of out. As pointed out, many factors are at play and can impact the rate (or not) of absorption.

My own experience has led me to believe that about a pint (500ml) of a 2.5-quart coffee enema remains behind in me after I expelled all that I could following a 10-minute retention. I have neither the urge nor the ability to expel that last bit, but I make up for it by having an increased frequency to pee for the next hour or so. These observations are based largely on guesswork and feeling, so I cannot really claim them to represent breakthrough peer-reviewed medical research, fit for publication in a prestigious scientific journal.....

You can always try to experimentally measure absorption by first cleaning out most faecal matter from the lower colon, weigh yourself on an accurate scale and then take a plain water one liter enema. Remain on your left side (Sims) to ensure it does not travel higher up into you than the descending colon. Retain for, say, 20 minutes, then poop out everything you can. Then weigh yourself again - that will give you some idea of how much remains behind (assuming absorption) FOR THAT ENEMA, ON THAT DAY. It's probably doomed to be different on another day, due to all the variables as previously noted.

I don't think I ever took a measured amount and then retained it all until it was gone. But, I have weighed myself before and after a coffee retention enema with varying results. As said earlier by someone, the absorption of the enema may be affected by the relative level of hydration in your body and maybe other factors. Of my typical 1 quart coffee enema, rounding to 8 pounds to a gallon of water so 2 pounds to a quart, after I expel there can be anywhere from 4 ounces to 16 ounces that does not come out. Some of that was surely absorbed in the colon, but some is just stuck in there not wanting to come out. I know from experience that when I take a quart of coffee I get an initial urge to expel within a few minutes but I resist that and it goes away after a few minutes. Then I get another round of usually weaker urges to expel at about 15 to 20 minutes and if I let it out then, I retained between 4 to 8 ounces by weight. If I hold back on them, the strong urges just go away and then when I am ready to empty out, I have to push it out and that does not empty me nearly as well as the peristaltic urges do. At the 30 minute mark, after I push out what I can there can be as much as 16 ounces that does not come out. Of the roughly 16 ounces not out, I am guessing that about half (8 ounces) is absorbed and half (8 ounces) is just stuck in the colon. Sometimes that comes out 15 to 30 minutes later, sometimes not. It is not the same each time.

I posted this on another thread, but there is a great episode of a podcast which has an in depth discussion about enema solutions, and specifically what different salinity levels do to your body. I recommend listening to it on whatever platform you use to get your podcasts.
