I have had along term desire for ever larger soap suds enemas. Over the years I have on rare occasions filled myself with 8 qts of soapy water which always ended with my vomiting of soapy water. Not very pleasant. I still take large volume enemas of six to 7 qts. No pain to speak of very stimulating for me. I guess I just have a large capacity gut. I don't have any problems afterwards and my bowl movements return to normal after one or two days.
I doubt any part of this post is true. First, even if this guy did manage an 8 quart enema, the water would never reach his stomach. If he vomited soapy water it's because he drank soapy water, no other reason. i constantly read this same stupid idea that large volume enemas can result in water reaching the stomach. The ileocecal valve (very strong and damned near impossible to force open) stops anything from moving from the large to the small intestine. Then the water would have to force its way past the pyloric valve that separates the small intestine and the stomach. I don't understand the motivation for these people to post bullshit like this.
From another post.
Theoretically, the average human adult colon can hold a volume of around 8 US quarts.
My typical max is 3-4 qts because I'm not trying to win any contests. Once I managed to take in 5 1/2 qts, I'm not sure why I did that, but decided not to do it again after reading about megacolon.
The average human adult colon cannot hold 8 quarts. Work it out yourselves. The average colon is about 1.5 meters (5 feet) long, and can expand to about 7.5 cm (3 inches) in diameter. A little math shows that the "average" colon cannot hold 8 quarts.
Also, I don't what you read about megacolon, but you cannot give yourself a megacolon with large volume enemas. Here is a quote on the possible causes of megacolon, and not one of them includes large volume enemas. you cannot stretch your colon like a balloon that does not return to its original size.
Many pathophysiologic mechanisms have been proposed in an attempt to explain the altered motility seen in acute megacolon; these include the following:
Reflex motor inhibition through splanchnic nerves in response to noxious stimuli
Excess sympathetic motor input (failure to contract)
Excess parasympathetic motor input (failure to relax)
Decreased parasympathetic motor input (failure to contract)
Excess stimulation of peripheral opioid receptors by endogenous or exogenous opioids (initially excess activation followed by prolonged inhibition)
Inhibition of nitric oxide release from inhibitory motor neurons
