Weight during an enema session

I was just wondering if anyone else weighs themselves or others during an enema session? I don't do it all the time but sometimes I'll weigh myself before an enema and then after taking 4 quarts (which adds about 8 pounds) and then after I'm all done expelling the enema. Typically my weight after the enema session is about 1 or 2 pounds less than before doing the enema(s) due to having less solid waste inside me. I especially enjoy weighing myself if I haven't had a BM in a few days so there's more weight lost due to having an empty colon.

I just did that a few hours ago. I weighed myself before and after an enema.

I have done this from time to time to confirm how much solution is injected and retained. If I'm using a butt plug to assist retention, I do remember to pre-weigh myself while holding it.

I have done that quite a lot of occasions. It is to confirm if residual fluid is well expelled for the following injection in a session. It doesn't tell exactly how my bowel is emptied, because absorption through bowel wall, excretion of matters except for the injected fluid and perspiration from skin need to be taken into account though. Repeat excretions and measurements several times till getting enough confidence for my bowel is ready for the next injection.

I usually end up adding a pound or so, I think some of it is absorbed water. I don't think I have ever ended up lighter than I started.

I do sometimes. It doesn't always mean much because of:

I usually end up adding a pound or so, I think some of it is absorbed water. I don't think I have ever ended up lighter than I started.

I usually drop a pound or so with the "regular" enemas, so I guess I'm usually starting to have some build-up after 3 days (not sure exactly how that works, but my colon is wonky enough to have found a way I suppose). If I wait until I'm officially constipated (3 days since last BM) it's around 5 pounds.

In studies "normal" people generally didn't loose any weight or wound up gaining a slight amount from the retained water, so you're not alone. I'd imagine the stronger enemas or hypertonic ones would be more likely to cause a weight loss, but there's no real need for it so I'd avoid those.

I haven't done it recently, but there have been times past where I weighed myself before and after an enema. Mainly to check that all of the enema was out before moving on to other things. I never believed enemas were a weight loss tool, other than getting a half-pound of poop out of you. In any case, the typical home bathroom scale is not accurate enough for anything other than a rough check anyway. It would seem that sometimes if I had a coffee retention enema I had no weight loss, maybe even a slight gain. Was it because some of it was absorbed? An hour later I peed it out.

When I was much younger I experimented with volume and weight, even standing on the scale while taking an enema... Standing enemas can be a challenge, but it was fun.

As indicated, accuracy back in those days was an issue, so other than seeing the needle move up what looked like 3 or 4 lbs, nada. I assume I must have been absorbing some water for two reasons, I always weighed more after expelling than when I started, and about an hour later I would pass copious amounts of urine.

Later I had a digital scale that read to the tenth of a pound but never tried weighing myself, now I wish I had. All that being said, my enjoyment level is about 2 1/2 quarts. What might have been interesting would to have weighed myself when using the shower nozzle to see how much I had taken. Based on some the results I expect those enemas might have been well over 3 quarts.

My observation was (and is) a low volume flow but with a higher pressure works well and has me holding more than a bag held high with no flow restriction.... But sometimes that's fun.

Weighing after a good fill will definitely increase your weight prior to what you weighed before taking in an enema. But as others have said after expelling the enema, the results can be a bit variable. Most of us would definitely loose weight after expelling- down from our peak fill weight. Yes you will likely loose some weight due to solid waste being expelled but you will likely absorb some of the liquid which adds to your post expel weigh-in. I almost always ended up weighing the same pre and post enema session. So I would imagine I absorb some of the liquid but expelled solid waste which made for no change in final weight.

Water is heavy, salt water heavier.

While it's in you it adds to your body weight.

How much can actually be calculated

The water you absorbed cannot stay for long and should be peed out in a few hours. Your body weight should end up lighter as long as you expelled fecal matters.

This is how I can tell if I've had a "good enema", and all the enema is out. I loose 1 pound if all goes well. If the enema wasn't very effective, or there is still more to come out my weight will show this on the scale. I wonder if the medical community ever did this?

Yes, they do for studies. They take subject's weights before and after as well as "marking" the enema with a known concentration of (usually) PEG and weighing the returns.

Most of the time for "normal" subjects who are not constipated their weight will be slightly higher or the same for most solutions, indicating retention of some of the solution. This includes "isotonic" PEG solution, so it isn't all absorption.

I haven't weighed myself while retaining an enema in years since I can already correlate that with the volume that I have managed to take. I do like to do a before and after weight. When I have been backed up for four or five days, it is not unusual for me to lose 2-3 pounds as a result of the enema induced evacuation of my colon.

I did try this once, weighing myself before and then while holding. After taking a full 2 quart bag I could see a gain of about four pounds. Following that, I then used the shower shot nozzle to fill up as much as I could comfortably hold and stepped out onto the scale. This time I saw a gain of a little over six pounds, suggesting I'd taken somewhere around 3 quarts of water.

Weigh what goes in (A). Expel in bedpan or other receptacle and weigh what comes out (B). Calculate B – A. What could be simpler?

Remember... A pint’s a pound the world ‘round.

WOULDN'T IT BE NICE IF THAT WERE TRUE?

IT ISN'T. It's a cute, but inaccurate little rhyme.

A pint of water weighs 16.68 ounces or 1.0425 pounds.

Heck, a pint's not even a pint the world 'round! U.S. pints and Imperial pints are not the same volume! But we digress...

Let's go have an enema and reflect on our weight! LOL!

You measured incorrectly Suzy. You seem to do little but pontificate and criticize?

I'm just correcting a common error. You're in good company though, even Alton Brown, one of my foodie heroes has quoted that incorrect statement.

A gallon is DEFINED as 3.785412 liters. Yes, that IS THE OFFICIAL WORLD WIDE DEFINITION OF A GALLON. A gallon is NOT defined as four quarts, 128 ounces or anything else. There may be that many ounces or quarts in a gallon, but that is not how it is defined. The gallon is defined in terms of liters. You can look that up.

If you do the math and the conversion from the SI, you will see I am correct. A gallon of water, which is 8 pints, weighs 8.34 pounds -- NOT 8 pounds. By that alone it is obvious a pint of water does not weigh a pound. You can look that up too.

Finally, you should be using the SI system anyway and then you wouldn't have to worry about silly things like what a pint of water weights.

Actually the legal definition of a gallon is 231 cubic inches, and has been for over 200 years. The number Suzie quotes is the metric equivalent of a gallon, however that is NOT how it is defined. Legally 4 quarts makes up a gallon, and 2 pints make up a quart etc. (there are in fact a long list of volumetric sizes in the USA that are now almost never used).. While the US gallon that may in fact be 3.785412 liters, that is an equivalent, not a definition, and even that is actually based upon a determination by the National Institute of Standards and Technology (formerly the Bureau of Standards). NIST is the agency solely responsible in the USA for the actual measurements of all standard weights and measures in the USA. NIST actually has standard weights and measures that define the meaning of all US weights and measures, and all standards in actual use must be traceable back to the NIST standard for whatever it is (pounds, ounces, inches, feet, yards, miles, gallons, pints, quarts, gills, etc) . It is NIST who actually maintain a reference container that actually defines exactly 1 gallon is in the USA.

Actually, that was in the PAST, This is NOW.

The definitions have changed.

We ARE on the metric system for DEFINING ALL "English" units, and yes, you do have to make the conversion. I will find the explanation from NIST--National Institute for Standards and Technology-- and add it to this post when I find it a little later.

Probably only Ken will have the interest and patience to go through this.

Here it is:

This one explains the metric nature of the "English" units. You only need to watch the first minute and a half---https://www.youtube.com/watch?v=SmSJXC6_qQ8

Here is the text from the NIST Publication for the DEFINITION of NOT AN EQUIVALENCY to the pound:

Handbook 44 – 2016 Appendix B –Units and Systems of Measurement

3.2 Standards of Mass.

– The primary standard of mass for this country is United States Prototype Kilogram 20, which is a platinum-iridium cylinder kept at NIST. We know the value of this mass standard in terms of the International Prototype Kilogram, a platinum-iridium standard which is kept at the International Bureau of Weights and Measures.

In Colonial Times the British standards were considered the primary standards of theUnited States. Later, the U.S. avoirdupois pound was defined in terms of the Troy Pound of the Mint, which is a brass standard kept at the United States Mint in Philadelphia. In 1911, the Troy Pound of the Mint was superseded, for coinage purposes, by the Troy Pound of the Institute.

The avoirdupois pound is defined in terms of the kilogram by the relation:

1 avoirdupois pound = 0.453 592 37 kilogram

You see the pound is DEFINED by the metric measure.

The same thing goes for volumetric capacities like the gallon. I am still looking for the text in their paper. It may be in another paper that I cannot find right now. The gallon has been removed from the list of primary units of measure as of 1994-12-31 and it is DEFINED in terms of the SI as 3.785411784 liters EXACTLY.

https://www.youtube.com/watch?v=Oo0jm1PPRuo --this is for added interest.

First: Any measurement of liquid volume, e.g. cubic centimeters, must be done at sea level for complete accuracy.

Second: When converting metric to avoirdupois, rounding takes place.

I believe that is where Suzy gets the added .68 of an ounce comes from.

We are definitely not a metric country. The use of the metric system was legalized in the USA in 1866. Since the 1980's, most industries, particularly those that export, have gone metric. There is no legal requirement to do so. The exact status of the Metric systemin the USA is clearly stated below:

"Status of the Metric System in the United States. – The use of the metric system in this country was legalized by Act of Congress in 1866, but was not made obligatory then or since. Following the signing of the Convention of the Meter in 1875, the United States acquired national prototype standards for the meter and the kilogram. U.S. Prototype Kilogram No. 20 continues to be the primary standard for mass in the United States. It is recalibrated from time to time at the BIPM. The prototype meter has been replaced by modern stabilized lasers following the most recent definition of the meter."

This statement comes for the National Institute of Standard and Technology (NIST) and is clearly stated in

Handbook 44 – 2016 Appendix B – Units and Systems of Measurement

This is a very long way from saying the USA is on the Metric System. Being legalized is a long way from being legally required, as it was in the UK, where everyone was forced to use the Metric system everywhere for a number of years. As the document from NIST clearly states, 'was not made obligatory then or since'. If we were truly a metric country, the use would be required by law. It clearly is NOT.

First: Any measurement of liquid volume, e.g. cubic centimeters, must be done at sea level for complete accuracy.

Second: When converting metric to avoirdupois, rounding takes place.

I believe that is where Suzy gets the added .68 of an ounce comes from.

Sorry, but that is wrong.

Liquid volume is dependent on temperature, not elevation.

Insignificant rounding tales place in conversions between metric and "English" units. Three significant digits is plenty for this. Physical definitions to ten significant digits is preferred.

Your "belief" is incorrect.

======================

Back to the question of "Does a pint of water weigh a pound?" The answer is NO.

DO THIS SIMPLE MATH. A gallon of water weighs 8.34 pounds--you can look that up. A gallon is 8 pints. Divide 8 pints into 8.34 pounds and you get 1.0425 pounds per pint. 1.0425 pounds per pint times 16 ounces equals 16.68 ounces in weight.

You can google the question, "does a pint of water weigh a pound?"

and you will get this answer:

A. There is an old saying, "A pint's a pound, the world around." This number will get you in the ballpark, implying that one pint of water weighs one pound. This number is quite close to a gallon of water's exact weight of 8.336 pounds at 62 degrees Fahrenheit. (One pint weighs 1.04375 pounds.)

Matthew, while we are not officially on the metric system, the metric system --SI-- is used to define all the "English" units of measurement, not merely be an equivalent or conversion factor.

There are three non-metric countries in the world. Myanmar, Liberia and the Unitied States, and that's a sad commentary on the US.

Science uses metric SI and that is the likely reason the SI is used to define non-metric units.

There is NO easy link between volumetric capacity, measures of length and mass in the U.S. Customary system other than cubic units (in^3, ft^3, etc.). The customary system is a mess and a mishmash.

Contrast that to metric where a liter was originally defined as a cubic decimeter and a kilo was a liter of water. Isn't that nice? Modern definitions are much more reliable (based around fundamental constants), but for practical purposes a kilo is still a liter of water.

. . . . Modern definitions are much more reliable (based around fundamental constants), but for practical purposes a kilo is still a liter of water.

YES! That works in SI metric.

However, that does NOT mean that a liquid pint (16 fluid ounces volumetrically) weighs one pound gravimetrically--because IT DOESN'T.

I have weighed myself but have to admit our scales are not real accurate. Typically a 2 lb increase for each quart of water (which weighs 8.33 pounds per gallon) is what I observe. I typically take 2-3 quarts which is about 4-6 lbs increase but find that usually maybe a 0.5 lb to 1.0 lb increase after the enema than initial weighing before the enema. Probably some water absorbed is my guess that is later eliminated when urinating. Denise

Well it’s a good way to shed a few pounds and helps your diet.
