Does constipation increase buoyancy?

[boulderjohn]

So the lesson I'm getting from this thread is: no Taco Bell the night before drysuit diving.

Absolutely, especially if you are doing a dive with two hours of required deco.

Meh...as long as it's not confused with a stick. I'm pretty sure wood floats...

So, if the turd weights the same ... as a duck ...

When you want to descend just fart.

I thought I successfully posted this yesterday, hopefully an admin didn’t take it down thinking I was trolling…..

I was way too buoyant this weekend and I’m wondering if being really constipated had something to do with it.

I’ve been diving with 8lbs forever at my current body weight and composition. I did recently suffer an injury that kept me out of the gym for months and I gained weight but lost it again thru diet so maybe I did lose a bit of muscle mass.

On my first dives I felt light with 8lbs which I thought was weird but then the DM said it might have been the Nitrox because the air and Nitrox tanks were made by different manufacturers and he also found himself a bit lighter with the Nitrox tanks. I therefore increased my weight by 2lbs. And all was well. But in one of the dives when I was using air again, which theoretically was a heavier tank, I couldn’t stay down once I got to anround 900 psi and my trim was awful.

For the trim part I think it was because I was using a weight belt. I had lost a weight pocket on the previous dive (not in the water) and so at the least minute switched from weights in pockets and trim pockets to a weight belt.

As far as equipment the only difference was my fins. I switched from Seawing Novas to Seawing Super Novas, but the new fins weigh a tiny bit more, not less.

So the only thing I can think of is that I was constipated, first time that has happened without eating MREs. Could that be the culprit?

I know this is kind of an older post but, although there is not anything scientific to back this up I think it could be a possibility. I was looking for information because I had intestinal surgery many years ago and since then have been diving with basically the same amount of weight. A doctor recently suggested Metamucil to fix some lingering issues and my weight needed changed by about 2 lbs. I was in familiar water with familiar tanks and flat water. I have theories as to why this may have happened but haven't found any scientific information.

you should fart more underwater.

you should fart more underwater.

That's fine until you have one with a lump in it.

This is going to sound like a facetious question, but I'm actually curious: it is harder to get a fart out the deeper you go, or easier, or the same? Is the volume of gas different than normal?

While many have accused me of being full of sh*t, it has never affected the amount of weight I require to blow bubbles; therefore, no constipation does not increase buoyancy.

All you doubting Toms out there should engage in a "Warhammer maneuver" to prove me wrong....See, I am correct.

Now you make me wonder if you can crop dust in 2 dimensions instead of one.

And that most certainly is a facetious question!
