Why does fiber soften stool?

Is this just conventional wisdom?

It means that the population of bacteria increases and therefore the number of dead bacteria increase proportionately.

@MiMintzer: senakot didn't work by itself, I had to take that plus colace, and you are 100 percent right about the water. @Renee I eat both, but more insoluble.

What kind of fiber are you eating? You need both insoluble and soluble. Insoluble is the undigestible, stringy tough stuff, like lettuce and the skins of many veg. Soluble is the kind that absorbs water. Examples are starchy veg, bananas and white rice.

Wouldn't this imply that consuming soluble fiber kills bacteria?

You need to make sure that you are drinking plenty of fluids for the fiber to absorb. In your case, Chinaeskimo, if you are taking opiate pain meds then fiber may not be your best choice for constipation. You might want to try something like senakot, which is a stimulant laxitive and see if that helps.

Fiber absorbs water and the increase in water in the stool causes it to be softer and easier to pass.

Half the dry weight of stools is dead bacteria/etc. The more dead bacteria your stools contain the softer they'll be. Most of the bacteria in your gut feed on soluble fibre (The "Good" kind that is). So when you eat more fibre your gut bacteria can multiply and more dead weight comes out the other end.

That's how I understand it anyway.

I eat a lot of fiber, and if I take pain medicine, it doesn't matter how much fiber I eat, I get hard dry painful stool and need to take a stool softener. So this makes me wonder how much fiber actually softens stools and why the stool softener contains no fiber?
