- Do you think you can be sexy

and have diarrhea at the same time?

- Not while you're having the diarrhea, no.

- I'm here today with Dr. Deleve, who is a poop expert,

also known as a gastroenterologist, right?

- Yes

- Okay, and what does that mean exactly?

- That's a doctor who takes care of people

who have problems with their swallowing,

their stomach, or their guts.

- Okay, so you see a lot of poop.

- See a lot of poop.

- I asked my coworkers to send me pictures of their poop.

And they did and it was so gross

that I could not show them to you.

(laughing)

I questioned my sanity, looking at my coworkers' poops.

Then what I had them do is describe them

to an artist who made some artist-renderings.

I was wondering if you could grade the poops.

- Absolutely.

- Here we have this one.

- Yeah, those are little pebble-like

stools and the reason they're like that

is because the poop is taking too long to get through

the gut so it's getting dried out.

That's a sign of constipation.

- That's one person who I guess was constipated.

- This is a poop that's not the ideal poop

but it's still within the normal range.

It's slightly constipated,

it's rocks kind of congregated into a sausage

and that's a little more on the constipated side

than a smooth sausage would be.

Ah, the perfect sausage.

That's a log.

If you want a stool that looks like the ideal poop,

this is the ideal poop.

- This is it, whoever gave me this one,

I think it was you (bleep), you got the perfect poop.

- That's a green poop.

- [Voiceover] So green is okay?

- [Voiceover] Green is a perfect poop.

- Yeah?

- Normal is brown, green, or yellow.

That's all normal.

- We got this one.

- That's a mushier stool, that looks like it's heading

towards diarrhea when you're getting these

little flakes that are kind of watery at the edges.

That suggests that you're developing

a looser stool if that's not your normal pattern.

Then you have to wonder about dietary things

you might be ingesting like lactose,

if you're lactose-intolerant,

or fructose, if you're fructose-intolerant.

- Too many dried fruits?

- Too many dried fruits, too much fruit juice.

- Alright, so...

- That's a very nicely shaped log with some corn in it.

That's perfectly normal.

- Why do we see it, why does it just come out as corn?

- It's not well digested.

It travels through you and that's probably a good thing,

it means your transit time from mouth

to the toilet bowl is fast.

- This is (bleep).

- I've not really seen a Mt. Everest-looking stool

but it looks to me like this came out more like

toothpaste and again it's a softer stool.

Some people have one loose stool a day.

If that's your normal pattern, that can be okay.

- How do you know when you're

having a poop that's problematic?

- You probably should see a doctor if

what you're normally doing suddenly changes.

You should see a doctor if your stools

are suddenly coming out pencil-thin.

Consistently, not one day,

but consistently coming out really thin.

If it's coming out really funny colors like

pitch-black or bloody or white.

- I'm not afraid to talk about poop,

you certainly are not afraid to talk about poop,

it's your career.

Why do you think people are so

uncomfortable discussing this?

- It's a mystery to me why people are

as jittery about talking about poop as they are.

I think it's because it stinks and people just don't

like talking about bodily functions that stink.
