Hi, I am 30 years old and lately my poop has been comming out a little flat. Last month my poop was round and I was going on a regular basis. What's the deal?

Dear Tim,

Thanks for asking this question!

I have received a few questions about flat poo of late. Wonder if something is going on....Conspiracy, or coincidence....Lets talk about poo, shall we?

Just like people, poop comes in many different shapes, sizes, and colors. Any similarity between people and stools should end there, however.

The interior of the colon is round, so the shape of poop is usual round, too. A change in stool shape or caliber can be the result of a mass that is affecting the lumen of the bowel. Though many different stool appearances are considered normal, any change from your "usual" bowel habits should be considered abnormal.

Get yourself checked out. This will likely involve a colonoscopy, which is a really fun procedure that involves a 4 foot long "snake" being inserted up your ass, drugs, and a day off work. (Not unlike the ol' college days, eh Tim?)

In all likelihood every thing is ok, but it never hurts (ok, it hurts sometimes) to get a clean bill of health for the old bunghole.

Good luck!
