why the excrement is normally brown?

Dunno. I'd guess it's atleast partially due to biliary salts because people with an obstucted common bile duct have light yellow stools.

I assume you meant feces. That depends on the source of course. But if you've been noticing it, you should make an appointment to see your physician, soon.

Front to back.  Just think, you don't want to be pulling poo/bacteria into your vagina and urethra (causing UTIs and other nasty infections).  As far as the "pooting" goes, that's normal, I believe teenagers  call it "queefing"?  It happens because air goes up and gets trapped and then if you contract your stomach muscles at all then it comes out.  It happens a lot when condoms are in use because the latex provides an air tight seal and the man pushes already present air up the canal... (or at least that's when the BIG ones happen LOL)

Healthy people can have green poop if they eat a diet rich in leafy green vegetables, or if they consume large quantities of food coloring (in ice cream, cake frosting etc.). \n    Green poop can also be caused by excess iron in the diet, from dietary supplements, for example. If the body does not absorb all the iron consumed, the iron may stain the poop green, the color of iron (II) salts. Ordinarily, the green color may be masked by the normal brown poop color, but if digestion is thrown off by illness so that bilirubin is less concentrated in the intestine, the green color may become apparent. This can happen when a person is afflicted with diarrhea. \n    Green poop in sick babies may come from iron in baby formula not being properly absorbed, or by green pigments in bile salts (again, green from iron).

Bile pigments.  The specific compound responsible is called bilirubin.\n\nThat said, try drinking a lot of grape gatorade and eating a lot of black licorice and see what color you get.  It won't be brown.  :)

Yes sweetie, it is just old blood, that's why it is brown. A phone call to whom ever prescribes your birth control wouldn't hurt. But I'm sure they will tell you the same thing.

Its brown colouration comes from a combination of bile and dead red blood cells. In newborn babies, fecal matter is initially yellow/green after the meconium. This colouration comes from the presence of bile alone. In time, as the body starts expelling excess dead red blood cells, it acquires its familiar brown appearance. Throughout the life of an ordinary human, one may experience many types of feces. A "green" and sometimes "clay-like" appearance to the feces is a result in a lack of blood cells expelled. Bile overload is very rare, and not a health threat. Food may sometimes appear in the feces. Common undigested foods found in human feces are seeds, nuts, corn, and beans, mainly for their high fiber content.

It's perfectly normal.  I have brown discharge from my anus every day.

Yes, dark bowls is an indication of a high preserviative intake... Try the site below... They make a very good colon cleaner. When your colon is cleaned your bowel movemnts will return to a milky brown color which is normal.... \n\nI am not sure about dark bowels meaning you have blood in them. I have never heard or read that being a cause.

I use making tea as an example. You boil water and put it in a clean glass container. Add a tea bag. Watch the brown color diffuse from the bag (high concentration) to the rest of the container (low concentration). This happens without help (passive transport) down its concentration gradient.

This is actually a fair question.  First, 'poop' is brown because it is a mixture of green and rusty red.  The red comes from retired blood cells that are being excreted.  The greenish yellow is from bile, a substance present in your digestive system.  When there is significantly more bile than retired blood, the poo is more green (this is my many babies have green poo, their bodies aren't old enough to have retired enought red blood cells).  Bile 'overload' is somewhat rare, but is not a health issue.  If you experience abdominal cramping, dark/black stool or stool that is very thin (perhaps no thicker than a pencil) these can signs of very serious medical problems.  But for now, you're probably fine. Regards :)

The liver creates bile and mixes it with feces or stool and that gives it the brown color. Foods affect it a little. Eat greens with chlorophyll and that has green color. Eat lots of carrots and it is a lighter brown.

Stool of a dark color and sometimes tarry quality.  It can be indicative of blood in the gastro-intestinal tract.

In the medical laboratory a urine specimen received for analysis bearing the characteristics you describe could very well indicate a possible liver condition.  A deep yellow or brownish coloration may be due to bilirubin or excessive urobilinogen.  Also through my studies and experience a foamy urine also frequently indicates the prescence of bilirubin.  The smell could be due to infection.  Blood could also very well be found in a urine such as this.  I would think your best move would be to present this information to a medical doctor as soon as possible.  Even if nothing comes of it-I feel like there might be something going on that needs to be addressed quickly.  Better safe than sorry.

Poo smells so bad that we know exactly what it is and so we dont eat it (caveman days) Its brown because if you mix many colours the result is always brown. Also the main colours in the stomach are red (blood) and yellow (bile) which when mixed makes brown.

Basically add the water lost through diarrhoea to the water lost through normal peeing and that's more water lost than usual therefore it needs to be replaced. When you pee it's perfectly normal therefore your body can handle the amount of water lost but diarrhoea isn't part of your body's normal digestion process therefore it's excess water that's lost.\n\nWhat happens when you get diarrhoea is your body has some sort of virus or bug or just something that it does't like therefore the digestive system (which is the system that gets rids of wastes and your body's toxins) will work faster than normal to get rid of that substance. Usually when digested food gets to the large intestine (the part right before your anus which is where the poo comes out) it absorbs any excess water and produces "normal consistency" poo. However because your entire digestive system is working faster than usual the digested food just kinda "zooms" through the large intestine without time for it to absorb the water therefore it comes out more "watery" than usual. Because this water was not absorbed into your body when it should have been, you will be lacking water which is why you need to drink plenty of water to replace it. \n\nHmm... does that make sense? Lol.
