why is poop for the most part usually brown?

It is because secreted into the bowel are two substances which colour it - Bilirubin which is redish, and biliverdin which is greenish. Put them together and you get brown.

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.

Assuming that you are talking about feces.  Your stool color is determined by what you eat.  Black stools are a sign that you have eaten a meal high in iron or taken an iron supplement.  If that is not what you are talking about, sorry.

I like my stool to match all the other furniture in the room.\n\nOh wait, you're talking about THAT stool. I think it depends on what you eat. You may want to give more information about the size and color of your stool and others can let you know if it sounds normal.\n\nGood luck.

Blood in the stool can be bright red, maroon in color, black and tarry, or occult (not visible to the naked eye). Causes of blood in stool range from harmless, annoying conditions of the gastrointestinal tract such as hemorrhoids to serious conditions such as cancer. Blood in the stool should be evaluated by a healthcare professional. \n\nRectal bleeding (known medically as hematochezia) refers to passage of bright red blood from the anus, often mixed with stool and/or blood clots. Most rectal bleeding comes from the colon, rectum, or anus. The color of the blood during rectal bleeding often depends on the location of the bleeding in the gastrointestinal tract. Generally, the closer the bleeding site is to the anus, the blood will be a brighter red. Thus, bleeding from the anus, rectum, and the sigmoid colon tend to be bright red, whereas bleeding from the transverse colon and the right colon (transverse and right colon are several feet away from the anus) tend to be dark red or maroon colored. \n\nIn some patients bleeding can be black and “tarry” (sticky) and foul smelling. The black, smelly and tarry stool is called melena. Melena occurs when the blood is in the colon long enough for the bacteria in the colon to break it down into chemicals (hematin) that are black. Therefore, melena usually signifies bleeding is from the upper gastrointestinal tract (for example: bleeding from ulcers in the stomach or the duodenum or from the small intestine) because the blood usually is in the gastrointestinal tract for a longer period of time before it exits the body. Sometimes melena may occur with bleeding from the right colon. On the other hand, blood from the sigmoid colon and the rectum usually does not stay in the colon long enough for the bacteria to turn it black. Rarely, massive bleeding from the right colon, from the small intestine, or from ulcers of the stomach or duodenal can cause rapid transit of the blood through the gastrointestinal tract and result in bright red rectal bleeding. In these situations, the blood is moving through the colon so rapidly that there is not enough time for the bacteria to turn the blood black.\n\nSometimes, bleeding from the gastrointestinal tract can be too slow to cause either rectal bleeding or melena. In these patients bleeding is occult (not visible to the naked eyes). The blood is found only by testing the stool for blood (fecal occult blood testing) in the laboratory. Occult bleeding has many of the same causes as rectal bleeding and may result in the same symptoms as rectal bleeding. It is often associated with anemia that is due to loss of iron along with the blood (iron deficiency anemia).

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

There is a breakdown product of hemoglobin (a major component of red blood cells) called bilirubin.  Bilirubin is eliminated through urination and defecation but it breaks down into the other products.  One of the products is yellow (so that's y pee is yellow)....the other product is brown (and that's y poop is brown)

It's funny to know that most of us think green bowel is disgusting & that were either dying or very ill. But contrary to popular belief, you want your bile a bright green. Yellow, orangish, & brown colored bile represent toxin accumulation in your body.

that is bile.  after you have vomited everything else the last secretion is bile and it is brown, it is normal.

I would say alot of vegetables or laxatives. Mine is brown now but when I took laxatives they were runny and green. Something in the formula I guess.

Due to your diet. If you lack fibre in your diet you will get nuggets. Your poo indicates your health.

Changes in the color, consistency, and frequency of bowel movements is known as a "change in bowel habits." Most people have experienced infrequent bouts of diarrhea, constipation, or a strange discoloration of their stool at one time or another.\n\nIn some cases, an unusual stool color is harmless and can be attributed to a particular food or medication—but not always. Changes in bowel habits that persist can be a serious matter and should always be investigated by a physician. Black or red stools can indicate internal bleeding somewhere in the gastrointestinal tract.\n\nCauses of black colored stools (known as melena)\n \nacidified blood \nblood from higher in the digestive tract \niron supplements or foods high in iron \nPepto-Bismol or other medicines containing bismuth \nblack licorice \nlarge amounts of spinach or other greens \nblueberries \naspirin \nother foods dark in color such as chocolate sandwich cookies (Oreos)\n\nCauses of red colored stools (known as hematochezia) \n\nblood \nhemorrhoids \nred gelatin, popsicles, or Kool-Aid \ntomato juice or soup \nlarge amounts beets\n\nCauses of pale or clay colored stools \n\nlack of bile salt (bile salt gives stool its brownish color) \nantacids containing aluminum hydroxide \nbarium from a recent barium enema test \nhepatitis\n\nCauses of green colored stool:\n\nlarge amounts of green, leafy vegetables \ngreen or purple artificial coloring (popsicles, Kool-Aid, gelatin) \niron supplements \nrapid transit or decreased colonic transit time\n\nCauses of orange colored stools: \n\nsome medications (such as beta-carotene and rifampen) \nfoods high in beta-carotene: carrots, sweet potatoes, apricots, winter squash, pumpkin, cantaloupe, and mangoes \n\nIf a change in stool color cannot be attributed to a dietary reason, or is accompanied by any other symptoms (such as diarrhea, constipation, weakness, or dizziness), a doctor should be consulted.\n\n\nI hope this helps...\n\nDon
