These could both potentially be a sign of something going wrong in your digestive system. Both black and bright red stool could be an indicator of bleeding somewhere in the intestines, or from something more minor like hemorrhoids.  Bleeding from the small intestines usually produces melena, or black, tarry stools. Bleeding that originates in lower gastrointestinal tract (such as bleeding from hemorrhoids) usually results in bright red blood. There are other minor factors like diet and medications that could color stools black and red, but if you are concerned, it’s always best to talk to your healthcare provider. Bile contributes to the coloring of stool, so this lack of color could actually indicate the absence of bile. This could mean there’s something blocking a bile duct, which could potentially be an indicator for a serious medical problem. If you ever notice white or light colored stools, make sure you talk to your doctor right away. White stools usually result from steatorrhea (excretions of fat) which can may indicate pancreatic issues. While stool colors can range from browns to yellows to greens and still be considered “normal” and healthy, a medium brown color is the most common in healthy stool. It should be about the same color as a chocolate bar. Stool turns brown through a complicated process in the digestive tract. Basically, the color comes from the protein hemoglobin being broken down to create bilirubin in the liver. Food coloring, leafy vegetables, and even beets can tint stool different colors. This is normal. For example, eating leafy green veggies like kale or spinach could give your stool a green color, and eating beets could potentially turn stool a reddish color. This shouldn’t be cause for alarm, especially if you’ve recently eaten these foods. Only rarely is red stool a serious indicator of an issue in the intestine. Even bright red stool could simply be caused by bleeding from minor and common conditions like hemorrhoids. If you notice your stool is yellow in color (steatorrhea), this could be a sign of a lack of fat absorption in your digestive track. There are many things that could cause problems with absorbing fats, so if this yellow stool persists for more than two days, give your doctor a call. Yellow stool that is also especially smelly or greasy could also be a sign of a problem with or allergy to gluten. Your doctor can confirm whether or not this is the cause. Many medications, from vitamin supplements to anti-diarrheal medications to prescription medications, can cause changes in stool color. These color changes are normal when associated with the use of those medications, so make sure to read the warning or side effects label on anything you take on a regular basis. Iron supplements could potentially turn your stool green or black, while bismuth subsalicylate (the anti-diarrheal found in Pepto Bismol) can also turn stool black. In the first few days after birth, it’s completely normal for some black stool to show up in your baby’s diaper. This will pass within 2-4 days, after the baby has gotten all of the meconium out of its body. It will likely transition into an earthy green color after that, and it will stay a mushy consistency.  Your baby’s poop while breastfeeding will likely be mushy, and either a green or yellow color. This is normal. Formula-fed babies will probably have mushy stool that is more brown than babies that are breastfed, but this is perfectly normal as well.
