The normal color of adult stool is usually brown, yellow or yellowish brown.
The color of adult feces is related to the color of the food ingested. If a large amount of green food is eaten, the feces may be green, and this is normal. In addition, if you eat a lot of animal blood, you may have black feces, which is also normal. If you have black feces frequently, you need to pay attention to it, and it may be caused by intestinal diseases.
If black feces appear frequently and are not related to diet, it may be caused by intestinal bleeding, ulcerative colitis, or intestinal tumors. If there is white clay-like stool, it is likely to be caused by obstruction of the bile duct, such as bile duct stones and bile duct tumors.
The color of adult stools can vary, depending on diet and medication. If you notice an abnormal color in your stool, you should seek medical attention.
