Dark-colored stools, often appearing black or tar-like, can provide vital clues about your health. These changes in stool color are often linked to underlying medical conditions or dietary factors. Typically, normal bowel movements are brown, signaling healthy digestion. Variations to yellow or yellow-brown may indicate issues like fat absorption problems. When stools turn very dark or black, it might result from certain foods, medications, or internal bleeding. Recognizing associated symptoms helps determine if medical attention is needed.
Normal stools range from light to dark brown, reflecting proper digestion and liver health. Deviations such as yellowish shades can point to digestive issues, especially with fat absorption. Conversely, very dark or black stools could signal internal bleeding or the influence of specific foods or drugs.
