This article explores the causes and symptoms of dark-colored stools, highlighting how diet, medications, and health conditions influence stool color. Recognizing these signs is vital for diagnosing underlying health issues like internal bleeding or digestive disorders, emphasizing the importance of monitoring additional symptoms for proper medical attention.

Identifying the Reasons and Symptoms of Dark-Colored Stools

Stools that are dark or resemble tar, ranging from deep brown to black, may indicate various health concerns. The color of your stool offers important clues about your digestive health and overall well-being. Normal stool typically appears in shades of medium to dark brown, signifying proper digestion and liver function. A shift to yellow or yellow-brown can suggest fat absorption issues, often accompanied by abdominal discomfort.

Dark black stools might be caused by certain medications or internal bleeding within the gastrointestinal tract. Various factors contribute to black stool, discussed below.
