The gross examination of feces involves assessing the physical characteristics of stool, including its color, consistency, shape, size, and odor. Normal feces are typically brown, formed, and have a mild odor, while variations can indicate underlying health issues. For example, pale or clay-colored stool may suggest liver problems, while black or tarry stool can indicate bleeding in the upper gastrointestinal tract. Additionally, the presence of mucus, blood, or unusual shapes can provide important diagnostic clues.
