What are symptoms of stool color changes?
Changes in stool color alone do not cause symptoms. The underlying cause of the change in stool color, texture, or form is responsible for any symptoms.
What does it mean when your stool color changes in color, texture, or form?
Bowel movements are usually light to dark brown in color, and there is moderate variation among individuals with respect to stool color, quantity and form. When these changes in stool do occur it can mean that there may be an illness affecting the gastrointestinal (GI) tract or the entire body.
