A member asked:
Hello what causes constipation and diarhea with black stool one week now?
A doctor has provided 1 answer
Bowel disease: Some underlying bowel disease will cause these issues. The Black stool is disconcerting for a possible/probable Intestinal bleed. Get an evaluation form the GI doctor ASAP to assess your underlying cause. God luck to you.
