I’m worried I’m taking iron tablets prescribed by the general physician (GP). I’ve been taking them for more than 3 years, stools have always been black, and for the past week the color has changed to light brown like as if I was not taking iron! I wonder if I need to see the GP, I have had no change in my diet.

I have been diagnosed with inoperable and incurable bile duct cancer. The cancer has spread to both lobes of the liver. Lately my stools have been mostly black.

Taking too much aspirin was the cause of my stool color to change.

I'm worried. A few days ago I noticed a little blood in my stool and today my stool was black but no trace of blood.

I am not sure of the cause of change in my stool. It is black, looks like tar, and same size of regular stool.

After a bout of diarrhea stools now are black. I am worried if this is a matter of concern.

Almost every morning after I eat breakfast, I have watery stools with a green color to the water. I have little time to get to the bathroom. I usually eat oatmeal with fruit and yogurt. I do not have cramps or pain; just embarrassment when I don't make it to the bathroom.

I had diarrhea, up to 20 times on the last day of 14 day duration. I then had three bowel movements after being on electrolyte solution for 2 days. What seemed strange was that they were all off-white in color.


Bowel regularity means a bowel movement every day. See Answer
