Re: Dark green stool
If you have the occasional green stool, dont panic. Most likely it is normal, and there is a perfectly reasonable explanation. Think about the foods you ate, any vitamins or supplements you took.(even if they're not green in color)
There can be many reasons why a stool appears to be green. The first and most obvious reason is eating green foods. Green, leafy vegetables contain chlorophyll which could be coloring the stool green. Iron supplements or even foods that are rich in iron can also give stools a green tinge.
If green stool continues, or your bowel habits have changed in other ways, you may want to call your doctor. This is especially true if you are experiencing diarrhea which can be an indication of other problems or could lead to dehydration.
