When should I contact my doctor about stool color or texture changes?

Aside from black, red, or maroon stools that may signify bleeding and require urgent assessment and treatment, most color changes are not an emergency. The significance is determined based on other symptoms that might be present.

Women who are pregnant often note changes in their bowel pattern. Stool can turn black because of iron and vitamin supplements. Iron can also turn stool greenish. As the uterus enlarges and increases pressure within the pelvis, constipation may occur and hemorrhoids can develop and cause blood in the stool.

If there is no underlying problem, stool color changes are often due to changes in the diet and will resolve in a couple of days. If this is not the case and changes persist, it is appropriate to contact your doctor and seek medical attention.

Contact your doctor if you have stool color changes and have associated symptoms such as vomiting, diarrhea, fever or abdominal pain.

It is important to remember that every person is different and changes in bowel habit be it color, size, frequency, or consistency (hard or soft) may be normal for one person or a sign of a potential problem for another.
