What Your Stool Color Says About Your Health

We all want to be those people, right? The ones who maintain the perfect diet and have the most consistent bowel movement schedule, never having to worry about anything going wrong. While it’s ideal, it’s certainly the exception to the rule. But, that doesn’t mean that you should always have abnormal stool!

If you’re seeing different abnormal colors, here are some potential causes. 


Although green stool isn’t a super large cause for immediate concern, it may mean that your food is moving through your intestine a bit too fast. For example, if you’ve been experiencing diarrhea, the bile doesn’t have time to break down completely, and thus you’re seeing green. 

In addition, if you’re adding more leafy vegetables to your diet, or have consumed anything with large volumes of green food coloring, you may notice that your stool has a green tint.

 Yellow still often implies that you have excess fat due to an issue with absorption, such as celiac disease. You may also notice that your stool is much greasier than usual, or more foul-smelling. 

If you’re eating more gluten, found in breads and grains in cereal, you may see yellow stool as well. It’s important to contact your at Davidson Family Medicine if your stool is yellow as it will typically lead to a diagnosis of some sort. With the proper dietary restrictions you should be able to control this. 


Red stool is an indicator of bleeding in the lower intestinal tract, most often associated with hemorrhoids. If you’re experiencing this, you should contact your doctor as soon as possible. 

If you’re eating a lot of red food coloring, or things like beets, tomato juice, or cranberries, you may also see a red hue. 


If you’re seeing black stool, you may have bleeding in the upper gastrointestinal tract, which is associated with your stomach. Again, contact your doctor as soon as possible if you’re experiencing this. 

In addition, taking iron supplements or ingesting a lot of bismuth (Pepto Bismol) can lead to seeing a black color in your stool.

Testing for active Covid-19 infection is now available in our office.

No need to go anywhere else. Accurate, reliable, and available when you need it.

Davidson Family Medicine now has ample reliable and trustworthy Covid-19 testing capability through our national lab partner Quest Diagnostics.

If there is a need for you or your family to test for infection with or without symptoms, we can do that (safely) here in the office with 1-2 day results. There is no need to travel to an unknown CVS, urgent care clinic, or hospital lab center for these tests.

The Quest PCR test, which is performed through a naso-pharyngeal specimen, is extremely sensitive and specific. It is more accurate and should not be confused with the “Abbott PCR rapid test” that is being performed elsewhere. CVS has given no details about who is performing their tests, the reliability of their tests, and results are not rapid. Click here for the details of the Quest test.

Examples of testing situations:

We continue to offer the IgG antibody blood (serology) tests to determine if a person has had active infection in the past.

Please contact us with any concerns or questions.
