There are multiple reports of "Code Red" causing a reddish brown color to the stools. In fact, multiple foods that are intensely red in color (such as beets) can have the same effect. The important thing is to ensure that the color goes back to normal if you stop drinking the "Code Red."
Obviously the concern here would be for any sort of gastrointestinal bleeding
. Bleeding can give the bowel movements either a bright red color (if the bleeding is lower down) or a dark black color (if the bleeding is higher up). Often there is a bad odor, and the stools may be sticky or tarry. Things that can cause this sort of bleeding include a stomach ulcer, an inflammation of the stomach lining, or hemorrhoids
In someone your age with no active medical problems, these causes of gastrointestinal bleeding would be rare. However, if the stool color is persistently dark and red after stopping the "Code Red" or if you experience any concerning symptoms, such as fatigue, palpitations, shortness of breath, or if you begin vomiting
reddish liquid, then these are all signs that you are likely bleeding and that you should go to the emergency room for treatment immediately.
