I had mucus and blood in my stool it's geting better just litte mucus i called my dr she said i'm fine and constipated can anxiey make you stool bad?

Possibly: Highly anxious states can sometimes cause loose stools/diarrhea and stomach cramping. However, the presence of blood is usually not a symptom. It could be the blood came from a hemorrhoid or possibly from inflammation within the colon. The best answer is if it happens again ask your physician to further evaluate it or refer you to a GI physician for evaluation.
