Hi. Thanks for your query. Read the history of having diarrhea since March 25th started as excretion of clear watery stools, with mucus in it, passed two pills looking things in your stool, took one to the gastro doctor, who said that is not a pill, just passed another one today - red and looks like a kidney beam which has started to worry you... I would advise you the following in such a situation: Get the stool tests for 3 consecutive days. Tests of blood and urine, Ultrasonography of the abdomen. A course of an antibiotic, Metronidazole and probiotics. Passing the bean shaped stool can be either undigested food or can be stool/feces. If the problem persists, you may need further investigations like colonoscopy, CT scan of abdomen and a second opinion of a Gastroenterologist for further diagnosis and management.
