Stool routine with leukocytes and red blood cells may be intestinal infection, or intestinal non-infectious inflammation. 1. Intestinal infections: routine stool with leukocytes and red blood cells may be caused by intestinal infections, commonly bacterial infections, such as bacterial dysentery, acute gastroenteritis and other diseases, and parasitic infections such as amoebic dysentery. Infectious inflammation will cause the appearance of white blood cells and red blood cells in the stool. 2. Non-infectious inflammation of the intestinal tract: Inflammatory bowel disease caused by immune factors, genetic factors, psychiatric factors, intestinal flora imbalance, such as ulcerative colitis, Crohn’s disease, ischemic colitis and so on. These inflammatory conditions cause damage to the intestinal mucosa, which can also cause red and white blood cells in the stool. Stool routine with red, white blood cells, should seek medical attention, under the guidance of the doctor early to clarify the cause of the disease, reasonable treatment.
