Dysentery with blood is usually caused by E. coli infection, when the mucous membrane in the intestine is prone to damage, so there is usually pus and blood stool in dysentery. The treatment usually requires antibiotics and anti-inflammatory drugs, and a light, warm diet with less cold food. In addition to dysentery with blood, it may also be diarrhea caused by eating some unclean food. And when diarrhea is easy to produce irritation at the anus, and even cause symptoms such as bleeding hemorrhoids. In addition, the possibility of enteritis is not excluded. So if dysentery with blood does not appear other obvious symptoms, or itself is not very serious can be treated with medication. However, if the bleeding does not improve, or is even more serious, you should pay attention to it and go to the hospital for a colonoscopy to clarify and examine it.
