<s>[INST] My husband has been having bloody dirreahea lately and hes not sure whats causing it. He says he doesnt have any pain of any kind. He hasnt eaten anything unusual or been anywhere. He has been under a lot of stress lately with work and his mother recently passing. [/INST] Hi madam, welcome to Chat Doctor, I understand your problem, Bloody diarrhea is a potentially critical condition in which there is blood mixed in with loose, watery stools. The blood can arise from anywhere along your digestive tract, from the mouth to the anus. Bloody diarrhea is often a sign of gastrointestinal bleeding due to injury or disease. Diarrhea that contains bright red or maroon-colored blood may be referred to as hematochezia, while Elena is used to describe black, tarry, and smelly diarrhea. Bloody diarrhea may also be referred to as dysentery, which is usually caused by a bacterial infection. Hope u satisfy with my answer, thank u </s>
