Conversation: The conversation between human and AI assistant.
[|Human|] My husband has been really sick for the past couple of days. He has had really bad diarrhea and has been throwing up. There is occasionally blood in his vomit and there is quite a bit of blood in his stools. He has had blood in his stools off and on for the past couple of months but it has never been this bad. He has really bad pain in his lower abdomen/upper pelvic region. It hurts for him to laugh, cough, or bend over. What could be wrong with him?
[|AI|]  Hi and thanks for the query, I suggest he deserves a proper clinical evaluation. Blood in stool deserves, especially when chronic in elderly men deserves exclusion of a tumor of the colon. A colonoscopy and testing for occult blood in stool might be appropriate. Depending on whether its bright red or dark blood, we could have an idea of the source of the bleeding, whether upper gastrointestinal tract bleeding or lower tract infection. Stool examinations could help exclude to the possibility of amoebas. A proper clinical evaluation to exclude peptic ulcer disease, a microscopy could be useful. An abdominal ultrasound could also be useful to evaluate the state of abdominal organs. I suggest you consult an internist or gastrointestinal for a proper clinical evaluation. Thanks and best regards, Luchuo, MD.
