Hello, I read your message and I understand your concern. Before running into final conclusions, I would like to know if you have other health diseases or health condition and anything else that you notice in yourself. The most common cause of fresh blood in stool is hemorrhoids. If it is of dark color then it can be because of an upper hemorrhage in your intestines or stomach. If you suffer of hemorrhoids, that s explaining blood in stool. Otherwise, further tests are required to determine the right cause including: - colonoscopy - occult fecal blood tests - physical examination by proctologist Blue lips are usually signs of hypotension and other heart and circulatory troubles (e.g. anemia). As you think you re having foggy thoughts, my advice is to see a doctor and do further tests in order to distinguish hemorrhage and a possible thrombosis in your upper body vessels. You may go under blood tests and some radiology like CT scan. Hope this is helpful. All the best! Dr.Albana
