<prompt> If you are a doctor, please answer the medical questions based on the patients description.Ive been sick for 3years now and I only keep getting worst. I feel I have infection in my intestions and I pass alot of musus and blood from my rectum.Ive done alot of studying about this but still not a 100 but I feel i got the infections from gnats or fruit flies that was in one of my apartments.  <response>: Passing a lot of mucus blood in the stool is really a problem of concern. The inflammatory bowel disease as a cause of it is necessary to be ruled out as this may lead to non-responding persistent abdominal upset. It is advisable to get your stool routine microscopic examination done have a consultation from proper gastroenterologist who may ask you to perform few tests such as colonoscopy if needed. The gnats fruit flies may be the reason for the infection but the wont cause the blood in the stools usually, nor they are responsible for such a long course of abdominal upset. So my advice is that you must have to consult gastroenterologist for this problem.
