<s>[INST] Hi doctor, I am a 54 year old male. My weight is 84 kg, and weight is 175 cm. I have done a CT scan before three months, and it showed mild thickening of the sigmoid colon suggestive colitis. I do not have any symptoms of colitis, diarrhea or blood in the stool. I have done stool occult blood tests several times since the report, and all came negative. Also, my CBC test fine. My complaint is a very mild abdominal pain for around two to three times a year. It would last for a week or so along with the feeling that I need to have a bowel movement. Besides the CT report, I have no sense of colitis. Would you explain my symptoms? [/INST] Hi. For further information consult a medical gastroenterologist online --> </s>
