Hello,
Going on 3 weeks ago I passed bloody mucus in my stool a few small amounts over the course of an evening..The next morning my stools returned to somewhat normal..then over the course of the weekend I had many small urgent movements with no blood but the colors went from bright green to lighter brown..Finally about 4 days after I passed this mucusy blood I did it again...and returned to normal a short time later...Now almost 2 weeks later I have added better foods to my diet and have had great bowel movements some with a little more mucus than others but each day they are more normal and less frequent...Here is what I am worried most about and that is the fact while these have been my only symptoms I have not had any pain and I have dropped 7-9 pounds over the course of this month...The only thing I have removed from my diet over the last few weeks is beer and I always drank 2-4 a day and 5-10 on the weekend...I am 6ft was 185ish and now close to 177ish..I have high anxiety and have worried sick over this situation since it has happened and was wanting to know can my worry cause weight loss even though I have still had a huge appetite? I have a Colonoscopy sched 2 days from now and I am only 33..Sometimes during the day I cant help but think I am gonna be a goner and other times I am kicking myself for putting myself in this state..any comfort on the weight loss would be great I have no family history of this either..and am fairly atheletic..Thanks
