fecal calprotectin result

Hi, I am wondering if anyone could ease my mind as I am really worried.

Since the last 20 odd years I have suffered with IBS on and off. Never had a test to confirm it, just told i had it by my GP when I was in my 20's.

Anyway 2 years ago I had a FIT test done due to the gut problem which came back negative.

March this year i became constipated due to quitting smoking. I think it was where my problems started. I basically started to see large amounts of bloods in the toilet bowl. Then i started having diarhea still with lots of blood.

2 seperate doctors checked and said I had piles and tried the creams, but it only settled it for a couple of weeks and then it started again. But the toilet needs had got worse where i needed the loo at one point about 15 times in a day..

The doctor decided to get a FIT test done which came back at 30.8 (abnormal) and a fecal calprotectin has just come back normal. But I have lost weight of 8lb in 3 months. I also have had a contrast CT scan 5 weeks ago which was normal.

I have a booked telephone consultation this Friday with colonoscopy team. 

I am really worried. 

Thanks for reading this far.
