Hi there , This is my first post but been reading these forums for a while , thank you for accepting me 

I'm just a bit concerned as I've had a persistent change in bowel habits for about 2 +years now 

I went to my gp and he did a stool test which came back at the value of 782 which he said was quite high and obviously some inflammation there 

I was then referred to gastro and waited about 7 months for my appointment which I received a video call from the consultant 

I have now to get a colonoscopy and ct scan , when I asked how long a colonoscopy would take , the consultant unit referred to it as A2 something? What does this mean? I'm sure it was that she said 

and that I would get it before the end of this year 

does anyone know if I'm this is urgent? 
it's worth mentioning I already had a sigmoidoscopy a year ago and everything was fine , I couldn't get the colonoscopy because the prep makes me violently sick , so she's decided that I need to come in to hospital to get a tube in to my stomach and get the prep down that way , sorry for the long post 

much love xx
