Vast amounts of poo

Hi I take Mesalazine 800 mg.  twice daily. Also Immuprobio which is a probiotic 50 billion mix.  I have been in remission now from Proctitus since February. 
Before the Proctitus my BM's were always very irregular, perhaps 3 times a week, I always thought of myself as being naturally a constipated person, only going more when I was nervous. (also had IBS)  However now it seems to be normal for me to go at least 3 times per day, with vast quantities. In fact I don't know where it all comes from!!!    My BM's are normal,  no blood, normal  toothpaste consistency and not smelly.  I do eat lots of fruit and veg and wouldn't be concerned but there seems to be so much when before there was so little!! 
Would anyone know if it could be the medication or perhaps the probiotic which I don't want to stop taking.

I remember those days. I too wondered where it all came from but I know now it was because my colon was not healthy and functioning properly. In that condition the food is not being processed properly so more is being sent out than normal. Also the cells lining the colon are shed (normal) which adds to the volume.

I was constipated pre-UC too but constipation is part of UC as well.
Keep working on reducing your inflammation and the "massive amounts" will slowly go back to normal amount.
It could be you are sensitive to Mesalazine or that kind of probiotic (people can be) or perhaps it's something you are eating.
When I eat something my colon dislikes it can trigger a wave of BM's until all is gone and I'm exhausted. Thankfully that is in my past (having figured out what foods/drinks my gut hates).

Good luck.

I feel like I always had 2 or 3 as long as I could remember before uc, but they were normal looking, rarely had diarrhea

Fruits and veggies have lots of fibre and water. What else are you eating?

Are you taking fibre supplements?

Depends on what and how much I eat as well...sometimes I'll have two bms about a half hour apart (so in effect it's one, but the complete download hasn't happened at one time)...

Fruits and veggies will also quicken the digestive tract a bit...so I would expect that is in part what's going on.

The fact that you're not on any rectal meds for maintenance is a bit concerning considering you have limited UC.
How urgent are your bms....like NOW or that you get inklings, then the urge, then can hold a bit, then eventually it's NOW ?
 Thanks for your replies I really appreciate it.
I eat normally, maybe too much fruit. In the past i could always eat loads of fruit and was still constipated. This hasn't happened for some time now, if I havn't been for a couple of days I take a "Movicol". I do this, because when my Proctitus started constipation was a real problem and i suppose i want to prevent it from happening again. This hasn't happened for some time now.

I get the inkling I need to go and can hold it for a while and then really need to go. As the day goes on I can hold it longer. I stopped the rectal enemas very slowly back in February and thought as the bleeding hadn't returned everything is ok. There is no smell now, which was pretty foul during my flare and that's why I keep taking the probiotics. Everything looks normal it's just there is such a lot of it.
