Ulcerative Colitis And Diverticular - Budenofalk Granules And Acidophilus

My mum was diagnosed with both colitis and diverticulitis, she was put on a (9mg) 2 month course of Budenofalk granules reduced to 1 week 6mg and then finally 1 week 3mg.  The diarrhea and need to go to the toilet eased during this time, however she has now been of the medication and is back to having to rush to the toilet again, we are awaiting for a follow up appointment at the hospital but this isnt until next month, she visited her gp last week in the hope of some help/advice - they were only able to try and get the appointment pulled forward.  She has lost just over 3 stone since November, and we are at our wits end as nothing she seems to eat/drink remains for long, within 30 minutes of having anything to eat she has to visit the loo.   She has been taking the acidophilus 10 billion since the beginning of the year.  Can anyone offer any advice is there others that are in this unfortunate situation,  she feels like she is wasting away and a prisoner inside her own home.
