mucoid plaque

recently i had a barium enima,would this have shown up any mucoid plaque?the consultant said it showed up diverticular disease,but he didn't mention mucoid plaque,i have been doing Bentonite and psyllium for a few weeks but have to keep stopping due to constipation(this is what i'm trying to get rid of).If i do have mucoid plaque i need to get rid of it to help the diverticular disease,any suggestions?
Thanks.
