Lactose intolerance doesn't cause bleeding in the colon, and the damage done by UC isn't because of poor digestion.
You'll have symptoms from milk containing products/foods in the colon because it doesn't have the enzymes to break down the undigested lactose (milk sugar). I'll assume that if an inflamed colon has more symptoms to deal with, it'll react even more. It'll probably produce more mucus to try to protect it (which is a good thing from my perspective)..the bleeding happens because the colon is fragile, and anything that passes over it will cause bleeding...maybe even the very act of peristalsis will cause it because blood may be pooled in there anyway. The colon is quite effective in elimination for UCers.
The point is to help calm the inflammation down, in turn, the reactions.
For discomfort from undigested lactose, avoidance is good.
You can get that checked from the doc..there are a few tests they do.
Damage at the cellular level is caused by the inflammation and the act of the disease itself, depending on if it's affected the mucosal layer or has gone a bit deeper into the submucosal layer.
Here's why you're bleeding...you still have inflammation. You've just been tapering off prednisone..your body has to now start producing the cortisol that was being put into your body via the pred. You're also NOT on enough rectal meds..since you've already deduced that your inflammation is low/rectally.
Please also consider to take a good probiotic..that will also help with lactose intolerance.
Consider to take the suppositories 3 times a day...that will ease the rectal inflammation.
