the diuretics can and do make stools haard because it is meant to dehydrate you. Perhaps you can ask to take something else.
also a sedentary life is not good for digestion. The intestines need body movements to move the foods along. exercise will also help ciculate blood to the bum and keep it from pooling into hemmies.
I use rutin for my hemmies. don't know why it helps me but it does. I found brand makes a difference. the greener the pill the better. 3000-6000 mg a day during a flare and 1000-3000 for maintenance.
