I may be completely wrong but will raise the issue anyway. The daily diarrhea episodes may be leaving you dehydrated with an electrolyte imbalance. Also, your gut biome may be even more out of whack than it normally is with your IBD. These then may be aggravating your other conditions. Are you drinking Gator Aid, Boost, Ensure or whatever is compatible with your IBD? And maybe at least eating yogurt for the probiotics?
