Hope,
The fact that you are on Lomotil suggests to me your issue is spasmodic pouch or excessive motility. I did have this issue for a couple years after takedown. The explosive diarrhea from excess motility comes in machine gun like bursts of BMs after eating meals. I found that LomotiL is only effective if taken 45 minutes before meals. If not, it's useless, or at least it was for me,because excess motility is the root of the issue and it's triggered by eating anything. So you need to get that pill absorbed before eating not after.
In my case the problem gradually went away. If you have had any surgery within the past 2-3 years, it sometimes takes a while for normal motility to return. In my case I had bowel surgeries in 1992, 1998, and 2000. The last time I had any motility issue was over 20 years ago. Lomotil is a distant memory now, but I found it highly effective when used correctly, meaning 45 minutes before you eat rather than at structured intervals. It shut down the explosive diarrhea. If there is no inflammation, it's like 100% that motility is your issue and there is HOPE (true to your name!) it will resolve with time as it did with me.
The low iron is fixable with meds or in some cases infusions. I once saw a guy in my infusion room who had a bag with what looked like a deep red solution hooked up to his IV. I asked him what it was and he told me it was iron. Not sure what was causing his underlying iron deficiency.
Excess motility may be causing the low iron issue with constant BMs. Your sodium could be low too, for the same reasons. Keep a close eye on both. As you get older, these deficiencies can become hugely hazardous to your health. At age 25 not big of a deal but when you get to 61, you really need to stay on top of it.
Good luck- it may resolve.
