Hi MichUC, happened to see your post & wanted to respond. I am sorry I cannot answer your question, however, I have heard of people having issues with absorption after bowel surgeries. Some drs say yes & some say no. My thoughts are to ask your surgeon this question. Perhaps call & speak to the nurse & she can ask the dr & let you know something.
Also we have an active UC forum here & I know some of them have had surgery too. You may want to pop over there too.
