I had surgery for CD 50 years ago when I was 20. They took 4 feet of colon & 7 feet of lower intestine. Had no relapses since then, though have had diarrhea on & off during that time. I have recently started taking Psyllium and that has certainly helped the diarrhea. Now only going to the bathroom twice a day.
I watch my diet a little bit - I don't eat the probable triggers like anything with skins on (tomatoes, cherries, plums, orange/grapefruit pulp juice, nuts etc) but I eat most other things. No problem with coca-cola, wine & beer in reasonable doses (2 glasses).
