Hi. I ve gone through your query and I can understand your anxiety. As you are already taking steroids for ulcerative colitis, I advice you to - rest yourself - Diet : high protein, low residue - meat, chicken, egg, bread, cooked veges etc - No spices strictly - adequate fluids - Also Consuming whey protein supplements seems to be beneficial effects. Hope I have answered your query. Let me know if I can assist you further. Take care. Regards, Dr. Yogapriya V, General and family physician.
