Hello, utkarsh.bhalla, From the description of findings at sigmoidoscopy , you have Colitis . I hope the doctor did biopsies to determine the type of colitis. Crohn s disease can also produce similar changes. Ask your doctor if they ruled this out. You are a young man and I am sure very active. It is very important that your colitis gets under control and stays in remission. There is no cure for Crohn s. Ulcerative colitis can be cured by removal of the entire colon if the entire colon is affected. There are very effective drugs available now. Probiotics like VSL-3 may help but is not a treatment for colitis. Initially , if the flare up is severe , we use short term cortisone like Budesonide to get it under control. Then taper off cortisone and put patients on Mesalamine, 6-MP type of drugs to maintain healing. There are Biologicals such as Infliximab and other new ones that are very effective. You have to be under close supervision with blood tests etc. Milk and dairy products can aggravate the colitis. High protein diet and reducing fatty ,greasy,fried foods are helpful. It is O.K. to take Vitamin supplements. You can discuss these with your doctor who performed sigmoidoscopy and take proper action. I wish you the very best.
