There are many ways to treat Ulcerative Colitis such as -
Modern Medicine- has drugs which can treat and maintain remission. Steroids are mostly used to treat a flare up and get it under control; if they fail there are other more powerful drugs like cyclosporine which can settle things down. Then drugs like mealazine or colazide are used to keep the inflammation in check. Often anti inflammatory enemas are used as well.
Homeopathy - can be very effective in cases of Colitis, a homeopath will provide specific remedies for each individual patient, I have tried this myself and it worked very well indeed.
Probiotic Treatment - Has been shown in several medical trials to be as effective as anti inflammatory drugs in maintaining remission in Ulcerative Colitis, and they have also even used to treat colitis flare ups successfully.
Herbs - such as Boswellia, Turmeric and Ashwaganda are very effective anti inflammatory and can be used successfully to maintain remission in patients. Boswellia alone was used in one study and proved to be effective as pharmaceuticals in maintaining remission.
Surgery - can be used to remove the colon, which is sometimes necessary in extreme cases, although not so much these days.
Diet - can be very helpful in reducing symptoms, following a good anti inflammatory diet can often be one of the best things a colitis sufferer can do.
Helminthic Worm Therapy - This is where helminthic worms are ingested and has shown promise in the treatment of Ulcerative Colitis, although it doesn't sound very appealing - but if it works!
Bio Energy Healing - This may sound a bit unusual but science is proving it to be real these days and if you can find a really good energy healer they can do some amazing things.
