I'm still looking for ways to avoid surgery and still get rid of this colitis. Here's an interesting article from Omega3.US. It reads, in part:

Fish oil, nature's most potent anti-inflammatory, helps relieve the severity of ulcerative colitis (UC). And, according to a study published in the American Journal of Gastroenterology (Vol. 87: 432-37), fish oil treatment allows many patients to reduce or eliminate medications.

An article by Elaine Moore at Suite 101 tells us:

...........deficiencies of omega-3 fatty acids cause an erratic immune response. Furthermore, increased levels of omega-6 oils, in turn, leads to increased levels of the pro-inflammatory cytokines interleukin-1 and leukotriene LTB-4. High levels of these cytokines are seen in arthritis, Crohn's disease, ulcerative colitis, systemic lupus erythematosus (SLE), psoriasis, multiple sclerosis, depression and migraine headaches. According to several studies, omega-3 fatty acid deficiencies contribute to neurological disorders.
