These two diseases are similar but have different characteristics. IBD is considered an autoimmune disease that is, the body's immune system attacks itself. These causes may be interconnected. IBS can result in abdominal pain, cramping, diarrhea, fever, rectal bleeding, constipation, and weight loss. Once this inflammation is established, it remains forever.
Ulcerative colitis can be quite mild or very severe.
The most common symptoms are diarrhea and bleeding. A correct diet is important in combating ulcerative colitis. Because it may be partially due to food sensitivities, you should keep a daily record of foods and how they may affect you. In general, you should eat plenty of vegetables. If you cannot tolerate them raw, steam them.
