Colitis is a type of inflammatory bowel disease (IBD) similar to Crohn's disease. Both cause long-term inflammation, but only colitis causes ulcers. Most people with colitis experience flare-ups combined with periods of remission. Early diagnosis is crucial and it is important that both affected people and their physicians closely observe symptoms.
Diarrhea mixed with blood and mucus is the most common symptom of colitis. During a flare-up, individuals experience a gradual onset of loose, watery stool that can last for weeks. Though this type of IBD is challenging to trace back to food or environmental triggers, during a flare-up it is best to avoid foods that aggravate diarrhea.
