The most common signs of IBD are diarrhea, abdominal pain, and unexplained weight loss. UC may also cause blood, mucus, or pus in the stool, and urgent or persistent feelings of needing to have a bowel movement (tenesmus). Crohn’s disease may cause additional symptoms, including joint or eye pain, nausea, or anemia. Severe cases of UC or Crohn’s may also lead to fever or lasting fatigue.
The symptoms of IBD naturally go through phases of greater severity during flares, and spontaneous resolution during periods of remission.[1] [2] [3]
