Crohn's disease can cause diarrhea, sometimes occurring two to three times a day, and in severe cases, it can happen dozens of times per day. The diarrhea caused by Crohn's disease may include mucus-like or pus-blood-like stool, and it is also accompanied by chills, fever, weight loss, etc. In severe cases of Crohn's disease, there is a possibility of intestinal perforation. Therefore, once Crohn's disease is diagnosed, aggressive treatment is necessary. Initially, drugs such as mesalazine can be considered for treatment. If the treatment is not effective, it may be necessary to consider using steroids or immunosuppressants. If necessary, biological treatments such as infliximab may be used.
