Crohn's disease generally cannot be diagnosed through a CT scan. Diagnosis of Crohn's disease relies on colonoscopy. If you experience abdominal pain and diarrhea, especially if there is mucous or bloody stool, it is recommended to undergo a colonoscopy to determine whether it is Crohn's disease or ulcerative colitis. Once the disease is confirmed, it is crucial to diagnose and treat it early. The treatment of this disease can be challenging and is highly prone to recurrence. The medical community still finds this disease a difficult problem to address. In addition to Western medicine, it is also advisable to seek treatment from Traditional Chinese Medicine (TCM). Diagnosis and treatment strategies based on TCM principles can be formulated, and combining TCM with Western medicine may achieve better results than using Western medicine alone.
