The common symptom of inflammatory bowel disease is the most common symptom, namely Crohn’s disease or ulcerative colitis. It has different symptoms, but most of them have abdominal pain, blood in the stool, diarrhea, and systemic symptoms. For example, after the onset of the disease, many patients suffer from wasting, loss of appetite, and systemic symptoms such as joint pain that often accompany the disease. If the inflammatory bowel disease is Crohn’s disease, its symptoms are mainly diarrhea and abdominal pain, which are different from ulcerative colitis. In turn, the symptoms of ulcerative colitis are mainly mucus and blood stools. Mucus and blood stools, i.e., many people have diarrhea with something like mucus, often accompanied by blood in the stool, sometimes up to a dozen times, and sometimes 2-3 times. This symptom is recurrent and causes great pain to the patient. In addition to bloody stools and abdominal pain, some symptoms include general discomfort, bloating, nausea, and vomiting in the patient. Patients with Crohn’s disease also have fistulas, anal or skin fistulas, which form long-term, chronic secretions because of sinus tract formation caused by the disease in the intestine. So the lesions can be very painful for the patient, and the treatment is actually a tricky one.
