Chronic colitis and ulcerative colitis are both inflammatory diseases of the intestines. Chronic colitis includes ulcerative colitis, Crohn’s disease, and ischemic enteritis. Chronic colitis and ulcerative colitis may be triggered by the presence of infected lesions in the intestines themselves, or by inflammation in other organs that lead to infection in the intestines. Viral infections are one of the most common causes of chronic colitis and ulcerative enteritis. Patients with chronic colitis will show symptoms such as diarrhea, abdominal pain, mucus, pus and blood stools, while patients with ulcerative enteritis may show symptoms such as mucus, pus and blood stools, diarrhea, abdominal pain, and urgency (discomfort in the lower abdomen, a strong desire to relieve stools, and a feeling of incomplete bowel movement after a bowel movement), and so on. Chronic colitis can choose symptomatic treatment, such as the application of antidiarrheal drugs: montelukast, gastrointestinal antispasmodic drugs: atropine, pro-gastrointestinal dynamics drugs: mosapride. Ulcerative enteritis choose aminosalicylic acid drugs, such as luzosulfapyridine and mesalazine, glucocorticoid drugs such as prednisone. When the patient has abdominal pain and bloating and other symptoms, it is recommended that the patient go to the hospital in time for examination and diagnosis, and under the guidance of the doctor for treatment.
