Colitis refers to the pathological changes of colon. In order to diagnose colitis, please do colonoscopy as early as possible.
It's right for you to take the whole intestines to treat colitis, but it should be better after colonoscopy is confirmed.
(Dr. Li Hengshuang from Jingxi Hospital of Chaoyang Hospital solemnly reminds: Because you can't see the patient face to face, you can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
