In general, whether a constipated patient sees anorectal or gastroenterology needs to be determined on a case-by-case basis. If the patient suffers from hemorrhoids, perianal abscess or anal fissure, etc., the patient may consciously prolong the time of defecation due to the fear of anal pain and bleeding during defecation, thus leading to constipation. If the constipation is caused by the above factors, it is necessary to go to the anorectal department of the hospital for consultation. If the patient does not have the above conditions, simply appear constipation or accompanied by other symptoms of digestive discomfort, it is recommended to go to the gastroenterology department on the line, to clarify the specific cause of the disease. Whether a constipated patient should see anorectal or gastroenterology depends on the specific situation, if you can not judge for yourself, you can consult with the outpatient service center of your local hospital.
