Hemorrhoids do not usually cause diarrhea. Hemorrhoids are diseases that occur around the anus, usually above or below the dentate line, and may form swellings on the surface of the anus, or may cause bleeding from the anus after a bowel movement. If diarrhea is prolonged, hemorrhoids may form, mainly because the process of defecation causes varicose veins in the rectum to move downward or the anal cushion to move downward. The treatment of hemorrhoids requires a light diet, which means eating fresh vegetables and fruits as much as possible and avoiding spicy and irritating foods. If the patient has constipation or if the patient has diarrhea, it is important to come to treatment in a timely manner, and you need to exercise properly and avoid sitting or standing for too long. If hemorrhoids form, you need to take oral medication for symptomatic treatment, such as Diosmin or Mai Zhi Ling, and you can also apply Ma Ying Long hemorrhoid cream on the surface of the hemorrhoids for symptomatic treatment. If the patient has diarrhea, it may be caused by enteritis, possibly caused by polyps inside the rectum or rectum, or sigmoid colon, and can be treated with fluids if necessary, or a colonoscopy can be done to clarify the diagnosis.
