What should I do if I experience rectal bleeding due to an anal fissure?

Severe constipation or hemorrhoids may cause anal bleeding. Minor bleeding is generally not a serious concern; however, frequent or heavy bleeding requires prompt and effective treatment to stop the bleeding. So, how is bleeding caused by an anal fissure treated?

How to Treat Bleeding Caused by an Anal Fissure

Initial management of bleeding from an anal fissure typically involves conventional hemostatic medications. Patients are advised to take vitamin K1, Zhizhimin (a traditional Chinese medicine), or Anluoxue (carbazochrome sodium sulfonate). If necessary, intravenous administration of tranexamic acid and hemocoagulase may be required. Concurrently, treatment of the underlying condition is essential. For example, patients with hemorrhoids may take Huazhiling tablets; those with constipation may use phenolphthalein tablets or other laxatives that lubricate the intestines and promote bowel movements. In cases where hemorrhoids are the cause, topical treatments such as Moschus Hemorrhoid Ointment or Compound Carrageenan Suppositories may be applied rectally. For constipated patients, glycerin suppositories (e.g., Kaisailu) or mild soap enemas may help relieve constipation.

Inadequate intestinal moisture prevents stools from remaining soft and lubricated. Dry stools and dehydrated intestinal mucosa can lead to constipation. Therefore, to prevent constipation, it is crucial to maintain adequate daily fluid intake. A light, bland diet is recommended in daily life; excessively spicy foods may irritate the gastrointestinal tract and contribute to constipation.

A small number of patients neglect proper perianal hygiene. Excessive dryness or accumulation of foreign material around the perianal area may reduce local tissue elasticity, increasing the risk of anal fissures during defecation. Therefore, regular perianal cleansing—ideally via bathing—is recommended to keep the perianal region moist and enhance lubrication. We hope this information proves helpful.
