What should I do if I have an anal fissure with bleeding?
Many individuals experience rectal bleeding during bowel movements, sometimes accompanied by anal pain—a highly distressing symptom. While many assume rectal bleeding is caused by hemorrhoids, in fact, numerous other conditions besides hemorrhoids can lead to this symptom. So, what should one do if an anal fissure causes bleeding?
What to Do for Bleeding Caused by an Anal Fissure
For rectal bleeding, hemostatic medications—such as vitamin K1 and hemostatic agents—should be administered promptly under a physician’s guidance. Concurrently, Huazhi Ling tablets and phenolphthalein tablets may be used to address the underlying condition, while Moschus Hemorrhoid Ointment and Kaisailu (a topical agent) can be applied locally. In severe cases, timely surgical suturing—or physical therapies and sclerotherapy injections—may be required. If bleeding occurs alongside an anal fissure, it is likely due to an anal fissure. The primary cause of bleeding from an anal fissure is trauma—tearing or laceration of the local anal mucosa and sphincter muscle—often triggered by straining during defecation, especially when stools are hard and dry. To alleviate bleeding from an anal fissure, oral Yunnan Baiyao capsules may be taken for hemostasis. Locally, Kangfuxin liquid and Kushen wash solution may be applied via warm compresses to promote hemostasis and healing of the fissure.

Additionally, treatment aimed at softening stools is essential. Prior to defecation, applying sesame oil around the anus helps prevent friction between stool and the local mucosa. Oral administration of Maren Runchang Wan (a traditional herbal formula) may also be used to lubricate the intestines and facilitate smooth bowel movements. For early-stage (acute) anal fissures, conservative medical management—including topical stool-softening and bowel-regulating agents—is often sufficient. However, for recurrent or chronic (old) anal fissures—where the fissure has progressed to an ulcer with deep tissue involvement and impaired drainage of secretions—surgical intervention becomes necessary.

Patients are advised to maintain a healthy diet: consume light, easily digestible foods; drink ample water; and increase intake of high-fiber foods to prevent constipation and hard stools. We hope this information proves helpful.
