Most anal fissures can be treated at home by avoiding constipation, taking laxatives or stool softeners, using sitz baths, and using over-the-counter hemorrhoid creams, states WebMD. Patients may use baby wipes instead of toilet paper to prevent discomfort while cleansing after bowel movements.
To prevent constipation while an anal fissure heals, patients should consume high-fiber foods and supplements, drink enough fluids, exercise regularly, and schedule stress-free time for a bowel movement daily, according to WebMD. Consult a doctor while using hemorrhoid creams, laxatives or stool softeners to determine the right dosage, frequency and duration. Patients should not avoid bowel movements, which can exacerbate constipation and make the fissures worse.
