It’s a common condition and usually not serious, but it can be very painful. 🔍 Causes Passing hard or large stools Chronic constipation or diarrhea Straining during bowel movements Childbirth Anal trauma (e.g., during anal sex) In rare cases: Crohn’s disease, HIV, tuberculosis, or cancer ✅ Symptoms Sharp, burning, or stabbing pain during or after bowel movements Bright red blood on toilet paper or in stool Visible tear near the anus Itching or irritation Spasm of the anal sphincter (can worsen the tear) 📌 Types of Anal Fissures Type Description Acute Recent tear, looks fresh, usually heals in a few weeks Chronic Lasts >6 weeks, edges may become thickened or scarred, may require surgery 💊 Treatment 🔹 Conservative/Home Treatments (First-Line) High-fiber diet (25–35g/day) to soften stool Stool softeners (e.g., docusate) Warm sitz baths (10–20 minutes, 2–3 times daily) Drink plenty of water Avoid straining or sitting too long on the toilet 🔹 Medications Topical anesthetics (e.g., lidocaine) for pain Topical nitroglycerin or calcium channel blockers (e.g., nifedipine, diltiazem) to relax the sphincter and increase blood flow for healing Botox injection into the anal sphincter (relaxes muscle to help healing; lasts a few months) 🔧 Surgical Options (for chronic or non-healing fissures) Procedure Description Lateral internal sphincterotomy (LIS) Gold standard; small cut in sphincter to reduce spasm and promote healing Fissurectomy Removal of scarred tissue Advancement flap Used for fissures not healing due to poor blood supply Surgery has high success rate (>90%) but slight risk of incontinence (gas or stool) 🧼 Prevention Tips Maintain regular bowel habits Use fiber supplements if needed (e.g., psyllium) Avoid straining Keep the anal area clean and dry Treat any underlying constipation or diarrhea 🚨 When to See a Doctor Pain lasts more than 6 weeks Recurrent bleeding No improvement with home treatment Suspected chronic fissure or other anal conditions (e.g., hemorrhoids, abscess, cancer)
