If your fissures are caused by constipation or diarrhea, you can change a few habits to help lessen the strain on the anal canal. These steps can help relieve symptoms and encourage healing in most cases. Stay hydrated. Drink plenty of caffeine-free fluids throughout the day. (Too much alcohol and caffeine can lead to dehydration.) Eat a fiber-rich diet. To avoid constipation, your goal should be to get 20 to 35 grams of fiber every day. You can gradually increase the amount of fiber you eat by having more: Wheat bran Oat bran Whole grains, including brown rice, oatmeal, and whole-grain pastas, cereals, and breads Peas and beans Citrus fruits Prunes and prune juice Try fiber supplementsif you can’t get enough fiber from food. They can help soften stools and make you more regular. To avoid gas and cramping, gradually raise the amount of any fiber supplement you take until you reach the recommended dose. Over-the-counter laxatives may help if adding more fiber to your diet does not. Before taking any laxatives, ask your doctor what she suggests. Don t ignore your urge to go. Putting off bowel movements for later can lead to constipation; stools may become harder to pass and end up causing pain and tearing. Don t strain or sit on the toilet too long. This can increase pressure in the anal canal. Gently clean and dry your anal area after each bowel movement. Avoid irritants to the skin, such as scented soaps or bubble baths. Get treatment for chronic constipation or ongoing diarrhea. Sitz baths, or hip baths, can promote healing of an anal fissure. By soaking the rectal area in a tub of warm water -- two or three times a day for 10 to 15 minutes -- you can clean the anus, improve blood flow, and relax the anal sphincter. These habits are usually enough to heal most anal fissures within a few weeks to a few months. But when they aren t enough, ask your doctor about other treatments. Medications for Treating Anal Fissures Nitrate ointment: Your doctor may prescribe one of these to help raise blood flow to the anal canal and sphincter, which helps fissures get better faster. Some side effects may include headaches, dizziness, and low blood pressure. Nitrate ointment should not be used within 24 hours of taking erectile dysfunction medicines like sildenafil (Viagra), tadalafil (Cialis), or vardenafil (Levitra). Calcium channel blockers: These are blood pressure-lowering medications. Some of the topical ones can treat anal fissures, too. Side effects may include headaches. You can also take calcium channel blockers by mouth to treat anal fissures, although healing may be slower and the side effects more pronounced. Botox injections: When topical treatments don t work, injecting botulinum toxin type A (Botox) into the sphincter is sometimes the next step. Botox injections temporarily paralyze the sphincter muscle, relieving pain and encouraging healing in 60% to 80% of patients. You may not be able to control your bowel movements or passing gas, but it s temporary. Researchers are still reviewing Botox to figure out the best dosage, injection sites, and amount that is safe and healthy to treat anal fissures. Surgery You probably won t need surgery for anal fissures unless other forms of treatment haven t worked. The surgery, called a lateral internal sphincterotomy (LIS), involves making a small cut in the anal sphincter muscle. It reduces pain and pressure, allowing the fissure to heal. The pain from this surgery is usually mild. It hurts less than the fissure itself. The surgery might be followed by a temporary inability to control gas, mild fecal leakage, or infection. But in most cases, complete healing of fissures takes place within 8 weeks after surgery. so the choice of treatment only your doctor to whom your are already going can tell according to your history
