Hi Aman, Thanks for your query. Hard stools stretch, rupture and bruise the delicate inner lining of the anal canal, which causes anal fissures. The mainstay of treatment is to avoid constipation. Take high fiber diet including lot of green leafy vegetables, plenty of water daily; and, 2 teaspoonful of Isabgol husk twice daily (regularly). Once the stools become normal, anti-fissure rectal ointment and a short course of antibiotics (to eradicate fissures infection) should be used. Long-term use of Isabgol is safe, instead of Cremaffin. Get a Thyroid Profile done to rule out/detect under-active thyroids, since hypothyroidism is a common cause of chronic constipation. Consult your doctor and apprise him of my opinion. I am certain that he will agree with me and will prescribe the advised drugs in appropriate doses.
