Constipation/Fissure. Not used pappaya.

My wife, she has trouble with constipation/fissure since long time. Started with constipation some 14 years ago, later developed into few fissure scars in the anus, and now it has eventually evolved into bigger fissure warts making passing the stool troublesome. Have to drink a lot of water to get the motion passing started. Have been trying sitz bath in salt+warm water. Is there any way I can get rid of this constipation/fissure trouble..(have been a vegetarian and trying controlling diet very well like not taking spicer foods, consuming fibre rich food etc. Pappaya used to help well, making the motion loose .. now after marriage ( got married recently) I have not used pappaya ... thanks in advance for any pointers in this regard
