A. Hello good morning !! Include fibre rich foods - Papaya,pear,grapes,apple,banana, bottle gourd,carrot,cucumber ,curd,ragi,jowar in regular meals to increase bowel movements. Give enough water and fluids. Avoid cow milk for two days and check the stools,because for a few body types cow milk causes constipation,body heat.
