A. Hai good evening !! Due to body heat,low intake fibre foods ,water ,fluid intake cause constipation. Include water,fluids, fruits,vegetables(papaya, pear,apple,banana,orange,grapes,carrot, cucumber,bottle gourd) curd,ragi ,jowar . Do tummy massage with castor or coconut oil this helps in instant relief from gas,constipation issues.
