Shankhavati 0 - 1 - 1/2 Since th4 past 4 months the symptoms only have ameliorated mildly but not returned to normal. I still have loss of appetite, mild sour saliva after meals, on-off epigastric pains, pains in hypogastric regions , mild constipation. I eat sufficient fibre in the diet with sufficient vegetables. Even fermented curd rice gives me heaviness. I cannot take lentils as they become difficult to digest, ghee and oils diffllicult to digest I am taking the simplest of foods 1. Morning Fermented curd rice, 1 small chapati, beetroot and carrot boiled sabji 2. Afternoon. Chapati , plain white rice, Green cauliflower peas sabji, Yellow pumpkin and raw banana sabji.
