Hi I can understand your concern... You probably here having hepatitis infection. So vomitting is common symptom as constitutional symptom.... Viral marker done... Here is advise regarding diet..... Take low fat diet to rest liver. Soft and bland diet taken... Frequent sips of fruit juice taken... Apple, pear , mango , papaiya like fruit can be taken... In lunch include green leafy salad. In dinner apple , carrot juice and vegetable soup helpful.... Sugar Cain juice good to take.... Boiled vegetables taken more rather then fried.... Take crushed one tsp carom and cumin seed with water daily early in morning... Non veg and junk food totally avoided for few days... Take care .... You can be helped further if need still more advise. Dr.Parth
