Hi Dear, Understanding your concern. As per your query your daughter have symptoms of severe indigestion and nausea which is because you are suffering from viral infection which is leading to electrolyte imbalance in body. It is due to food intolerance and infection by H. Pylori bacteria. Need not to worry. I would suggest you to visit gastroenterologist once and get complete examination done. You should go for blood test and barium study examination. Avoid taking large meals at a time and take small and frequent meals. If fever increases do tepid sponging as well with cold water. She should take multivitamin tablets. Start taking Ofloxacin along with antacids to immediate avoid symptoms. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
