HI Well come to HCM I really appreciate your concern, I had gone through the history given here, and let me inform you some few thing first indigestion is not the pure form of disease but it is the condition (More or less ) it is highly connected with the mental condition of the patient, diet habit, food habit, even the IBS is also kind of functional disease and not the pathology, changing the life style, diet habit, positive attitude, exercise, stress free life would be much helpful. People are always using the word Stomach Problem but what kind of problem is there not being explained stomach problem does not create any sense. If she has not been brought to investigations then better to get all that done just on routine basis, like Ultrasonography, routine blood test, urine test, and others hope this information helps.
