vomiting and stomach

I am 43 year old person and my wife is 30 years old. we married before last 8 month. I know my wife before marriage from last 3 year she is lean and thin.she has some skin problem as bubble in summer and rainy season only.except she has no any problem. But just after two month of marriage she is suffering always from tendency of gas,vomiting,stomach (abdomen etc.) after interval of one week to 15 days. Blood report is normal except nutrophils.xray is clear.altrasound showing some acitis problem in lower side of abomain. But doctor said that there is no reason of acitis it is just any infection and giveing her cerom 500 Recifax, velgut. cyradee etc. when the vomiting symptomps arise we give him cyardee(for gas) and ozetron for vomiting and it control in some hour or day. but pain become continue for next 2 days. after two days she become normal. again after 15 days or 20 days it become repeate. Due to taking medicine the problem is in control but the main cause of worry that why it repeat again and again. Dr saying it is just infection and it will repeat again and again if any type of eating heavey food or abnomal food or elergic food. How it can control. I want heamopathic treatment please suggest.
