Sir, My eldest son is 8 years old now. Upto 4 - 5 years age he could not have fatty items, milk, egg, meat etc. Frequently he suffered from diarrhea and stomach pain. We consulted so many doctors at that time. Now though he has got relieved from pain with age but his health is not sound(under weight and unexpectedly thin). Therefore, I want to consult with the specialist related with this type of problems in reputed Hospital like yours. Please send details about the doctors and their contact addresses and if possible how to proceed for treatment. Thank you, with regards, XXXX
