I am Chat Doctor answering your query. With your history of diarrhea and enlarged liver with deranged liver function test, together it points to Typhoid (Enteric) fever. If I were your doctor, I would also advise you for a Ty phi dot test and a tidal test for a confirmed diagnosis. However, hepatitis and gastroenteritis both could exist separately in the same individual. This needs a general physical examination along with reports of related investigations. Therefore, I would advise you to go to the ER of your nearest hospital and get yourself clinically assessed and investigated. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor. </s>
