A method for determining a users body information in a mobile terminal includes determining whether a user touch is detected on a touch panel, which incorporates a Bio Micro Electric Mechanical System (MEMS) technology, and if so, determining the users body information which in turn is transmitted to an upper node. Body information analysis results are received from the upper node and displayed subsequently. As a result, a mobile user has an advantage of managing his or her health via on line using a touch panel of a mobile terminal without visiting a hospital separately.
