According to the present invention, a toilet system having a user health checking function comprises a mode selection unit, a weight measurement unit, a flatus analysis unit, an active oxygen sensing unit, and an operation control unit to operate the weight measurement unit to determine a weight of a user if a determined operation mode is a weight measurement mode, use a signal applied from the flatus analysis unit to determine components and a content of flatus and whether a content of each component exceeded a reference content to determine whether the content of each component is normal if the determined operation mode is a flatus analysis mode, use a signal applied from the active oxygen sensing unit to determine an active oxygen amount of urine and determine whether the determined active oxygen amount is normal if the determined operation mode is a urine analysis mode, execute all operations executed in the weight measurement mode, the flatus analysis mode, and the urine analysis mode if the determined operation mode an entire analysis mode to determine the weight of the user, determine components and a content of flatus, compare a content of each determined component and the corresponding reference content to determine whether the content of each determined component exceeded the reference content to determine whether the content of each component is normal, determine an active oxygen amount of urine, and compare the determined active oxygen amount and a reference active oxygen amount to determine whether the determines active oxygen amount exceeded the reference active oxygen amount to determine whether the determined active oxygen amount is normal.본 발명의 사용자 건강 체크 기능을 갖는 변기 시스템은 모드 선택부, 체중 측정부, 방귀 분석부, 활성산소 감지부, 그리고 판정된 동작 모드가 체중 측정 모드이면 체중 측정부를 동작시켜 사용자의 몸무게를 판정하고, 판정된 동작 모드가 방귀 분석 모드이면 방귀 분석부로부터 인가되는 신호를 이용하여 방귀의 성분 및 함량, 각 성분의 함량이 기준 함량을 초과했는지 판정하여 각 성분의 함량의 정상 여부를 판정하며, 판정된 동작 모드가 소변 분석 모드이면 활성산소 감지부로부터 인가되는 신호를 이용하여 소변의 활성 산소량을 판정하고, 판정된 활성 산소량의 정상 여부를 판
