The present invention refers to a data management unit that supports health care, and a corresponding medical device, which includes a plurality of measurements of physiological parameters, such as fasting blood glucose levels, and an associated time stamp for each measurement. A data storage device (130) adapted to store a variety of trend categories, such as increasing trend, stable trend and decreasing trend, preferably each visible symbol (201, 202) on the display (162) ) And / or a trend indicator (164) adapted to be shown as a respective audible signal from the loudspeaker, and a first group of measurements and a second group of measurements as data storage (130) ) From the plurality of measurements, each associated time stamp of the first group of measurements is within a predetermined first time interval, And a processor (140) adapted to select each associated time stamp of the group of measurements to be within a predetermined second time interval, the second time interval being a first time. More recently than the interval, the processor is further adapted to calculate a first average value as an intermediate value of the first group of measurements, and a second average value of the second group of measurements. Depending on the result of the comparison between the second average value and the first average value, the processor (140) indicates that the trend indicator (164) is one of various trend categories, eg, an increasing trend, Interact with the trend indicator (164) to indicate a stable or decreasing trend. In addition, the present invention refers to corresponding methods and computer programs for indicating trends, and corresponding computer program products.本発明は、健康管理を支援するデータ管理ユニット、および対応する医療デバイスに言及し、これらは、・生理学的パラメータ、たとえば空腹時血糖レベルの複数の測定値と、測定値ごとの関連のタイムスタンプとを記憶するように適用されたデータ記憶装置（１３０）と、・様々な傾向カテゴリ、たとえば増加傾向、安定傾向および減少傾向を、好ましくはディスプレイ（１６２）上のそれぞれの可視記号（２０１、２０２）として、および／またはスピーカからのそれぞれの可聴信号として示すように適用されている傾向インジケータ（１６４）と、・第１の群の測定値および第２の群の測定値をデータ記憶装置（１３０）の複数の測定値から、第
