A data management unit for supporting health control, the unit comprising: a processor with a dose helper adapted to provide a dose helper functionality with regard to a predefined medicament, wherein the dose helper functionality is a titration method which determines a medicament dose value or its corrective amount, preferably a basal long-acting insulin dose value, to be administered by a patient, based on a measured physiological parameter, preferably based on measured blood glucose values and/or information about hypoglycemic and/or hyperglycemic events, a display connected to the processor and adapted to visibly and/or audibly and/or tangibly display received messages, a data input adapted to input data and/or requests and connected to the processor, a data storage adapted to store a usual dose time and/or a dose time window, a predefined recommendation message, a time of a dose helper request, a predefined criterion, wherein the dose helper request relates to requesting the execution of the dose helper functionality, wherein the data storage is connected to the processor, a clock unit adapted to determine the absolute time of a dose helper request received by the data input, wherein the clock unit is connected to the processor, wherein the processor is adapted to initiate storing at least the time of a dose helper request that is outside the dose time window around the usual dose time in the data storage, wherein the processor is further adapted to execute the dose helper functionality only if the time of the most recent dose helper request is within the dose time window around the usual dose time, characterized in that the processor is further adapted to initiate sending a recommendation message for change of the usual dose time and/or dose time window to the display if the time distribution of most recent dose helper requests within a predefined time period corresponds to the predefined criterion, wherein the processor is further adapted to check as the predefined criterion whether the number of most recent dose helper requests outside the dose time window is higher than a predefined maximum number during the predefined time period, wherein the predefined number and predefined time period is stored in the data storage, wherein the processor is further adapted to calculate a modified value of the usual dose time and/or dose time window based on the time of at least a part of the dose helper requests within the predefined time period, wherein the recommendation message recommends to change the usual dose time and/or the dose time window according to the respective calculated modified value. a processor with a dose helper adapted to provide a dose helper functionality with regard to a predefined medicament, wherein the
