A blood glucose level information processing apparatus, method and program provide blood glucose values and blood glucose value information within a period or range desired by a user without imposing cumbersome operation on the user. The apparatus, method and program provide blood glucose values and blood glucose value information within a period or desired range by acquiring blood glucose levels measured by a blood glucose level measuring device and date/time of measurement at which the blood glucose levels are measured, displaying a line graph obtained by plotting the blood glucose values within a predetermined period. A slide bar can also be provided, for example on a graph display screen image, whereupon if the slide bar is moved, only the blood glucose values corresponding to a preceding period backdating in response to the amount of movement of the slide bar are plotted on a line graph along a time series.
