A medical infusion pump system, comprising: a portable pump housing that receives insulin for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the insulin through a flow path to the user; a controller that activates the pump drive system to dispense the insulin from the portable pump housing; a monitoring device that communicates glucose information to the controller, the glucose information being indicative of a blood glucose level of the user; and a user interface coupled to the controller including a display device that contemporaneously displays a glucose value indicative of the blood glucose level of the user and a total insulin load indicative of bolus and basal insulin dosages that have been dispensed but not yet acted in the user, wherein the total insulin load is determined by the controller according to a function that accounts for a sum of (i) the bolus insulin dosages that have been dispensed into the user but not yet acted in the user, (ii) the basal insulin dosages that have been dispensed into the user from the portable infusion pump system but not yet acted in the user; and (iii) a previous food component based upon previous food intake that has not yet metabolized in the user, wherein the previous food component is treated as a negative insulin unit value; and wherein the controller is to perform operations including: receiving user input indicative of a request to suggest a bolus dosage, receiving user input indicative of a proposed food intake to be consumed by the user of the portable infusion pump system, receiving glucose information indicative of the glucose level of the user, determining a bolus suggestion value according to a function that includes the total insulin load of the user, and displaying the bolus suggestion value on the display device of the portable infusion pump system. a portable pump housing that receives insulin for dispensation to a user, the pump housing at least partially containing a pump drive system to dispense the insulin through a flow path to the user; a controller that activates the pump drive system to dispense the insulin from the portable pump housing; a monitoring device that communicates glucose information to the controller, the glucose information being indicative of a blood glucose level of the user; and a user interface coupled to the controller including a display device that contemporaneously displays a glucose value indicative of the blood glucose level of the user and a total insulin load indicative of bolus and basal insulin dosages that have been dispensed but not yet acted in the user, wherein the total insulin load is determined by the controller according to a function that accounts for a sum of (i) the bolus insulin dosages that have been dispensed into the user but not yet acted in the user, (ii) the basal insulin dosages that have been dispensed into the user from the portable infusion pump system but not yet acted in the user; and (iii) a previous food component based upon previous food intake that has not yet metabolized in the user, wherein the previous food component is treated as a negative insulin unit value; and wherein the controller is to perform operations including: receiving user input indicative of a request to suggest a bolus dosage, receiving user input indicative of a proposed food intake to be consumed by the user of the portable infusion pump system, receiving glucose information indicative of the glucose level of the user, determining a bolus suggestion value according to a function that includes the total insulin load of the user, and displaying the bolus suggestion value on the display device of the portable infusion pump system. receiving user input indicative of a request to suggest a bolus dosage, receiving user input indicative of a proposed food intake to be consumed by the user of the portable infusion pump system, receiving glucose information indicative of the glucose level of the user, determining a bolus suggestion value according to a function that includes the total insulin load of the user, and displaying the bolus suggestion value on the display device of the portable infusion pump system.
