1 - 15 . (canceled) 
     
     
         16 . A system comprising:
 a pump configured to deliver insulin;   a user interface configured to display information to the user;   a memory configured to store a target glucose level;   a processor configured to control the pump and operatively connected to the memory and the user interface, the processor configured to:
 receive one or more glucose levels of the user; 
 determine from the one or more glucose levels that the user may have a glucose level lower than the target glucose level in the near future; and 
 upon determining that the user may have a glucose level lower than the target glucose level in the near future, providing a low glucose alert to the user on the user interface notifying the user that the user may have a glucose level lower than the target glucose level in the near future. 
   
     
     
         17 . The system of  claim 16 , wherein the processor is further configured to provide a recommendation to the user to address the glucose level lower than the target glucose level. 
     
     
         18 . The system of  claim 17 , wherein the recommendation is to eat carbohydrates. 
     
     
         19 . The system of  claim 17 , wherein the recommendation is for the user to check a blood glucose level of the user. 
     
     
         20 . The system  16 , wherein the processor is configured to review a current level of insulin on board of the user in determining whether the user may have a glucose level lower than the target glucose level in the near future. 
     
     
         21 . The system of  claim 20 , wherein the processor is further configured to calculate a future glucose level based on the one or more glucose levels and the level of insulin on board. 
     
     
         22 . The system of  claim 16 , wherein the processor is further configured to calculate a carbohydrate value required to raise a glucose level of the user to the target glucose level. 
     
     
         23 . The system of  claim 22 , wherein the processor is further configured to display the carbohydrate value as a suggestion to the user to consume the carbohydrate value. 
     
     
         24 . The system of  claim 16 , wherein the user interface is disposed on the pump. 
     
     
         25 . The system of  claim 16 , wherein the processor is further configured to access a food database and to display on the user interface one or more foods the user is recommended to eat. 
     
     
         26 . A system comprising:
 a pump configured to deliver insulin;   a user interface configured to display information to the user;   a memory configured to store a target glucose level range within which the user's glucose level is intended to be maintained;   a processor configured to control the pump and operatively connected to the memory and the user interface, the processor configured to:
 receive one or more glucose levels of the user; 
 determine from the one or more glucose levels that the user may have a glucose level below the target glucose level range in the near future; and 
 upon determining that the user may have a glucose level lower than the target glucose level in the near future, providing a low glucose alert to the user on the user interface notifying the user that the user may have a glucose level lower than the target glucose level in the near future, wherein the low glucose alert provides a recommendation to the user to eat carbohydrates and to test a current blood glucose level of the user. 
   
     
     
         27 . The system  26 , wherein the processor is configured to review a current level of insulin on board of the user in determining whether the user may have a glucose level below the target glucose range in the near future. 
     
     
         28 . The system of  claim 27 , wherein the processor is further configured to calculate a future glucose level based on the one or more glucose levels and the level of insulin on board. 
     
     
         29 . The system of  claim 26 , wherein the processor is further configured to calculate a carbohydrate value required to raise a glucose level of the user into the target glucose range. 
     
     
         30 . The system of  claim 29 , wherein the processor is further configured to display the carbohydrate value as a suggestion to the user to consume the carbohydrate value. 
     
     
         31 . The system of  claim 30 , wherein the processor is further configured to allow editing of the displayed carbohydrate value. 
     
     
         32 . The system of  claim 29 , wherein the processor uses one or more correction factors to calculate the carbohydrate value. 
     
     
         33 . The system of  claim 26 , wherein the processor is further configured to display a current glucose level. 
     
     
         34 . The system of  claim 26 , wherein the user interface is disposed on the pump. 
     
     
         35 . The system of  claim 26 , wherein the processor is further configured to access a food database and to display on the user interface one or more foods the user is recommended to eat.
