Drjimmy, is your wife T1 or T2? Does she limit her carbs per meal to about 45, and test 1 and 2 hours after the meal to see her numbers? Some fruits are high in carbs, as is most white stuff. IF ITS WHITE, DON'T BITE.
A pump can give you great control, but you still need to pay attention to what you are eating. It sounds like she doesn't have an insulin to carb ratio set up. That makes a BIG difference in control, and how much to shoot. A really good book for insulin users is Think Like a Pancreas. I am not in any way connected to the book or author.
I wear the OmniPod insulin system. It has no tubes. I've been on it for almost 4 years, my A1C is always less than 6.5
T2, OmniPod,Fibro,MVP,CAD,4 level cervical fusion, L5_S1 needs fusion, arthritis all over, need 2 knee replacements, Vit D3, and a lot of other meds!
